The objectives were to sample priority landfills with known biohazards and to compare contaminant concentrations in the solid waste extracts with the concentrations found in the ground water, surface runoff, or sump leachate collected at the various landfills. In this report, the water samples obtained are collectively referred to as landfill leachates. Six landfill sites receiving a variety of industrial and municipal solid wastes were sampled. The extracts and landfill leachates for each site were analyzed for the elements and compounds listed in the National Interim Primary Drinking Water Regulations (NIPDWR) (As, Ba, Cd, Cr, Pb, Hg, Se, Ag, four pesticides (Endrin, Lindane, Methoxychlor, and Toxaphene), and two herbicides (2,4-D and 2,4,5-TP)), which are used to define toxic solid wastes. Either the extract or landfill leachate from five of the six landfills were found to contain at least one toxic element in excess of the NIPDWR concentrations. The only elements found in concentrations exceeding the NIPDWR were As, Ba, and Cr. None of the samples contained the pesticides or herbicides listed in the NIPDWR. Only one site was found to contain an element in excess of the regulation concentrations for both the extract and leachate. Three of the sites showed higher concentrations in the landfill leachate.
