<br />- 12 - <br /> <br />Intermediate Problems: Well injection; Pesticides; Fertilizers; <br />and septic tanks. <br /> <br />Minor Problems: Salt water/brackish water intrusion; Road salts; <br />and Feedlots. <br /> <br />Varies: Wastewater treatment; Land a~~lication; and Mining. <br /> <br />Some of the most troublesome contaminants from these sources <br />include: <br /> <br />o Gasoline (ethylene dibromide/ethylenedichloride, benzene) <br />o Organic solvents (TCE, TCA, benzene) <br />o Heavy metals (cadmium, lead, chromium, mercury) <br />o Inorganic chemicals (ammonia, cyanide) <br />o Organic chemicals (PCB, PBB) <br />o Pesticides and soil fumigants (DBCP, DBCP, aldicarbl <br />o Pathogens and Nitrates <br /> <br />and a variety of other hazardous and non-hazardous wastes. One <br />estimate indicates that there are now over 61,000 chemicals on <br />the market and several hundred are added each year.1I <br /> <br />Inaoorooriate waste disDosal account~for .a substantial <br />amount of around-water contamination. Many types of waste dis- <br />posal on and into the land pose obvious risks to ground water <br />quality. Despite this, past decisions on locating hazardous <br />waste disposal facilities give evidence of scant consideration <br />of potential adverse - impacts.~- - r.ndiscriminate-- disposal- of- toxic <br />and hazardous chemicals onto the land has given rise to Federal <br />cleanup programs under the Superfund legislation and other State <br />clean-up efforts. While the full number of such facilities <br />remains unknown, EPA and the States identify an inventory of <br />about 16,000 potential sites, of which as many as 5,600 have <br />been screened. Of this number, 539 are now listed for priority <br />attention under Superfund.~/ <br /> <br />In addition to facilities recelvlng hazardous wastes, other <br />facilities that may contaminate ground water are subjects oE <br />national concern. In the mid 1970's, EPA and the States became <br />aware that waste disposal landfills (not just those receiving <br />hazardous wastes under RCRA) were also creating a problem for <br />ground water. There are an estimated 93,000 such landfills in <br />the United States. Of these, 75,000 are classified as on-sitel <br />industrial, and we know little about tn~ Anc&her lB.500 are <br />classified as munici~al.71 Fewer than 10 States require any <br />form of regular monitoring for ground water quality at these <br />facilities. While there are no current data on the impact of <br />
