Client’s Needs Site Challenges

As part of the due diligence process for sale of several former manufacturing sites, Pinchin was contracted by the property owners representative to complete Phase I Environmental Site Assessments (ESAs) at seven facilities. Six of the seven Sites were found to be in good environmental condition. However, the main manufacturing plant had historically used petroleum hydrocarbons (PHCs) as part of the manufacturing process and were found in the soil and groundwater at four locations at this property. Pinchin developed a site-specific remediation strategy that allowed the client to effectively manage on-site contamination and successfully sell the properties.

Our Services and Solutions

Each Phase I ESA involved a review of readily available historical records and readily accessible regulatory records, a Site visit, and Site representative interviews. A Phase II ESA was recommended for two facilities based on results of the Phase I ESAs. The Phase II ESA included the collection of soil and groundwater samples in areas identified as part of the Phase I ESA. Following the completion of Phase II ESA program at the two Sites, additional subsurface investigations were recommended for one of the properties. A Supplemental Phase II ESA program was completed at this property which identified subsurface contamination at four areas that required remediation to meet Site closure requirements. Pinchin completed a Remedial Technology Evaluation which indicated that in situ chemical oxidation (ISCO) would have the greatest potential to meet the Site clean-up and remediation goals in the shortest period of time.

As part of the Site-wide solution, Pinchin conducted bench-scale and field-scale pilot testing to evaluate ISCO efficacy and to gather data for full-scale implementation. Following a contractor bidding process, a contractor was selected, a full scale design was completed and costs for the full-scale system were developed. Pinchin initiated full-scale ISCO work in September 2010 and completed the final round of ISCO injection work in March 2011 despite difficult winter weather conditions for completing ISCO. Results of soil and groundwater monitoring indicated that the Site met the applicable MOE standards.

Outcome

Pinchin completed the full-scale remediation program within a seven month timeframe and delivered the project on-budget. During the last phases of the remediation work on-site, the owner was able to successfully sell the properties.
