WELL I N S T A L L A T I O M REPORT M O N I T O R I N G W E L L S I N THE P R O T E C T E D AREA

1. INTRODUCTION Brown and Caldwell has been contracted by Arizona Public Service Company (APS) to conduct environmental support and consdung services for the installation of monitoring wells as part of the corrective action associated with a Discharge of Non-hazardous Material reported on March 2,2006. The installation of the monitoring wells was part of the Work Plan provided in the 30-day follow-up report submitted April 3,2006. It has been developed in accordance with guidelines provided by the Arizona Department of Environmental Quahty (ADEQ and the Arizona Department of Water Resources (ADWR).

The work described herein is based on the Work Plan submitted by Brown and Cddwell onJune 30,2006, and the Work Plan Addendum submitted by Brown and Caldwell on September 12,2006.

1. Site Description and Background The Palo Verde Nudear Generating Station (PVNGS) began operations in 1985 and consists of an existing elearic genera- baseload plant ualrwng nuclear fission for generation of electrical power. PVNGS is a standardized wiple-unit nuclear power facility located near Wintersburg, Arizona, approximately 45 miles west of Phoenix (Figure 1). Low levels of tlitium were identified in water discovered in utility trenches associated with the reactor units. This discovery resulted in the need to investigate shallow groundwater conditions in the area of the units, Zones of shallow satmation are present within both the Upper Muvid Unit (UAU) and the upper portions of the Middle Fine-grained Unit 0 at the PVNGS. Fine-grained, low permeability material represented by the top of the MFU and he-grained subunits within the MFU appear to act as an aquiwd, M t i n g d o w n w d migration of groundwater. The aquitard at the top of the MFU can be correlated in geophysical logs and cross-sections throughout the Hassayampa groundwater basin. Overall, the MFU is characterized as massive, l a t e d y extensive layers of clays and silty clays interbedded with thinaer layers of clayey silt, clayey sand, and silty sand. The lower portion of the MFU includes the regionally extensive Palo Verde Clay, which is located at a depth ranging from approximately 175 to more than 200 feet below ground surface Ibgs) at the site, and ranges in thickness from 60 to 80 feet. All depths in this report are feet below ground surface unless noted otherwise. Based on evaluation of the borehole data for well APP-8, the depth to the top of the Palo Verde Clay near the reactor units was estimated at 200 feet.

Two saturated zones referred to as the Shallow Aquifer and the Palo Verde Clay Aquifer exist in the MFU overlying the Palo Verde Clay. Groundwater flow in the Shallow Aquifer appears to be radiating outward fmm the central portion of the WNGS site. In the central portion of the site, the lower portion of the UAU is saturated; at the margias of the site, static water levels are within the MFU. In the area of the reactor units, groundwater levels are in the MFU and available data indicates groundwater in the h4FU flows to the northwest.

The regional aquifer is located in the Lower Alluvial Unit beneath the Palo Verde Clay sub-unit.

Beneath the site, the regional aquifer is reported to be confined to semi-confined, with a potentiornettic surface that is above the contact between the coarser grained U U aquifer and the overlying MFU in many areas. Available water level elevation data &om the area south of the evaporation ponds indicates that the flow direction in the regional aquifer is to the southwest to west The direction of regional flow is amibuted to extensive pumping for irrigated agriculture that historically occurred near the Centennial Wash, southwest of PVNGS.

2. R A T I O N A L E A N D O B J E C T I V E S The objective of this work was to investigate the lateral and vertical extent of impacted areas at Units 2 and 3 where water impacted with tritium and volatile organic compounds WOCs) was detected and to evaluate similar areas In Unit 1, Dumg drilling activities, changes to the Work Plan dated June 30,2006 were submitted by Brown and Caldwell in an addendum dated September 12,2006. The addendum revised drilling methodology for some boring locations, which limited data collection objectives outlined in the otiginal work plan, Applicable objectives for field advities outlined in the work plan included:

0 Collect soil samples from and convert existing air-knifed boring dilled under Arizona Public Service (APS) oversight DJ monitoring wells.

D d l additional borings, collect soil samples, and convert to monitoring wells.

Submit soil samples for chemical and geotechnical analysis to assess zones of saturation and impacted areas.

Verify the depth to the base of flmaterial at Unit 3. Collect soil samples and subrnit for geotechnical analysis. Assess the spatial dismbution of zones of lugh or low permeability and evaluate their potential to be laterally continuous and potentially affect contaminant transport.

Verify that near-surface saturation observed at the Unit 3 RadWaste Yard is lirnited verticalIy and does not extend to the Shallow aquifer.

e Determine the depth to and elevation of the shallow aquifer in the vicinity of Unit 3.

0 Assess the extent of VOCs i n saturated soils at Unit 3 and identify whether or not VOCs are present at Units I and 2.

3. DRILLING FIELD ACTIVITIES Yellow Jacket Drilling was subconzvacted by Brown and Caldwell to drill the boreholes using the hollow-stem auger method, collect split-spoon samples, furnish and install the wells, devdop the wells, and install surfkce completions. In addition, Johnson Environmental Technologies, Inc. was subcontracted to collect shallow soil samples using a push rig, Activities performed prior to mobilization for field tasks included locating all subsurface utilities by PVNGS in areas where invasive activities (e.g., ddlmgj were performed. Notice of Intention POI) to D r d a Monitor/Piezometer Well forms were submitted to A D m and are included in Appendix A, During on-site field activities, WNGS safety procedures were followed. Standard Brown and Caldwell health and safety procedures and decontamination procedures were followed during drilling activities.

3.1 Drilling and Sampling The drilling program was conducted fiom September 5 to October 17,2006, and was performed in accordance with the procedures presented in the Work Plan dated June 30,2006 and associated Addendum to the Work Plan dated September 12,2006. Wells were installed in the t h e e units at Palo Verde (Figures 2 though 4). ADWR NOIs and Well DriUers Reports are presented in Appendix A, Due to errors on the Well D d e r Reports, Yellow Jacket will be resubmitting the reports with the corrected depth information, consistent with the well construction summary presented in Table I. Three welIs were installed in Unit 1, five wells were installed in Uait 2, and eight wells were installed in Uait 3. Ten of the wells were installed in existing soil borings that were advanced by the a i r - M e method by P W G S . One well was converted from an existing soil boring that was advanced using combined air-ktxfe and hollaw-stem auger drilling techniques, Because of the proximity of the well locations to sensitive piping, aIl borings were advanced at shallow depths using the air-ktxfe method. The &-knife method uses a considerable amount of water to aid the cutting of the soil. Aqueous samples were collected from the three water sources (one per unit) that were used during air-knihg.

Soil samples were collected using two techniques. Where appropriate, soil samples were collected using a split-spoon sampler conthing 6-inch long brass sleeves. Other shallow soil samples were collected by using a push rig and sampler lined with an acetate sleeve, Soil samples were described by a geologist in accordance with the Uniform Soil Classification System (USCS), as defined by the guideltnes contained in the American Society for Testing and Materials (ASTMj Standard Practice D 2488. Complete lithologic logs are presented in Appendix B. Soil samples that required shipment to a laboratory that could accept mixed waste were submitted to ACZ Laboratories (ACZ), ACZ analyzed the samples for metals including arsenic, barium, boron, cadmum, chromium, lead, mercury, potassium, selenium, sdver, and zinc. Soil and aqueous samples that could be released from the Protected Area (PA) were submitted to Transwest Geochem, Inc. (Transwest) to be analyzed for VOCs and metals. The laboratory reports are provided on disc in Appendix C. Thirty-two soil samples collected from the bo&gs of the PA wells were submitted to Terracon for geotechnical analysis i n d u d q moisture content and grain-size distribution. The geotechnical testing results are presented in Appendix D.

3.2 Lithology and Estimated Saturation Levels The lithology penetrated at each location was determined by evaluation of drilled cuttings and split-spoon samples. In general, engineered fill material composed of clayey sand was encountered from land surface to approximately 50 feet. Native soil composed of lean clay was encountered at approximately 50 feet Uae of dab contained on thii sheet is subjedb the l'mitedansq d % d in SediDn 6 af this b e n t .

3: Drillinu Field Activities Well Installation Re~ort:Monitoring Wells in the ProtectedArea Due to the fine-grained nature of the materials and the &e sample method, estimation of in-situ moisture content from split-spoon samples may not be considered accurate. Any saturation was ltkely driven-out during the advancement of the split-spoon sampler or push-rig sampler. The average volumetric moisture content of soil samples submitted to Temcon was 1I percent, 3.3 Well Installation and Development The wells were constructed with 4- or 6-inch diameter Schedule 40 polyvinyl chloride (PVC)casing and screen. The wells were screened with 0.020-inch wide slotted screen. No. 8-22 silica sand was installed from the bottom of the screen to approximately 2 feet above the top of screen. A 2- to Cfoot thick seal of bentonite chips was installed overIpg the silica sand. The w d was sealed with cement-bentonitegrout to the ground surface; the well was covered with a traffic-rated well monument. W ell construction diagrams are presented on Figures S through 20 and are summarized in Table 1.

Well development was conducted, to the extent possible, by bahtg the wells to remove sediment from the well casing, Water quality parameters were not collected during dwelopment, Water generated during well development was managed by PVNGS.

3.4 Groundwater Sampling Groundwater samples were collected on December 13 and 20,2006 from the PA wells. Prior to purg~ng,the depth to water in the wells was measured. The data is presented in Table 2. The wells were purged using disposable bailers.

Groundwater samples were collected from the followingw d s after purging and submitted m PV Central Laboratory for tritium analysis and Severn Trent Laboratories (STL) in Denver, Colorado, for the other analyses.

U2-HOa U2-Hob (a duplicate sample also was collected from this well)

U3-HOa

  • U3-Hob
  • U3-Hfl
  • U3-Hlb
  • U3-H5b The analyses requested were consistent with those listed in the Work Plan and included the following:
  • VOCs using U.S. Endronmental Protection Agency (USEPA) Test Method 8260B;
  • Tritium using USEPA Test Method 906.

Samples that were characterized as mixed waste due to the presence of tritium and/or gamma radioactive compounds were not submitted for stable isotopes @e.,0 1 8 and deuterium) because PVNGS was unable to identify a stable isotope laboratory that possessed a licensed to accept mixed waste.

3: Drillinu Field Activities Well Installation Re~ort:Monitoring Wells in the ProtectedAraa 3.5 Transducer Installation Pressure transducers were installed in the PA wells on November 16,2006 to monitor long-term water 1 4 s .

Level Troll 500 wansducers (manufactured by the In-Situ Company) were installed in each well as summarized in Table 2.

The transducers were programmed to collect water level data every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> for the long-term monitoring Program.

WELL I N S T A L L A T I O N R E P O R T M O N I T O R I N G WELLS I N THE P R O T E C T E D A R E A 4 . SOIL AND GROUNDWATER TESTING RESULTS Soil and groundwater samples were collected as indicated in the Work Plan dated June 30,2006. Soil samples were collected dutlllg the drilling program and submitted to Terracon for geotechnical analysis of grain-she distribution and moisture content and to STL and ACZ for analytical testing for VOCs and select metals.

Groundwater samples were collected with disposable bailers after the wells were purged; samples were submitted to STL for analysis.

4.1 Soil Geotechnical Results SoiI samples submitted for geotechmcal d y s i s were selected based on the results of the lithology evaluated in the field. Soil geotechnical results are summarized in Table 3, the laboratory reports are presented in Appendh D.

Due to the drive sample method, measured moisture values are likely lower than the undisturbed aquifer deposits. Therefore, strict analysis of zones of saturation cannot be determined based on the soil moisture data. Additiody, water introduced during air-knifing may have affected the results. However, grain-size analysis results provide an estimation of hydraulic conductivity. Based on the geotechnical data for U3-H7, there is a layer of lower permeability between 15 and 35 feet bgs, and increased hydraulic conductivity below 40 feet bgs. As summarized in Table 3, the moisture content results for U3-H7 are lugher at 15 feet bgs than for deeper samples.

4.2 Soil Analytical Results Soil samples were submitted for analysis of VOCs and metals including arsenic, b k u m , boron, cadmium, chromium, lead, mercury, potassium, selenium, silver, and zinc. Laboratory results indicate that all VOCs tested were below the detection limits of the instrument. Chloroform detected in the soil sample for U2-H7-45 (0,077mg/kg) is likely associated with the facility supplied water used during air-knifing. The on-site water was tested for V0Cs and chloroform was detected at a concentration of 0.79 micrograms per liter (Itg/L).

Chloroform detected in the domestic water supply is most likely a chlorination by-product from the disinfection process. The following metals were detected: arsenic, barium, boron, chromium, potassium, and zinc. The concentrations of these metals in the soil were below their respective residential soil remediation levels @-SRL) except for arsenic (arsecic R-SRL equals 10.0 milligrams per kilogram [mg/kgl). The arsenic concentration in the 50-foot sample collected from the borehole for well U2-H7 was reported at 14 mg/kg.

This result is consistent with arsenic soil sample results for APP-10 and APP-11, which ranged from non-detect to 11 mg/kg. The concenmtions for metals in soil are summarized in Table 4a through 4c and analytical laboratory reports are presented in Appendix C.

4.3 Groundwater Sampling Results Results for groundwater samples collected in December 2006 indicated VOCs were detected ie three of the groundwater samples, One detection of tetrachloroethene (PCE) exceeded the Aquifer Water Quality Standard (AWQS) of 5 p.g/L. Several inorganic compounds indudmg arsenic, barium, boron, calcium, chromium, chloride, fluoride, nitrate-nitrite (as nitrogen), potassium, sodium, and sulfate were reported above the detection limits. Arsenic, chromium, fluoride, lead, nickel, and nitrate (as nitrogen) were detected at concentrations above AWQS.

4: Soil and Groundwater Testinu Results Well Installation Re~ort:Monitorina Wells in the ProtectedArea Some VOCs (1,1,1 -trichloroethane, 1,l -dichloroethane, chloroform, PCE, total trihalomethenes, ks dichloroethene, and toluene) were detected at concentrations below their respective AWQS in three monitoihg wells (U2-HOa, U2-H0a, and U3-H5b). PCE was detected above the AWQS (5 pg/L) in U3-HOa (9.4 pg/L).

As desctibed in the memo &om APS to ADEQ dated December 15,2006, VOCs detected in the original test hole samples may have been associated with solvent cleaning of the buried pipe in the area prior to application of protective wrapping.

Arsenic was detected in six wells at concentrations ranging between 17 and 39 ILgIL, which are all above the AWQS of 10 pg/L. Chromium was detected in one well (U2-Hob) above the AWQS of 100 mg/L, at a concentration of 160 pg/L; however, the duplicate result was 77 pg/L. Fluoride was detected in four wells, ranging from 4,4 to 11 mg/L. Lead was detected in one well ([42-Hob, 75 pg/L) above the AWQS of 50 pg/L; however, the duplicate result was 34 pg/L. Nickel was detected in one well (U2-Hob) above the AWQS of 100 P~/L,at a concentration of 120 pg/L; however, the duplicate result was 53 pg/L. Nitrate-nitrite was detected above the AWQS of I0 mg/L in one well (U3-H1b) at a concen~ationof 14 mg/L.

The difference in analytical results between the parent and duplicate samples for U2-Hob for chromium, lead, and nickel, is discussed in the case narrative of the laboratory analytical report Based on the case narrative and Brown and Caldwell's discussion with the laboratory, the difference in results for the above listed metals is due to the presence of sediments in the sample containers which contained preservatives. In acid preserved samples with high turbidity or sediments, artificially increased results can be caused by the dissociation of metals from the solid phase, Variation in the results is likely due to the variation in solid phase in the sample.

Groundwater analytical results are summarized in Table 5, the laboratory reports are presented in Appendix C.

4.4 Survey Data and Groundwater Flow Condition Water levels were measured in October 2006 prior to groundwater samplmg. Water elevation data and APS surveyed well coordinate data are summarized in Table 6. In each Unit the H7 well was drilled to approximately 50 feet deep to determine whether vertical migration has occurred. The deep monitoring wells in each unit (U1-H7, U2-H7, and U3-H7) were all dry in October 2006. Therefore, vertical migration appears to be limited.

5. S U M M A R Y In support of further delineation of tritium and VOCs impacted areas, held investigation activities were conducted between September and December 2006. This report summarizes the PA well installation field activities and analytical results. A total of 16 monitoring wells were installed either from existing borings or newly W e d locations. Three monitoring wells were installed near Unit I, five near Unit 2, and eight near Unit 3, Soil samples were collected aad submitted for g w t e h i c a l and chemical analysis. Soil moisture analytical results should be viewed as semi-quantitative due to the natural indination for the d d h g and sampling process to drive soil moisture out. Therefore, strict analysis of zones of saturation cannot be determined based on the soil moisture data. In each of the Units,native material was encountered at approximately 50 feet bgs. The monitoliag wells installed in each Unit to approximately 50 feet bgs (H7wells) did not have water and therefore it appears that vertical migration is limited.

Groundwater samples collened and analyzed for witium in December 2006 did not exceed the AWQS. Some metals and nitrate-nimte were detected above the AWQS but these are attributed to background concentrations and/or remnants from the former agriculmral operations. PCE was detected above the AWQS in one weII in Unit 3, Soil analyucal data indicate that there was one exceedance of the arsenic R-SRL.
