AEM was retained by a chemical company to investigate a pesticide formulating facility that operated for more than 50 years on a 15-acre industrial property in Forest Park, Georgia. AEM's client sold its business but maintained the property, which was placed on Georgia's Hazardous Site Inventory (HSI). The subject site is located in a highly industrialized area where there are numerous existing and previous industries that used hazardous materials. AEM was retained in 1995 to develop the Compliance Status Report; selection was based upon overall qualifications. AEM has been responsible for the overall development of the CSR. Due to budgetary considerations and off-site access issues, AEM performed the assessment in phases. On- and off-site soil samples, on- and off-site groundwater samples, and off-site sediment samples have been collected and analyzed. Working primarily to coordinate the effort with our client's outside counsel in Atlanta, AEM prepared the CSR for submittal to EPD.

The site is complicated from several standpoints. The facility has extensive soil and groundwater contamination with pesticides and potential pesticide carriers, including various organics. Pesticide contamination has been detected on off-site properties. Also, several properties that were assessed off site and hydraulically downgradient have apparently been contaminated from other HSI sites resulting in co-mingled plumes, making the site assessment and evaluation of potential corrective actions complicated from physical and regulatory standpoints.

AEM performed all aspects of the CSR including the assessment of all media. Monitoring wells were installed in both shallow and deep aquifer zones. AEM was specifically responsible for sections of the Compliance Status Report addressing the findings, source identification, receptor survey, development of Risk Reduction Standards, and the performance of an engineering feasibility study to determine the most feasible and affordable corrective action for the site. Additionally, AEM assisted outside counsel in the development of an innovative facility certification to multiple Risk Reduction Standards.
