One of the major issues in this town is water: do we have enough to keep this a green community, at an affordable cost?
Contamination Threats and Mitigation
Laboratory operations since the 1940s resulted in a wide array of chemical releases, often in effluent discharged from wastewater treatment facilities. Many millions of dollars have been spent to monitor and remediate the environmental contamination caused.
Reactive contaminants, including plutonium and other radionuclides, tend to adhere to solid surfaces, so they usually have not moved very far in groundwater. In fact, wastewater effluent (now treated to strict standards to prevent further contamination) is used to irrigate vegetation holding soil in place to keep previously deposited surface contamination from spreading.
Non-reactive contaminants, including hexavalent chromium, tritium, nitrate and explosives components perchlorate and RDX, have traveled farther in our groundwater, in some cases reaching portions of our aquifer. The presence of these contaminants above naturally occurring levels has not been detected in our water supply wells, but unless carefully monitored and properly remediated, they could threaten our water supply.
