April Compliance Tip

The LSPA presented the following compliance tip at the April Membership Meeting at the Holiday Inn in Taunton, MA on April 23, 2019.  


When assessing the extent of release as required for Risk Characterizations, if OHM concentrations (excluding VOCs) in GW are greater than GW-3 within 500 feet of a surface water body, or if OHM are detected in GW within 200 feet of a surface water body, these OHM should be analyzed for in the surface water and/or sediment.  
MCP 310 CMR 40.0904(2)(c)(1 and 2)

The need for such measurements may be obviated by technical justification consistent with 310 CMR 40.0193.
