Note: Maine DEP uses a decision tree approach to establish remediation standards. Four categories of sites are Baseline 1 (BL-1), Baseline 2 (BL-2), Intermediate (IN), and Stringent (ST), depending upon geologic vulnerability of site and availability of public water.
* Remediation of groundwater is required at ST sites only. The State of Maine plans to reassess its Maximum Exposure Guidelines (MEGs) on which the cleanup levels for Total Gasoline and Total Fuel Oil are based.
