FPL Turkey Point Annual Post-Uprate Monitoring Report FPL-024E for Units 3 & 4 Uprate Project - August 2014 Section 3

3. QUARTERLY GROUNDWATER AND SURFACE WATER SAMPLING The Monitoring Plan (SFWMD 2009a) and the QAPP (FPL 2013b) for this project outline the locations and analytes for the groundwater and surface water sampling and the analyses for quarterly and semi-annual events. Each groundwater location is a cluster of three wells at different depth intervals. The groundwater wells are designated by depth and are defined as S for shallow wells (-15.3 to -34.7 ft North American Vertical Datum of 1988 [NAVD 88] to bottom of screen elevation), M for intermediate wells (-32.8 to -85.7 ft NAVD 88 to bottom of screen elevation), and D for deep wells (-46.4 to -122.2 ft NAVD 88 to bottom of screen elevation). Surface water samples are also designated by depth, i.e., T for top (1 ft below surface) and B for bottom (1 ft above bottom). Samples also were collected from several of the historical wells that have been monitored as part of the ID operations. Since the historical wells (L-3, L-5, G-21, G-28, and G-35) are screened across the entire well depth, samples were collected from two depths (18 ft and 58 ft below top of casing).

From June 2010 to May 2013, samples were collected quarterly at specified locations and were analyzed for the parameters as required in the Monitoring Plan. In June 2013, after review by the Agencies, several sites and parameters were dropped from the sampling. Three sites (TPBBSW-1B, TPBBSW-2B, and TPSWCCS-6 [B and T]) and two bottom stations (TPSWCCS-4B and TPSWCCS-5B) were eliminated. Per the Agencies, the data reductions (Tables 3.0-1 and 3.0-2) were as follows:

Trace metals analyses were eliminated for the Post-Uprate period.

Stable isotope (carbon (13C), oxygen (18O), hydrogen (D), and strontium(87Sr/86Sr))

analyses were eliminated for the Post-Uprate period.

Cation and anion analyses with the exception of sodium and chloride, were reduced from quarterly to semi-annually.

Sampling logs from June 2013 to March 2014 are provided in Appendix G. Most of the samples were analyzed by TestAmerica; however, tritium analysis was conducted by the USGS Tritium Laboratory. Details of the analytical methodologies for each analyte are provided in the project QAPP.

For the Post-Uprate, several analytical methods were changed because of interference that impacted result accuracy. For example, several ions have been problematic during analysis because of their low concentrations compared to the other peaks in the chromatogram. In the Post-Uprate, fluoride was switched to a probe analysis method due to frequent interference by the chloride peak. Sulfide was another method that was switched because of frequent non-detect values.

FPL Turkey Point Annual Post-Uprate Monitoring Report for Units 3 & 4 Uprate Project - August 2014 Section 3 During the Post-Uprate, it was determined that bicarbonate alkalinity was being calculated as mg/L as CaCO3 instead of mg/L as HCO3 per the Monitoring Plan. This laboratory calculation affects all values after September 2010; therefore, a correction factor of x1.22 will have to be applied to datasets after September 2010 to adjust results to report as mg/L as HCO3 (TestAmerica 2014).

3.1 GROUNDWATER QUALITY 3.1.1 Sample Collection and Analysis Groundwater samples were collected in accordance with the QAPP and based on FDEP Standard Operating Procedures (SOPs). Figure 3.1-1 shows a typical setup for the groundwater sampling.

Groundwater and surface water sampling logs from June 2013 to March 2014 are included in Appendix G of this report.

3.1.2 Results and Discussion Values in most of the wells have been fairly consistent in the Post-Uprate period and are similar in range to values observed during the Pre-Uprate period. Tables 3.1-1 through 3.1-4 provide a summary of the groundwater analytical results from the June 2013 through May 2014 sampling events. Results for the sampling events from the historical monitoring wells L-3, L-5, G-21, G-28, and G-35 during the same time period are provided in Tables 3.1-5 through 3.1-8. DUS Reports for all events are provided in Appendix H, and the detailed Level IV laboratory reports from TestAmerica are included in Appendix I. A summary of the ionic ranges Pre- and Post-Uprate is provided in Table 3.1-9.

The only notable changes observed were in TPGW-10D and TPGW-7D, and to a lesser degree to TPGW-11D in this Post-Uprate period. Both TPGW-10D and TPGW-7D had higher specific conductance and ionic concentrations relative to the Pre-Uprate period; the ionic increases in TPGW-10D were observed starting in September 2012 during the Interim Operating Period while the increase in TPGW-7D started in September 2013. This is supported by automated monitoring specific conductance values as shown in Figures 2.1-8 and 2.1-11. A slight ionic and specific conductance increase was also observed in TPGW-11D starting in the Interim Operating Period. The more saline water at TPGW-10D and TPGW-11D remain confined at depth and do not appear to be migrating into the upwards. Further assessment of the water in TPGW-7D is pending as tritium data from June 2013 to March 2014 are still being analyzed by the USGS.

3.1.2.1 Chloride, Sodium, and Specific Conductance Figures 3.1-2, 3.1-3, and 3.1-4, and Tables 3.1-1 to 3.1-4 show the chloride, sodium, and specific conductance values for the sampling events from June 2013 through March 2014. There was some seasonal variation but lower than that observed in the surface waters. Within a well cluster, the lowest sodium and chloride values were generally observed in the shallow wells; the only exception to this was at TPGW-13 where the intermediate and deep wells had consistently lower 3-2

FPL Turkey Point Annual Post-Uprate Monitoring Report for Units 3 & 4 Uprate Project - August 2014 Section 3 values than the shallow well over the monitoring period (Figures 3.1-2 and -3). The new monitoring wells, which were cased at specific intervals, also had lower variability compared to the historical monitoring wells, which are open throughout most of the well length.

Chloride values in TPGW-13 during the Post-Uprate period were similar to the values during the Pre-Uprate period (Table 3.1-9). Similarly, the ranges observed in the Biscayne Bay wells (TPGW-10, TPGW-11, and TPGW-14) showed the same Post-Uprate patterns with the exception of TPGW-10D and, to a lesser extent, TPGW-11D (Table 3.1-9). Both wells showed an increase in chloride concentrations commensurate with the specific conductance increase observed in the automated and other ionic data. During the Pre-Uprate period through February 2012, TPGW-10D chloride values were reflective of marine waters, but starting from September 2012 during the Interim Operating Period, this well now exhibits a mix of marine and some CCS water.

TPGW-11 during the Pre-Uprate had slightly higher chloride values in the intermediate and deep wells relative to the shallow well; the values in the intermediate well have not changed during the Post-Uprate, but chloride concentrations have been increasing in TPGW-11D starting in March 2013 during the Interim Operating Period and into the Post-Uprate.

Terrestrial wells around and to the west of the CCS (TPGW-1 through TPGW-6, TPGW-12, TPGW-L3, TPGW-L5, TPGW-G21, TPGW-G28, and TPGW-G35) had vertical and spatial Post-Uprate sodium, chloride, and specific conductance values similar to those observed during the Pre-Uprate period (Figures 3.1-5, 3.1-6, 3.1-7 and 3.1-8). The range of values observed in the shallow wells or 18 ft depth (in the case of the historical wells) continued to be lower than the samples from depth due to the fresher water lens that overlies the area west of the CCS. This freshwater zone is evident in the upper 20 to 40 ft of the aquifer and increases in depth towards the west; this is supported by the annual USGS induction log results (Appendix E) from the dry season (i.e., April 2014).

Temporally, the chloride, sodium, and specific conductance ranges across the landscape in the shallow wells were not significantly different in the four quarters of Post-Uprate compared to the seven Pre-Uprate events (chloride: F1,150=0.06, P=0.804; sodium: F1,150=0.47, P=0.504; specific conductance: F1,150=1.23, P=0.287). Wells TPGW-7, TPGW-8, and TPGW-9, farthest away from the CCS, were fresh (i.e., less than 500 milligrams per liter [mg/L] chloride and less than 1,275 µS/cm specific conductance) at all depths during the Pre-Uprate period and most of the wells remain fresh during the Post-Uprate. The only exception was TPGW-7D, which showed an increase in chloride, sodium, and specific conductance levels starting in September 2013.

Further assessment of the water in TPGW-7D cannot be conducted as tritium data from June 2013 onwards is still pending.

3.1.2.2 Ions Select ions (calcium, magnesium, potassium, boron, strontium, bromide, fluoride, and sulfate) analysis was reduced to semi-annually beginning in June 2013; sodium and chloride analyses were to continue on a quarterly basis. For the Post-Uprate period, data for both September 2013 and March 2014 are compared against the Pre-Uprate period (quarterly from June 2010 to December 2011). Ionic concentrations at the TPGW sites (Tables 3.1-1 to 3.1-4) appeared to 3-3

FPL Turkey Point Annual Post-Uprate Monitoring Report for Units 3 & 4 Uprate Project - August 2014 Section 3 correspond with specific conductance values in most of the wells and varied seasonally, i.e.,

lower in the wet season (September 2013) and higher in the dry season (March 2014).

Tri-linear diagrams comparing the Post-Uprate to the Pre-Uprate indicated very little average difference in the overall patterns (Figure 3.1-9). Freshwater sites had low concentrations of ions, while marine-influenced sites generally had higher values. The highest values were observed at TPGW-13 (Table 3.1-9); the ionic chemistry of this site based on the tri-linear diagram showed that for both the Post-Uprate and Pre-Uprate, this station had similar chemistry (i.e., overlapping on the tri-linear diagram) to the marine stations (Figure 3.1-9). The range of values also remained consistent for most of the sites during the Post-Uprate period and Post-Uprate values were consistent with the Pre-Uprate values; the only exceptions were TPGW-7D, TPGW-10D and TPGW-11D which were higher, reflecting the increase in specific conductance observed.

TPGW-8S continues to have high pH (10.77 to 11.86) and high alkalinity (182 to 430 mg/L) in the Post-Uprate, similar to the Pre-Uprate period. The patterns are only observed at this depth at this location, and the alkalinity is mostly due to hydroxide ions indicating a stronger base than found under natural conditions.

3.1.2.4 Nutrients Tables 3.1-2 and 3.1-4 show the nutrient results for the September 2013 and March 2014 sampling events, while Figure 3.1-10 summarizes the data and compares it to the Pre-Uprate range. For the five groundwater sites monitored, nitrogen occurs primarily as ammonia (greater than 60% of total nitrogen [TN]) across the landscape at all depths. The majority (greater than 90%) of the ammonia was in the form of ammonium and this observation was consistent for both the Post-Uprate and Pre-Uprate periods.

Although TN was slightly higher in September 2013 relative to March 2014, both events were within range of the Pre-Uprate data. Nitrogen concentrations were lowest at TPGW-10 and TPGW-14, followed by TPGW-1, TPGW-2, and TPGW-13. Similar to specific conductance, wells at depth generally had higher nutrient concentrations compared to the shallower wells; the only exception was TPGW-13 where the nutrients in the shallow well were either similar to or higher than the wells at depth for both the Pre- and the Post-Uprate periods.

A one-time collection of nutrient data from TPGW-4 through TPGW-9 indicated that the wells were similar to the data from TPGW-10. Wells TPGW-5 and TPGW-7 showed a gradient of increasing TN with depth. TPGW-8S had high ammonia and unionized ammonia as pH>8 will increase the availability of ammonia. Consequently, this high ammonia contributes to high TKN that results in elevated TN. This result may be an artifact of the unusual chemistry of this site and not an influence from the CCS.

Although TP was slightly higher in September 2013 relative to March 2014, overall, average TP during the Post-Uprate (0.038 +/- 0.002 mg/L) in TPGW-13 was lower than in the Pre-Uprate (0.050 +/- 0.006 mg/L; F1,74=40.58; P<0.001). This Pre-Post Uprate trend was also observed in the other groundwater stations.

FPL Turkey Point Annual Post-Uprate Monitoring Report for Units 3 & 4 Uprate Project - August 2014 Section 3 3.2 SURFACE WATER QUALITY 3.2.1 Sample Collection and Analysis Surface water data were initially collected from 19 locations (33 sites), but this was reduced to 16 locations (27 sites) after Agency review in June 2013 (SFWMD 2013a). A list of the sites eliminated is shown in Section 1. The sampling methods follow Florida Department of Environmental Protection protocols and remain the same as described in the Comprehensive Pre-Uprate Report (FPL 2012); samples are still being collected from 1 ft below the surface (T) and 1 ft above the bottom (B) unless the water depths in the CCS, ID, or canals were less than 3 ft. In Biscayne Bay, regardless of water depth, all samples were collected at depth.

3.2.2 Results and Discussion Tables 3.2-1 through 3.2-4 provide a summary of the surface water analytical results from June 2013 through May 2014. DUS Reports for each event are provided in Appendix H and detailed Level IV laboratory reports from TestAmerica are included in Appendix I. Additionally, the stations have been grouped based on their general characteristics and location, and Table 3.2-5 shows the minimum, maximum, average and standard deviation of these water bodies from June 2013 to March 2014, unless otherwise explicitly stated.

3.2.2.1 Chloride, Sodium, and Specific Conductance Figures 3.2-1, 3.2-2, and 3.2-3 detail chloride, sodium, and specific conductance values for all surface water stations for the June 2013 through March 2014 sampling events. The values observed were highly dependent on the water body, water management practices, and seasonal conditions. Values were generally lower during the wet season and higher during the dry season.

Surface waters with chloride concentrations greater than 1,500 mg/L are defined as predominantly marine, while those with less than 1,500 mg/L are defined as predominantly fresh (F.A.C.62-302.200). The Class II/III criteria for specific conductance in freshwater (excluding consideration of background values) is less than 1,275 µS/cm while values higher than 1,275

µS/cm in a coastal environment are often viewed as potentially having some marine influence.

The highest chloride values were observed in the CCS (27,000 to 49,800 mg/L), with the highest values being observed in March 2014 and the lowest values in June 2013. The values observed during the Post-Uprate (average: 39,008 mg/L) were higher than the Pre-Uprate (average: 34,114 mg/L); however, none of the other surrounding water bodies showed a similar increase. Average chloride levels in other canals, as well as in Biscayne Bay, were lower in the Post-Uprate relative to the Pre-Uprate (which encompassed a drought in the spring of 2011).

Biscayne Bay values were influenced by rainfall, proximity to canal inputs, and water depth.

Consequently, TPBBSW-3 and TPBBSW-4 are more variable compared to TPBBSW-5, which is 3-5

FPL Turkey Point Annual Post-Uprate Monitoring Report for Units 3 & 4 Uprate Project - August 2014 Section 3 farther south, in deeper water, and not near any inlets to allow exchange with the Atlantic Ocean.

The values in TPBBSW-4 are comparable to TPSWC-5, which is located in the Card Sound Canal, just south of the CCS. This station is connected to the Bay and values reflect the conditions in the Bay. Unlike the Pre-Uprate period where differences of up to 8,000 mg/L were observed between the top and bottom at this location, chloride differences during the Post-Uprate were limited (maximum difference of 1,400 mg/L higher at depth in June 2013).

TPSWC-1, TPSWC-2, TPSWC-3, and TPSWC-6 are all considered freshwater stations based on the average chloride, sodium, and specific conductance values for the Post-Uprate period.

However, during the dry season, the bottom of these stations can have slightly higher values of chloride and sodium compared to the surface. The sodium values during the Post-Uprate were however, lower than the Pre-Uprate values (F1,336=5.44; P=0.030) while the Post-Uprate chloride values were not significantly different than the Pre-Uprate (F1,335=0.94; P=0.342). The L-31E west of CCS is not a canal that is actively managed by the SFWMD; consequently, the values observed in TPSWC-1, TPSWC-2, and TPSWC-3 on this canal are primarily driven by rainfall and runoff from the Model Lands marsh. Sites at the top also tended to be fresher compared to depth. A similar pattern was observed at TPSWC-6 which is located on the Card Sound Road canal and is viewed as a control site for the CCS stations. Differences between the top and bottom sites were greatest at TPSWC-3, which was noticeably higher at the bottom relative to the top during December 2013.

Vertical differences were also observed at TPSWID-1, TPSWID-2, and TPSWID-3 during the Post-Uprate period. The chloride concentrations varied seasonally and also with pumping of the ID. The stations were fresh for most of the year (i.e., less than 1,500 mg/L chloride), but became saline at depth with pumping and limited rainfall. Concentrations would then slowly decline with the onset of the rains in the wet season. None of the values observed Post-Uprate, however, even approached the values observed during the 2011 drought that was part of the Pre-Uprate period.

Top and bottom station differences were also observed at TPSWC-4 even though this site is only about 5 ft deep. TPSWC-4 is located along the S-20 canal southwest of the CCS. In January 2014, a weir structure was installed downstream of this site, which resulted in a reduction of flow from the canal into Biscayne Bay. This resulted in a decrease in specific conductance, chloride, and salinity in March 2014 when there would normally have been an increase due to the dry season (as observed in the Pre-Uprate period).

3.2.2.2 Ions and Silica The seasonal and spatial ion concentrations (calcium, magnesium, potassium, boron, strontium, bromide, fluoride, and sulfate) in the surface water stations followed the observations noted above for sodium and chloride. Ion concentrations in the CCS were higher than those of Biscayne Bay (Table 3.2-5), while the TPSWC and TPSWID ions were generally lower in concentration but varied seasonally with freshwater influence.

3-6

FPL Turkey Point Annual Post-Uprate Monitoring Report for Units 3 & 4 Uprate Project - August 2014 Section 3 Ionic concentrations in the CCS during the Post-Uprate period were generally higher than during the Pre-Uprate years, but there were no differences between the Pre- and the Post-Uprate time periods for any of the other canals or Biscayne Bay. The values in the Bay were similar in range to the values observed by Reich et al. (2006). The tri-linear diagram (Figure 3.2-4) for the average Post-Uprate period showed clear separation between the different water bodies, with TPSWC-6 and the marine/CCS stations forming the endpoints along a spectrum of ionic concentrations. TPSWC-6 was distinct from the freshwater L-31E stations (TPSWC-1, TPSWC-2, and TPSWC-3) and the ID stations, but the marine-influenced (all TPBBSW, all TPSWCCS, TPSWC-4, and TPSWC-5) and CCS stations were ionically similar. These clusters remained consistent between the Post- and Pre-Uprate time periods.

During the Post-Uprate, silica was measured only in the CCS, twice a year at six of the seven original sites (TPSWCCS-6 eliminated). Silica concentrations in the Post-Uprate showed higher values in March 2014 compared to September 2013, and the Pre-Uprate period. Silica was 5.51

+/- 0.05 mg/L (average +/- standard error) in March 2014 but approximately half the concentration in September 2013 (2.65 +/- 0.03 mg/L); these values were also higher than the average (1.63 +/-

0.41 mg/L) observed during the Pre-Uprate period. These silica values are within the range observed by the FIU Water Quality monitoring network across Florida Bay (0.000 to 5.731 mg/L) and Biscayne Bay (0.000 to 1.972 mg/L) (Boyer and Briceno 2008).

3.2.2.3 Nutrients For all statistical analyses of CCS nutrients, all data from the CCS sites where surface water sampling was discontinued (TPSWCCS-4B, -5B, -6T, and -6B) were removed from the analyses.

Figure 3.2-5 shows the distribution of nutrient concentration in the surface water for September 2013 and March 2014. The most notable change was the increase in the TN within the CCS in the Post-Uprate period compared to the Pre-Uprate period (F1,28=311.44; P<0.001). As almost all the TN in the monitoring stations was from TKN, this change was attributable to the increase of TKN in the Post-Uprate period (13.28 +/- 0.76 mg/L) compared to the Pre-Uprate period (2.01

+/- 0.05 mg/L) in the CCS (Figure 3.2-6). TKN is sum of ammonia and organic nitrogen (amino acids, urea). These increases in the CCS are from an increase in organic nitrogen sources as the ammonia contribution to the TKN of these samples were only about 1% for both sampling events. Although TKN values were approximately 15 mg/L in the CCS in September 2013, these values had decreased approximately 30% to about 11 mg/L by March 2014.

In the other water bodies, ammonia contribution varied seasonally (i.e., lower in September 2013 relative to March 2014), as well as spatially (the Bay was less than the surface water canal or the ID sites). Ammonia values in the ID and the surface water canals were higher than both the CCS or in Biscayne Bay. This is not unexpected as these canals have biological activity and limited turnover of water most of the year (Figure 3.2-6). The Post-Uprate ammonia patterns were consistent with the Pre-Uprate values (Table 3.2-5), indicating little temporal variability.

Similarly, the patterns of the other nitrogen species (i.e., nitrate/nitrite, unionized ammonia, ammonium) did not vary between the Pre- and Post-Uprate either.

3-7

FPL Turkey Point Annual Post-Uprate Monitoring Report for Units 3 & 4 Uprate Project - August 2014 Section 3 Total phosphorus is higher in the Post-Uprate (0.048 +/- 0.006 mg/L) compared to the Pre-Uprate (0.028 +/- 0.003 mg/L) within the CCS (F1,29=6.73; P=0.050). These differences are not unexpected given the increase in TN between the same time periods. Both TN and TP are key biological nutrients so an increase in TN is often accompanied by an increase in TP (Quiros 2002). Values in the other water bodies however remained consistent and did not show a similar Pre-Post Uprate increase over the monitoring duration.

3. QUARTERLY GROUNDWATER AND SURFACE WATER SAMPLING The Monitoring Plan (SFWMD 2009a) and the QAPP (FPL 2013b) for this project outline the locations and analytes for the groundwater and surface water sampling and the analyses for quarterly and semi-annual events. Each groundwater location is a cluster of three wells at different depth intervals. The groundwater wells are designated by depth and are defined as S for shallow wells (-15.3 to -34.7 ft North American Vertical Datum of 1988 [NAVD 88] to bottom of screen elevation), M for intermediate wells (-32.8 to -85.7 ft NAVD 88 to bottom of screen elevation), and D for deep wells (-46.4 to -122.2 ft NAVD 88 to bottom of screen elevation). Surface water samples are also designated by depth, i.e., T for top (1 ft below surface) and B for bottom (1 ft above bottom). Samples also were collected from several of the historical wells that have been monitored as part of the ID operations. Since the historical wells (L-3, L-5, G-21, G-28, and G-35) are screened across the entire well depth, samples were collected from two depths (18 ft and 58 ft below top of casing).

From June 2010 to May 2013, samples were collected quarterly at specified locations and were analyzed for the parameters as required in the Monitoring Plan. In June 2013, after review by the Agencies, several sites and parameters were dropped from the sampling. Three sites (TPBBSW-1B, TPBBSW-2B, and TPSWCCS-6 [B and T]) and two bottom stations (TPSWCCS-4B and TPSWCCS-5B) were eliminated. Per the Agencies, the data reductions (Tables 3.0-1 and 3.0-2) were as follows:

Trace metals analyses were eliminated for the Post-Uprate period.

Stable isotope (carbon (13C), oxygen (18O), hydrogen (D), and strontium(87Sr/86Sr))

analyses were eliminated for the Post-Uprate period.

Cation and anion analyses with the exception of sodium and chloride, were reduced from quarterly to semi-annually.

Sampling logs from June 2013 to March 2014 are provided in Appendix G. Most of the samples were analyzed by TestAmerica; however, tritium analysis was conducted by the USGS Tritium Laboratory. Details of the analytical methodologies for each analyte are provided in the project QAPP.

For the Post-Uprate, several analytical methods were changed because of interference that impacted result accuracy. For example, several ions have been problematic during analysis because of their low concentrations compared to the other peaks in the chromatogram. In the Post-Uprate, fluoride was switched to a probe analysis method due to frequent interference by the chloride peak. Sulfide was another method that was switched because of frequent non-detect values.

3-1

FPL Turkey Point Annual Post-Uprate Monitoring Report for Units 3 & 4 Uprate Project - August 2014 Section 3 During the Post-Uprate, it was determined that bicarbonate alkalinity was being calculated as mg/L as CaCO3 instead of mg/L as HCO3 per the Monitoring Plan. This laboratory calculation affects all values after September 2010; therefore, a correction factor of x1.22 will have to be applied to datasets after September 2010 to adjust results to report as mg/L as HCO3 (TestAmerica 2014).

3.1 GROUNDWATER QUALITY 3.1.1 Sample Collection and Analysis Groundwater samples were collected in accordance with the QAPP and based on FDEP Standard Operating Procedures (SOPs). Figure 3.1-1 shows a typical setup for the groundwater sampling.

Groundwater and surface water sampling logs from June 2013 to March 2014 are included in Appendix G of this report.

3.1.2 Results and Discussion Values in most of the wells have been fairly consistent in the Post-Uprate period and are similar in range to values observed during the Pre-Uprate period. Tables 3.1-1 through 3.1-4 provide a summary of the groundwater analytical results from the June 2013 through May 2014 sampling events. Results for the sampling events from the historical monitoring wells L-3, L-5, G-21, G-28, and G-35 during the same time period are provided in Tables 3.1-5 through 3.1-8. DUS Reports for all events are provided in Appendix H, and the detailed Level IV laboratory reports from TestAmerica are included in Appendix I. A summary of the ionic ranges Pre- and Post-Uprate is provided in Table 3.1-9.

The only notable changes observed were in TPGW-10D and TPGW-7D, and to a lesser degree to TPGW-11D in this Post-Uprate period. Both TPGW-10D and TPGW-7D had higher specific conductance and ionic concentrations relative to the Pre-Uprate period; the ionic increases in TPGW-10D were observed starting in September 2012 during the Interim Operating Period while the increase in TPGW-7D started in September 2013. This is supported by automated monitoring specific conductance values as shown in Figures 2.1-8 and 2.1-11. A slight ionic and specific conductance increase was also observed in TPGW-11D starting in the Interim Operating Period. The more saline water at TPGW-10D and TPGW-11D remain confined at depth and do not appear to be migrating into the upwards. Further assessment of the water in TPGW-7D is pending as tritium data from June 2013 to March 2014 are still being analyzed by the USGS.

3.1.2.1 Chloride, Sodium, and Specific Conductance Figures 3.1-2, 3.1-3, and 3.1-4, and Tables 3.1-1 to 3.1-4 show the chloride, sodium, and specific conductance values for the sampling events from June 2013 through March 2014. There was some seasonal variation but lower than that observed in the surface waters. Within a well cluster, the lowest sodium and chloride values were generally observed in the shallow wells; the only exception to this was at TPGW-13 where the intermediate and deep wells had consistently lower 3-2

FPL Turkey Point Annual Post-Uprate Monitoring Report for Units 3 & 4 Uprate Project - August 2014 Section 3 values than the shallow well over the monitoring period (Figures 3.1-2 and -3). The new monitoring wells, which were cased at specific intervals, also had lower variability compared to the historical monitoring wells, which are open throughout most of the well length.

Chloride values in TPGW-13 during the Post-Uprate period were similar to the values during the Pre-Uprate period (Table 3.1-9). Similarly, the ranges observed in the Biscayne Bay wells (TPGW-10, TPGW-11, and TPGW-14) showed the same Post-Uprate patterns with the exception of TPGW-10D and, to a lesser extent, TPGW-11D (Table 3.1-9). Both wells showed an increase in chloride concentrations commensurate with the specific conductance increase observed in the automated and other ionic data. During the Pre-Uprate period through February 2012, TPGW-10D chloride values were reflective of marine waters, but starting from September 2012 during the Interim Operating Period, this well now exhibits a mix of marine and some CCS water.

TPGW-11 during the Pre-Uprate had slightly higher chloride values in the intermediate and deep wells relative to the shallow well; the values in the intermediate well have not changed during the Post-Uprate, but chloride concentrations have been increasing in TPGW-11D starting in March 2013 during the Interim Operating Period and into the Post-Uprate.

Terrestrial wells around and to the west of the CCS (TPGW-1 through TPGW-6, TPGW-12, TPGW-L3, TPGW-L5, TPGW-G21, TPGW-G28, and TPGW-G35) had vertical and spatial Post-Uprate sodium, chloride, and specific conductance values similar to those observed during the Pre-Uprate period (Figures 3.1-5, 3.1-6, 3.1-7 and 3.1-8). The range of values observed in the shallow wells or 18 ft depth (in the case of the historical wells) continued to be lower than the samples from depth due to the fresher water lens that overlies the area west of the CCS. This freshwater zone is evident in the upper 20 to 40 ft of the aquifer and increases in depth towards the west; this is supported by the annual USGS induction log results (Appendix E) from the dry season (i.e., April 2014).

Temporally, the chloride, sodium, and specific conductance ranges across the landscape in the shallow wells were not significantly different in the four quarters of Post-Uprate compared to the seven Pre-Uprate events (chloride: F1,150=0.06, P=0.804; sodium: F1,150=0.47, P=0.504; specific conductance: F1,150=1.23, P=0.287). Wells TPGW-7, TPGW-8, and TPGW-9, farthest away from the CCS, were fresh (i.e., less than 500 milligrams per liter [mg/L] chloride and less than 1,275 µS/cm specific conductance) at all depths during the Pre-Uprate period and most of the wells remain fresh during the Post-Uprate. The only exception was TPGW-7D, which showed an increase in chloride, sodium, and specific conductance levels starting in September 2013.

Further assessment of the water in TPGW-7D cannot be conducted as tritium data from June 2013 onwards is still pending.

3.1.2.2 Ions Select ions (calcium, magnesium, potassium, boron, strontium, bromide, fluoride, and sulfate) analysis was reduced to semi-annually beginning in June 2013; sodium and chloride analyses were to continue on a quarterly basis. For the Post-Uprate period, data for both September 2013 and March 2014 are compared against the Pre-Uprate period (quarterly from June 2010 to December 2011). Ionic concentrations at the TPGW sites (Tables 3.1-1 to 3.1-4) appeared to 3-3

FPL Turkey Point Annual Post-Uprate Monitoring Report for Units 3 & 4 Uprate Project - August 2014 Section 3 correspond with specific conductance values in most of the wells and varied seasonally, i.e.,

lower in the wet season (September 2013) and higher in the dry season (March 2014).

Tri-linear diagrams comparing the Post-Uprate to the Pre-Uprate indicated very little average difference in the overall patterns (Figure 3.1-9). Freshwater sites had low concentrations of ions, while marine-influenced sites generally had higher values. The highest values were observed at TPGW-13 (Table 3.1-9); the ionic chemistry of this site based on the tri-linear diagram showed that for both the Post-Uprate and Pre-Uprate, this station had similar chemistry (i.e., overlapping on the tri-linear diagram) to the marine stations (Figure 3.1-9). The range of values also remained consistent for most of the sites during the Post-Uprate period and Post-Uprate values were consistent with the Pre-Uprate values; the only exceptions were TPGW-7D, TPGW-10D and TPGW-11D which were higher, reflecting the increase in specific conductance observed.

TPGW-8S continues to have high pH (10.77 to 11.86) and high alkalinity (182 to 430 mg/L) in the Post-Uprate, similar to the Pre-Uprate period. The patterns are only observed at this depth at this location, and the alkalinity is mostly due to hydroxide ions indicating a stronger base than found under natural conditions.

3.1.2.4 Nutrients Tables 3.1-2 and 3.1-4 show the nutrient results for the September 2013 and March 2014 sampling events, while Figure 3.1-10 summarizes the data and compares it to the Pre-Uprate range. For the five groundwater sites monitored, nitrogen occurs primarily as ammonia (greater than 60% of total nitrogen [TN]) across the landscape at all depths. The majority (greater than 90%) of the ammonia was in the form of ammonium and this observation was consistent for both the Post-Uprate and Pre-Uprate periods.

Although TN was slightly higher in September 2013 relative to March 2014, both events were within range of the Pre-Uprate data. Nitrogen concentrations were lowest at TPGW-10 and TPGW-14, followed by TPGW-1, TPGW-2, and TPGW-13. Similar to specific conductance, wells at depth generally had higher nutrient concentrations compared to the shallower wells; the only exception was TPGW-13 where the nutrients in the shallow well were either similar to or higher than the wells at depth for both the Pre- and the Post-Uprate periods.

A one-time collection of nutrient data from TPGW-4 through TPGW-9 indicated that the wells were similar to the data from TPGW-10. Wells TPGW-5 and TPGW-7 showed a gradient of increasing TN with depth. TPGW-8S had high ammonia and unionized ammonia as pH>8 will increase the availability of ammonia. Consequently, this high ammonia contributes to high TKN that results in elevated TN. This result may be an artifact of the unusual chemistry of this site and not an influence from the CCS.

Although TP was slightly higher in September 2013 relative to March 2014, overall, average TP during the Post-Uprate (0.038 +/- 0.002 mg/L) in TPGW-13 was lower than in the Pre-Uprate (0.050 +/- 0.006 mg/L; F1,74=40.58; P<0.001). This Pre-Post Uprate trend was also observed in the other groundwater stations.

FPL Turkey Point Annual Post-Uprate Monitoring Report for Units 3 & 4 Uprate Project - August 2014 Section 3 3.2 SURFACE WATER QUALITY 3.2.1 Sample Collection and Analysis Surface water data were initially collected from 19 locations (33 sites), but this was reduced to 16 locations (27 sites) after Agency review in June 2013 (SFWMD 2013a). A list of the sites eliminated is shown in Section 1. The sampling methods follow Florida Department of Environmental Protection protocols and remain the same as described in the Comprehensive Pre-Uprate Report (FPL 2012); samples are still being collected from 1 ft below the surface (T) and 1 ft above the bottom (B) unless the water depths in the CCS, ID, or canals were less than 3 ft. In Biscayne Bay, regardless of water depth, all samples were collected at depth.

3.2.2 Results and Discussion Tables 3.2-1 through 3.2-4 provide a summary of the surface water analytical results from June 2013 through May 2014. DUS Reports for each event are provided in Appendix H and detailed Level IV laboratory reports from TestAmerica are included in Appendix I. Additionally, the stations have been grouped based on their general characteristics and location, and Table 3.2-5 shows the minimum, maximum, average and standard deviation of these water bodies from June 2013 to March 2014, unless otherwise explicitly stated.

3.2.2.1 Chloride, Sodium, and Specific Conductance Figures 3.2-1, 3.2-2, and 3.2-3 detail chloride, sodium, and specific conductance values for all surface water stations for the June 2013 through March 2014 sampling events. The values observed were highly dependent on the water body, water management practices, and seasonal conditions. Values were generally lower during the wet season and higher during the dry season.

Surface waters with chloride concentrations greater than 1,500 mg/L are defined as predominantly marine, while those with less than 1,500 mg/L are defined as predominantly fresh (F.A.C.62-302.200). The Class II/III criteria for specific conductance in freshwater (excluding consideration of background values) is less than 1,275 µS/cm while values higher than 1,275

µS/cm in a coastal environment are often viewed as potentially having some marine influence.

The highest chloride values were observed in the CCS (27,000 to 49,800 mg/L), with the highest values being observed in March 2014 and the lowest values in June 2013. The values observed during the Post-Uprate (average: 39,008 mg/L) were higher than the Pre-Uprate (average: 34,114 mg/L); however, none of the other surrounding water bodies showed a similar increase. Average chloride levels in other canals, as well as in Biscayne Bay, were lower in the Post-Uprate relative to the Pre-Uprate (which encompassed a drought in the spring of 2011).

Biscayne Bay values were influenced by rainfall, proximity to canal inputs, and water depth.

Consequently, TPBBSW-3 and TPBBSW-4 are more variable compared to TPBBSW-5, which is 3-5

FPL Turkey Point Annual Post-Uprate Monitoring Report for Units 3 & 4 Uprate Project - August 2014 Section 3 farther south, in deeper water, and not near any inlets to allow exchange with the Atlantic Ocean.

The values in TPBBSW-4 are comparable to TPSWC-5, which is located in the Card Sound Canal, just south of the CCS. This station is connected to the Bay and values reflect the conditions in the Bay. Unlike the Pre-Uprate period where differences of up to 8,000 mg/L were observed between the top and bottom at this location, chloride differences during the Post-Uprate were limited (maximum difference of 1,400 mg/L higher at depth in June 2013).

TPSWC-1, TPSWC-2, TPSWC-3, and TPSWC-6 are all considered freshwater stations based on the average chloride, sodium, and specific conductance values for the Post-Uprate period.

However, during the dry season, the bottom of these stations can have slightly higher values of chloride and sodium compared to the surface. The sodium values during the Post-Uprate were however, lower than the Pre-Uprate values (F1,336=5.44; P=0.030) while the Post-Uprate chloride values were not significantly different than the Pre-Uprate (F1,335=0.94; P=0.342). The L-31E west of CCS is not a canal that is actively managed by the SFWMD; consequently, the values observed in TPSWC-1, TPSWC-2, and TPSWC-3 on this canal are primarily driven by rainfall and runoff from the Model Lands marsh. Sites at the top also tended to be fresher compared to depth. A similar pattern was observed at TPSWC-6 which is located on the Card Sound Road canal and is viewed as a control site for the CCS stations. Differences between the top and bottom sites were greatest at TPSWC-3, which was noticeably higher at the bottom relative to the top during December 2013.

Vertical differences were also observed at TPSWID-1, TPSWID-2, and TPSWID-3 during the Post-Uprate period. The chloride concentrations varied seasonally and also with pumping of the ID. The stations were fresh for most of the year (i.e., less than 1,500 mg/L chloride), but became saline at depth with pumping and limited rainfall. Concentrations would then slowly decline with the onset of the rains in the wet season. None of the values observed Post-Uprate, however, even approached the values observed during the 2011 drought that was part of the Pre-Uprate period.

Top and bottom station differences were also observed at TPSWC-4 even though this site is only about 5 ft deep. TPSWC-4 is located along the S-20 canal southwest of the CCS. In January 2014, a weir structure was installed downstream of this site, which resulted in a reduction of flow from the canal into Biscayne Bay. This resulted in a decrease in specific conductance, chloride, and salinity in March 2014 when there would normally have been an increase due to the dry season (as observed in the Pre-Uprate period).

3.2.2.2 Ions and Silica The seasonal and spatial ion concentrations (calcium, magnesium, potassium, boron, strontium, bromide, fluoride, and sulfate) in the surface water stations followed the observations noted above for sodium and chloride. Ion concentrations in the CCS were higher than those of Biscayne Bay (Table 3.2-5), while the TPSWC and TPSWID ions were generally lower in concentration but varied seasonally with freshwater influence.

3-6

FPL Turkey Point Annual Post-Uprate Monitoring Report for Units 3 & 4 Uprate Project - August 2014 Section 3 Ionic concentrations in the CCS during the Post-Uprate period were generally higher than during the Pre-Uprate years, but there were no differences between the Pre- and the Post-Uprate time periods for any of the other canals or Biscayne Bay. The values in the Bay were similar in range to the values observed by Reich et al. (2006). The tri-linear diagram (Figure 3.2-4) for the average Post-Uprate period showed clear separation between the different water bodies, with TPSWC-6 and the marine/CCS stations forming the endpoints along a spectrum of ionic concentrations. TPSWC-6 was distinct from the freshwater L-31E stations (TPSWC-1, TPSWC-2, and TPSWC-3) and the ID stations, but the marine-influenced (all TPBBSW, all TPSWCCS, TPSWC-4, and TPSWC-5) and CCS stations were ionically similar. These clusters remained consistent between the Post- and Pre-Uprate time periods.

During the Post-Uprate, silica was measured only in the CCS, twice a year at six of the seven original sites (TPSWCCS-6 eliminated). Silica concentrations in the Post-Uprate showed higher values in March 2014 compared to September 2013, and the Pre-Uprate period. Silica was 5.51

+/- 0.05 mg/L (average +/- standard error) in March 2014 but approximately half the concentration in September 2013 (2.65 +/- 0.03 mg/L); these values were also higher than the average (1.63 +/-

0.41 mg/L) observed during the Pre-Uprate period. These silica values are within the range observed by the FIU Water Quality monitoring network across Florida Bay (0.000 to 5.731 mg/L) and Biscayne Bay (0.000 to 1.972 mg/L) (Boyer and Briceno 2008).

3.2.2.3 Nutrients For all statistical analyses of CCS nutrients, all data from the CCS sites where surface water sampling was discontinued (TPSWCCS-4B, -5B, -6T, and -6B) were removed from the analyses.

Figure 3.2-5 shows the distribution of nutrient concentration in the surface water for September 2013 and March 2014. The most notable change was the increase in the TN within the CCS in the Post-Uprate period compared to the Pre-Uprate period (F1,28=311.44; P<0.001). As almost all the TN in the monitoring stations was from TKN, this change was attributable to the increase of TKN in the Post-Uprate period (13.28 +/- 0.76 mg/L) compared to the Pre-Uprate period (2.01

+/- 0.05 mg/L) in the CCS (Figure 3.2-6). TKN is sum of ammonia and organic nitrogen (amino acids, urea). These increases in the CCS are from an increase in organic nitrogen sources as the ammonia contribution to the TKN of these samples were only about 1% for both sampling events. Although TKN values were approximately 15 mg/L in the CCS in September 2013, these values had decreased approximately 30% to about 11 mg/L by March 2014.

In the other water bodies, ammonia contribution varied seasonally (i.e., lower in September 2013 relative to March 2014), as well as spatially (the Bay was less than the surface water canal or the ID sites). Ammonia values in the ID and the surface water canals were higher than both the CCS or in Biscayne Bay. This is not unexpected as these canals have biological activity and limited turnover of water most of the year (Figure 3.2-6). The Post-Uprate ammonia patterns were consistent with the Pre-Uprate values (Table 3.2-5), indicating little temporal variability.

Similarly, the patterns of the other nitrogen species (i.e., nitrate/nitrite, unionized ammonia, ammonium) did not vary between the Pre- and Post-Uprate either.

FPL Turkey Point Annual Post-Uprate Monitoring Report for Units 3 & 4 Uprate Project - August 2014 Section 3 Total phosphorus is higher in the Post-Uprate (0.048 +/- 0.006 mg/L) compared to the Pre-Uprate (0.028 +/- 0.003 mg/L) within the CCS (F1,29=6.73; P=0.050). These differences are not unexpected given the increase in TN between the same time periods. Both TN and TP are key biological nutrients so an increase in TN is often accompanied by an increase in TP (Quiros 2002). Values in the other water bodies however remained consistent and did not show a similar Pre-Post Uprate increase over the monitoring duration.
