bull Groundwater is contaminated with volatile organic compounds (VOCs) - chemicals that evaporate in air easily such as solvents
bull The VOCs most prevalent in the groundwater includebull Tetrachloroethene (PCE)bull Trichloroethylene (TCE)bull 12-dichloropropane (12-DCP)
bull PCE and TCE are used as metal degreasers in manufacturing while 12-DCP is a pesticide commonly used many years ago

bull Investigations have shown that contamination has flowed under Vernayrsquos eastern property boundary
bull Groundwater is contaminated with volatile organic compounds (VOCs) - chemicals that evaporate in air easily such as solvents
bull The VOCs most prevalent in the groundwater includebull Tetrachloroethene (PCE)bull Trichloroethylene (TCE)bull 12-dichloropropane (12-DCP)
bull PCE and TCE are used as metal degreasers in manufacturing while 12-DCP is a pesticide commonly used many years ago
