Environmental Site Assessments

Phase I Environmental Site Assessments (PIESA)

MMG professional staff are able to perform Phase I Environmental Site Assessments (PIESA) to review current environmental data relevant to a Site and to summarize reports concerning potential or known Recognized Environmental Conditions (RECs), as per the ASTM E 1527-13 standard, at the Property and/or at adjacent sites to the Site. During the course of the PIESA investigation, MMG personnel review current site conditions and records of historical site usage for evidence of any activity that might have an adverse environmental impact on the Site. This assessment is conducted in a good commercial and customary fashion at the Property with respect to the range of hazardous substances, pollutants, or contaminants within the scope of the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), including petroleum product contaminants. The PIESA has been completed to determine the potential for contamination by means of appropriate inquiries into previous ownership and into uses of the Site consistent with good commercial or customary practices. 

Phase II Environmental Site Assessments (PIIESA)

MMG can also perform PIIESAs to determine whether soil/groundwater contamination is present at the Site, in association with historic site usage, at the Site itself or adjacent properties. Soil samples are collected throughout the Site from boreholes at the Site and are analyzed for various parameters including VOCs, SVOCs, TPH-ORO,-GRO & -DRO, pesticides, herbicides, and RECAP metals. Groundwater sampling is performed with piezometer wells which are typically collocated with the soil sampling boreholes for the purpose of groundwater sampling. Groundwater sample analysis includes herbicides, pesticides, PCBs, VOCs, SVOCs, TPH-ORO,-GRO & -DRO, and RECAP metals.

RECAP/VRAP Investigations

The LDEQ Risk Evaluation/Corrective Action Program (RECAP) and Voluntary Remedial Action Plans (VRAP) are based on soil/water contamination investigations of a site for addressing present and past uncontrolled constituent releases. The plans are prepared in accordance with the LDEQ VRP requirements for voluntary remedial action including the regulations and requirements as stated in Louisiana Administrative Code (LAC), Title 33, Part VI, Chapter 9, Section 911B (LAC 33:VI.Chapter 9, §911B).
