H-Area Seepage Basins groundwater monitoring report. Volume 1, First and second quarters 1993
During the first half of 1993, the groundwater at the H-Area Seepage Basins (HASB) was monitored in compliance with the September 30, 1992, modification of South Carolina Hazardous Waste Permit. Samples were collected from 130 wells that monitor the three separate hydrostratigraphic units that make up the uppermost aquifer beneath the HASB. A detailed description of the uppermost aquifer is included in the Resource Conservation and Recovery Act Part B Post-Closure Care Permit Application for the H-Area Hazardous Waste Management Facility submitted to the South Carolina Department of Health and Environmental Control (SCDHEC) in December 1990. HASB`s Groundwater Protection Standard is the standard for comparison. Historically, as well as currently, gross alpha, nitrate, nonvolatile beta, and tritium have been among the primary constituents to exceed standards. Other radionuclides and hazardous constituents also exceeded the GWPS in the groundwater at the HASB, notably aluminum, iodine-129, mercury, nickel-63, strontium-89, strontium-90, technetium-99, and zinc during the first half of 1993. Elevated constituents are found primarily in Aquifer Zone IIB{sub 2} (Water Table) and in the upper portion of Aquifer Zone IIB{sub 1}. However, constituents exceeding standards also occur in several wells screened in the lower portion of Aquifer Zone IIB{sub 1} and Aquifer Unit IIA.
