Harlem, NY, September 2011 – GRANT engineering was hired as an environmental consulting firm to perform a Phase II environmental investigation and prepare a Remedial Investigation Report (RIR). The purpose of this subsurface ground investigation was to assess if the 2,000 SF lot was contaminated.
GRANT’s environmental engineers conducted a site inspection, coordinating a driller subcontractor, to identify AOCs and physical obstructions (i.e. structures, buildings, etc.), installed five soil borings across the entire project site, and collected nine soil samples for chemical analysis from the soil borings to evaluate soil quality. GRANT also installed one groundwater monitoring well and collected three canisters for Soil Vapor Analysis. During site activities, the presence of an MTA-owned subway line near the western portion of the lot was identified.
For efficient permitting and information sharing, GRANT established contact with an MTA engineer in charge of permits at the CMP Engineering Services Department. This relationship has proven useful on previous projects, and can serve as a valuable tool in developing a boring location program where accurate information and careful planning is critical.
After reviewing the LAB results from soil, water and vapor GRANT prepared a RIR reporting findings and recommendations for the client.
