310 CMR, § 40.0972 - General Approach to Method 1

A Method 1 Risk Characterization compares the conditions at the disposal site to promulgated MCP Method 1 Standards. Each list of groundwater and soil standards has been developed by the Department considering a defined set of exposures considered to be a conservative estimate of the potential exposures at most sites. The exposures assumed by the Department correspond to the groundwater and soil categories described in 310 CMR 40.0932 and 310 CMR 40.0933. The Exposure Points and Exposure Point Concentrations shall be identified in a manner consistent with those categories, such that the concentrations of oil and/or hazardous material detected in soil and groundwater shall be compared directly to the MCP Method 1 Standards.
