Z-AREA GROUNDWATER MONITORING REPORT FOR 2005 (U)WSRC-TR-2005-00549 December 15, 2005 WSRC-TR-2005-00548PAGE2 of13 2 IntroductionIn accordance with SRS Z-Area Saltstone Industrial Solid Waste Permit, #025500-1603,wells ZBG-1, ZBG-1A and ZBG-2 are monitored for the parameters listed below:
pHSpecific Conductance
Water level Arsenic Antimony Barium Cadmium Chromium Lead Mercury Nitrate as Nitrogen Nitrite as Nitrogen
Selenium Silver Benzene and Toluene Radium 226 and 228 (sum)
Gross alpha Nonvolatile betaNew wells ZBG-3, ZBG-4 and ZBG-5 were also monitored although the permit has not yet been modified to include them. The wells (with the exception of ZGB-1A which was dry) were sampled twice during 2005. The first event was during first quarter and the second was spread over third and fourth quarters of due to sampling difficulties described below.The well sampling and analyses were conducted in accordance with Procedure Manual 3Q5, Hydrogeologic Data Collection except in the case of fourth quarter sampling at ZBG-3, ZBG-4and ZBG-5 where Hydrasleeve no-purge samplers were used. These wells are low producers with historically turbid samples that appear to yield anomalously high results for some metals.Confronted with the choice of not sampling at all or obtaining extremely turbid samples with a bailer, SRS opted to try the Hydrasleeve.The hydrasleeve has reduced the turbidity of most samples, however the turbidities are still high, and the results for most metals remain anomalously high.The analytical results are attached. The sampling did not reveal any evidence of a release from the Saltstone vaults. Flow directions and velocities were similar to those observed in past years.
Flow Direction and RatePotentiometric surface maps for the water table aquifer were constructed using first and third quarter data. Flow rate can be estimated using the following equation:Flow(ft/day)=Hydraulic Conductivity (ft/day) x dh(ft)Porosity (unitless) dl(ft)
WSRC-TR-2005-00548PAGE3 of13 3Where the hydraulic conductivity constant is 1.7 ft/day, the effective porosity value is 30 percent, the change in head is dh, and the horizontal distance is simply the distance between potentiometric contours (figures 1 and 2).For first quarter of 2004, the calculation is as follows:
1.7ft/day x12 ft = 0.052 ft/day or 18.98 ft/year0.301300 ftFor third quarter of 2004, the calculation is as follows:
1.7 ft/day x10 ft = 0.04 ft/day or 14.6 ft/year0.301400 ft Analytical resultsThe nitrate/nitrite results are by far the most important in determining whether or not an unexpected release is occurring. This is because nitrate is the most mobile constituent likely to leach from saltstone. As in past years, nitrate/nitrite was detected in the downgradient wells but higher concentrations were found in background well ZBG-1. Therefore the downgradient detections do not represent evidence of a release from the vaults. Results for several metals including barium and chromium remained elevated in some downgradient wells. As previously reported the wells were installed at the top of the watertable which resides in a clayey, silty formation that produces very little water. Changes in the sampling procedure have reduced the turbidity of samples from these wells, but the turbidity remains well above the ideal 10 NTU limit. Elevated results for metals are expected from turbid samples. Estimated concentrations (J qualified) were reported for arsenic and selenium in ZBG-4 and ZBG-5. Since the results are estimates well below the practical quantitation limits, no conclusions can be drawn about their meaning. However, it should be noted that there is no plausible mechanism for these metals to leach from saltstone and travel to the wells without being preceded by a plume of nitrate.Well ZBG-3 yielded a radium 226 result of 41.1 pCi/L on 3/30/05. This appears to have been the result of sampling or laboratory error. The sample taken on 8/31/05 yielded a more ordinary result of 1.79 pCi/L.
ConclusionsThe ZBG well series was sampled twice during 2004. ZBG-1A was dry. Flow rate and direction were consistent with historical patterns. The sampling did not reveal any evidence of a release from the saltstone vaults.
