The northeastern edge of the site is about 1/2 mile from the American River. Since 1953, Aerojet and its subsidiaries have manufactured liquid and solid propellant rocket engines for military and commercial applications and have formulated a number of chemicals, including rocket propellant agents, agricultural, pharmaceutical, and other industrial chemicals. In addition, the Cordova Chemical Company operated chemical manufacturing facilities on the Aerojet complex from 1974 to 1979. Both companies disposed of unknown quantities of hazardous waste chemicals, including trichloroethylene (TCE) and other chemicals associated with rocket propellants, as well as various chemical processing wastes. Some wastes were disposed of in surface impoundments, landfills, deep injection wells, leachate fields, and some were disposed of by open burning. Underlying the site are extensive 40 to 100 foot-deep dredge tailings, a remnant of past gold mining operations.<br><br>In 1979, volatile organic compounds (VOCs) were found off-site in private wells and in the American River in 1983. Perchlorate, a component of solid rocket fuel, was found in drinking water wells off-site above the provisional reference dose range in January 1997. The communities potentially affected by this site are Rancho Cordova, population 55,000; Carmichael, population 49,000 and Sacramento, population 407,000. The closest residence is about 500 feet away from the site. Groundwater is used extensively throughout the Rancho Cordova area to supply municipal, domestic, industrial and some irrigation water. Public and private drinking water supply wells have been contaminated and wells contaminated above action levels have been closed. Aerojet continues to monitor drinking water supplies to assure compliance with drinking water standards. Lake Natoma and Alder Creek are nearby and are used for recreational activities. The American River is used for public water supplies.<br>*******************<br><br>I lived near the American River at this time and remember Aerojet. They made the original space shuttle engine at this facility(if I remember right).When it was first relized that TCE was leaking into the river Aerojet downplayed it talking about 'acceptable levels'.<br><br>It appears this sort of thing has always happened and pretty much continues to happen. So its no surprise the Pentagon has no desire to help out the environment, afterall that would mean more costs for their corporate buddies.<br><br><br><br> <p></p><i></i>
