used for waste disposal as recently as 1980. Specific information documenting disposal practices is not available. Reportedly, only nonhazardous materials such as spoiled meat, spoiled candy, and clothing have been disposed at the site. Site 10 is located south of First Street in the southernmost part of the old DuPont munitions plant. An estimated 75 to 100 gallons of decontamination agent (DS-2) was reportedly buried at the site. DS-2, which is toxic to humans and corrosive to metals, is used for decontaminating equipment contaminated with nerve or blister agents. DS-2 is 70% diethylene triamine; 28% ethylene glycol monomethyl ether; and 2% sodium hydroxide. It is not known if the DS-2 was neutralized prior to disposal. A magnetometer survey of Site 10 was performed in December 1985. The map shows the anomalous areas in terms of equivalent pounds of iron. While the source of the anomalies may indeed be buried metal, brick, slag, ash, or other disturbances the buried drums could also be the source of the anomalies. The mounds of soil present in the wooded area appeared to contain little iron. Site 12 was a scrap metal disposal site near water tower located approximately 2000 feet west of Jones Pond. The site was used for surface disposal of scrap metal; primarily old automobile parts and iron pipe. Based on visual inspection of the site approximately 10 to 110 cubic feet of material was disposed at the site. Active sites The following are considered sites requiring active environmental actions. Site 4 In the late 1960s, out-of-date, unused, medical supplies, including syringes and empty intravenous bottles, and one-inch metal banding, were unloaded down a bank in this area and covered with soil. Site 4 is a ravine located at the headwaters of an upstream pond and between buildings CAD 11 and CAD 12. It was reported that as much as 7,000 cubic yards of material was disposed at this site. Previously (date unknown), a considerable volume of these materials were reportedly removed from the site because syringe needles were getting stuck in deer hooves. After heavy rains, what appeared to be syringes could sometimes be seen floating in the adjacent pond and in Youth Pond (both upstream and downstream of D Street.) Observations in IAS field notes show that it is possible dyes were disposed of at the site. The location, volume or types of dyes are not known. Site 7: During
