Environmental and Hazardous Materials Investigations for Redevelopment ā€“ Former Industrial Facility ā€“ Columbus, Ohio

STONE conducted a Phase I Environmental Site Assessment (ESA) at this former manufacturer and distributor of gaskets. The Phase I ESA investigation found recognized environmental conditions (RECs) associated with past and current uses of the site and surrounding properties. Historical findings in addition to the rubber manufacturing on the property included plating operations, painting, oil-fired boiler, and oil-filled transformers. In addition, existing groundwater monitoring wells were present on the site. Phase II ESA investigations were conducted to further investigate these conditions. This included soil and groundwater sampling and analysis, soil vapor intrusion investigations, and sub-slab soil vapor sampling. The findings of these additional investigations were evaluated and recommendations were made to enable the property to be redeveloped for commercial use.

STONE also conducted a Comprehensive Asbestos Survey and Regulated Hazardous Materials Assessment. This survey included the collection of over 200 samples for asbestos analysis and an inventory of other hazardous materials in this 60,000 square-foot building. The project was completed according to strict time and budget constraints.

I just wanted to reach out to both of you & all of Stone for your outstanding effort, due diligence & professionalism on this project.

Iā€™m certainly no ESA expert, but I was blown away by the detail contained in your report, especially given the tight timeframe that was required for delivery.

Please know that your work at Walnut Grove is very much appreciated by everyone here at POAH.

For the record, I am now a huge fan of Stone Environmental, and I hope we will continue our working relationship well into the future.
