Book Description

Information regarding potential or actual impacts of 20 sites on area groundwater and surface water was obtained. Analyses included the screening parameters TOX, TOC, oil & grease, phenols, cyanide, and selected Priority Pollutant organics and metals at certain sites. Although the screening parameters of TOX, TOC, and O & G did not provide compound-specific information, they were useful in categorizing sites which had been suspect spill or disposal sites for fuels or solvents. Where compound-specific data were collected, no priority pollutant volatile organic compounds which exceeded a State or Federal Maximum Contaminant Level (MCL) were found in the newly installed monitoring wells or surface water sampling locations. A base production well has shown contamination in excess of the proposed MCL for trichloroethylene. In addition, phenols and selected metals were found to exceed MCLs at localized groundwater or surface water sampling locations. Overall base water quality was concluded to be generally good with respect to State and Federal Standards. Two sites were recommended for 'expedited remedial actions' involving former storage tanks and buried drum removal.
