Metallurgical Laboratory Hazardous Waste Management Facility groundwater monitoring report. Second quarter 1995

PDF Version Also Available for Download.

Description

During second quarter 1995, samples from seven new AMB groundwater monitoring wells at the Metallurgical Laboratory Hazardous Waste Management Facility (Met Lab HWMF) were analyzed for a comprehensive list of constituents. Two parameters exceeded standards during the quarter. Lead and nickel appear to exceed final Primary Drinking Water Standards (PDWS) in AMB-18A. These data were suspect and a rerun of the samples showed levels below flagging criteria. This data will be monitored in 3Q95. Aluminum, iron, manganese, boron, silver and total organic halogens exceeded Flag 2 criteria in at least one well each during second quarter 1995. This data, as ... continued below

Description

During second quarter 1995, samples from seven new AMB groundwater monitoring wells at the Metallurgical Laboratory Hazardous Waste Management Facility (Met Lab HWMF) were analyzed for a comprehensive list of constituents. Two parameters exceeded standards during the quarter. Lead and nickel appear to exceed final Primary Drinking Water Standards (PDWS) in AMB-18A. These data were suspect and a rerun of the samples showed levels below flagging criteria. This data will be monitored in 3Q95. Aluminum, iron, manganese, boron, silver and total organic halogens exceeded Flag 2 criteria in at least one well each during second quarter 1995. This data, as well, will be confirmed by 3Q95 testing. Groundwater flow directions in the M-Area Aquifer Zone were similar to previous quarters; the flow rate estimate, however, differs because of an error noted in the scales of measurements used for previous estimates. The estimate was 470 ft/year during second quarter 1995. Reliable estimates of flow directions and rates in the Upper Lost Lake Aquifer Zone could not be determined in previous quarters because data were insufficient. The first estimate from second quarter 1995 shows a 530 ft/year rate. Reliable estimates of flow directions and rates in the Lower Lost Lake Aquifer Zone and in the Middle Sand Aquifer Zone of the CBCU could not be calculated because of the low horizontal gradient and the near-linear distribution of the monitoring wells. During second quarter 1994, SRS received South Carolina Department of Health and Environmental Control approval for constructing five point-of-compliance wells and two plume definition wells near the Met Lab HWMF. This project began in July 1994 and was completed in March of this year. Analytical data from these wells are presented in this report for the first time.
