Title: P-Area Acid/Caustic Basin groundwater monitoring report: Second quarter 1993

Technical Report ·
DOI:https://doi.org/10.2172/10109459· OSTI ID:10109459

The six monitoring wells at the P-Area Acid/Caustic Basin are sampled quarterly as part of the Savannah River Site (SRS) Groundwater Monitoring Program and to comply with the terms of a consent decree signed May 26, 1988, by the US District Court (District of South Carolina, Aiken Division). During second quarter 1993, samples from the monitoring wells were analyzed for indicator parameters, groundwater quality parameters, parameters characterizing suitability as a drinking water supply, and other constituents. Monitoring results that exceeded the final Primary Drinking Water Standards (PDWS) or the SRS flagging criteria or turbidity standard are discussed in this report. During second quarter 1993, no constituents exceeded the final PDWS in wells at the P-Area Acid/Caustic Basin. Aluminum exceeded the SRS Flag 2 criterion in wells PAC 1, 3, 4, 5, and 6. Iron and manganese each exceeded the Flag 2 criterion in wells PAC 2, 3, 5, and 6. Lead was elevated above its Flag 2 criterion in well PAC 5, and radium-228 was above its proposed DWS (Flag 2) in wells PAC 3 and 6. Radium-228 results that exceeded nonvolatile beta activities were reported in these and other wells.
