When solvents and other chemicals were found in a municipal well in Pawling, N.Y., nearby manufacturers were asked to investigate their properties to help determine the source. Low levels of similar chemicals were found in production cooling water wells at Pawling Corp., a plastics and rubber manufacturer. The Pawling property is upgradient from the municipal well site and separated from it by wetlands and a narrow stream, the Swamp River. The area's hydrogeology is complex, and no connection has been established between contamination at the two locations. However, Pawling identified the contamination's source on its property and treated the problem aggressively with air sparging. The hazardous waste source at the site was identified as an area on which solvents historically had been disposed by burning in open trenches. A soil-gas survey, soil borings, field gas chromatography of soils, and confirmatory laboratory analysis of soil and groundwater samples were used to define the vertical and lateral extent of affected soil and groundwater. An estimated 3,000 pounds of volatile solvents were present in subsurface soils and groundwater.
