The purpose of this investigation is to determine compliance with applicable laws and regulation. Four waste disposal sites are being investigated by EPA: Love Canal, Hyde Park Landfill, S-Area Landfill, and 102nd Street Landfill. Extensive sampling of groundwater, and/or surface waters and sediments have been conducted at these sites by EPA Region II and State agencies. To supplement these data, the National Enforcement INvestigations Center (NEIC) was requested to collect additional groundwater and surface water samples from and adjacent to the Hyde Park, S-Area and 102nd Street Landfill sites for mutagenicity and chemical analyses. Sampling was conducted on July 12, 1979. In addition to the analyses for mutagenic substances, analyses were performed for organic priority pollutants. Air sampling was conducted at the Hyde Park Landfill site to determine if airborne pollutants from Hooker operations were present. The potential source of these pollutants is emission of volatile materials from the holding ponds into which the leachate collected from the landfill is pumped. These ponds are presently covered with a 22 mil plastic sheet to prevent emissions. All samples collected were shipped to the NEIC laboratories Denver, Colorado, for analyses. Document control, Chain-of-Custody, and quality control/quality assurance procedures of the NEIC were followed during this study. |
