"The DoD, the nation's biggest polluter, is now cleaning up 29,500 currently or formerly contaminated sites in every state and territory. California alone has 3,912 contaminated sites on 441 current and former DoD installations. Many of DoD's facilities have already contaminated groundwater sources of drinking water.... The cost to clean up toxic munitions contamination and unexploded ordnance at active and former military installations around the country may reach $200 billion." - The National Resources Defense Council, April 21, 2004.
