Title: H-Area Acid/Caustic Basin groundwater monitoring report. First quarter 1995

Abstract

During first quarter 1995, samples collected from the four HAC monitoring wells at the H-Area Acid/Caustic Basin were analyzed for selected heavy metals, herbicides/pesticides, indicator parameters, major ions, radionuclide indicators, and other constituents. Monitoring results that exceeded the final Primary Drinking Water Standards (PDWS) or the Savannah River Site (SRS) flagging criteria or turbidity standard during third quarter are the focus of this report. Tritium exceeded the final PDWS in all four HAC wells during first quarter 1995. Carbon tetrachloride exceeded the final PDWS in well HAC 4. Aluminum exceeded its Flag 2 criterion in all four HAC wells. Iron was elevated in wells HAC 2 and 3. Total organic halogens was elevated in well HAC 3. The HAC 3 sample also exceeded the SRS turbidity standard. Groundwater flow direction in the water table beneath the H-Area Acid/Caustic Basin was to the northwest during first quarter 1995. This data is consistent with previous quarters, when the flow direction has been to the northwest or the north- northwest.

  • During first quarter 1995, samples from the FAC monitoring wells at the F-Area Acid/Caustic Basin were collected and analyzed for herbicides/pesticides, indicator parameters, metals, nitrate, radionuclide indicators, volatile organic compounds, and other constituents. Piezometer FAC 5P and monitoring well FAC 6 were dry and could not be sampled. New monitoring wells FAC 9C, 10C, 11C, and 12C were completed in the Barnwell/McBean aquifer and were sampled for the first time during third quarter 1994 (first quarter 1995 is the third of four quarters of data required to support the closure of the basin). Analytical results that exceeded final Primary Drinkingmore » Water Standards (PDWS), other Savannah River Site (SRS) Flag 2 criteria, or the SRS turbidity standard of 50 NTU during the quarter were as follows: gross alpha exceeded the final PDWS and aluminum, iron, manganese, and total alpha-emitting radium exceeded the SRS Flag 2 criteria in one or more of the FAC wells. Turbidity exceeded the SRS standard (50 NTU) in wells FAC 3 and 11C. Groundwater flow direction and rate in the water table beneath the F-Area Acid/Caustic Basin were similar to past quarters.« less

  • During first quarter 1995, groundwater from the six PAC monitoring wells at the P-Area Acid/Caustic Basin was analyzed for herbicides/pesticides, indicator parameters, metals, nitrate, adionuclide indicators, and other constituents. Monitoring results that exceeded the final Primary Drinking Water Standards (PDWS) or the Savannah River Site (SRS) flagging criteria or turbidity standard during the quarter are discussed in this report. During first quarter 1995, no constituents exceeded the final PDWS. Aluminum exceeded its SRS Flag 2 criterion in all six PAC wells. Iron and manganese exceeded Flag 2 criteria in three wells, while turbidity was elevated in one well. Groundwater flowmore » direction and rate in the water table beneath the P-Area Acid/Caustic Basin were similar to past quarters.« less

  • During first quarter 1995, samples from the KAC monitoring wells at the K-Area Acid/Caustic Basin were collected and analyzed for herbicides/pesticides, indicator parameters, metals, nitrate, radionuclide indicators, and other constituents. Monitoring results that exceeded the final Primary Drinking Water Standards (PDWS), other Savannah River Site (SRS) Flag 2 criteria, or the SRS turbidity standard are provided in this report. No constituents exceeded the final PDWS in the KAC wells. Aluminum and iron exceeded other SRS flagging criteria in one or more of the downgradient wells. Groundwater flow direction and rate in the water table beneath the K- Area Acid/Caustic Basinmore » were similar to past quarters.« less

  • The four monitoring wells at the H-Area Acid/Caustic Basin are sampled quarterly as part of the Savannah River Site (SRS) Groundwater Monitoring Program and to comply with a consent decree signed May 26, 1988, by the US District Court (District of South Carolina, Aiken Division). During second quarter 1995, groundwater from the HAC wells was analyzed for selected heavy metals, herbicides/pesticides, indicator parameters, major ions, radionuclide indicators, and other constituents. Monitoring results that exceeded the final Primary Drinking Water Standards (PDWS), the SRS flagging criteria, or the SRS turbidity standard are the focus of this report. During second quarter 1995,more » tritium exceeded the final PDWS in all four HAC wells, with activities from 2.3E + 01 to 4.47E + 01 pCi/mL. Aluminum exceeded its Flag 2 criterion in all four HAC wells, ranging from 77.1 to 178 {micro}g/L. Iron exceeded its Flag 2 criterion in wells HAC 1, 2, and 3; the maximum value was 1,680 {micro}g/L in well HAC 2. Groundwater flow direction in the water table beneath the H-Area Acid/Caustic Basin was to the northwest during second quarter 1995, consistent with historical trends. Throughout the last two years, the groundwater flow direction has been consistently to the northwest or the north-northwest.« less

  • During first quarter 1992, samples from the four HAC monitoring wells at the H-Area Acid/Caustic Basin of Savannah River Plant were analyzed for herbicides, indicator parameters, major ions, pesticides, radionuclides, turbidity, volatile organic compounds, and other constituents. Monitoring results that exceeded the US Environmental Protection Agency Primary Drinking Water Standards (PDWS) and the Savannah River Site (SRS) flagging criteria and turbidity standards during the quarter are the focus of this report. Tritium exceeded the PDWS in HAC 1, 2, 3, and 4 during first quarter 1992. Tritium activities in upgradient well HAC 4 appeared similar to tritium levels in wellmore » HAC 1, 2, and 3. Specific conductance and manganese exceeded Flag 2 criteria in wells HAC 2 and 3, respectively. No well samples exceeded the SRS turbidity standard.« less
