Blackstone completed a Phase I Environmental Site Assessment (ESA) and a limited Phase II ESA for a former foundry and iron works located in Topeka, Kansas.
The limited Phase II ESA was requested in response to Recognized Environmental Conditions (RECs) identified as part of Phase I ESAs completed for the Site. Historical information identified for the Site indicated that it was developed with residences by 1883. Subsequent to that time, the Site was home to a coal company, a dye shop and tailor, a steam laundry/dry cleaner, a liquor bottling company, and a foundry and iron works. Recognized Environmental Conditions identified during the Phase I ESA included on-site drycleaning operations, documented off-site solvent releases, an off-site former manufactured gas plant (FMGP), an off-site filling station, auto repair facility, and drycleaning operation adjacent to the one of the properties. Blackstone installed twelve soil borings and 11 temporary groundwater monitoring as part of a Limited Phase II ESA to determine potential environmental impacts related to identified RECs.
Based on the Phase II ESA analytical results, soil and groundwater samples analyzed for the Site exhibited concentrations exceeding respective Kansas Department of Health and Environment (KDHE) Risk-Based Concentrations for Kansas (RSKs) for the Residential and Non-Residential Scenarios. Additionally, several inches of free phase product was identified in one temporary groundwater piezometer. Blackstone recommended additional environmental assessment activities to fully delineate the extent of the groundwater contamination and free phase product. At this time, Blackstone is working with the owner of the Site to determine how best to proceed with additional site characterization activities.
