Project Summary

Blackstone completed a limited Phase II Environmental Site Assessment for the City of Kansas City, Missouri at the Former Acme Cleansing Facility located at 3200 Gillham Road, Kansas City, Jackson County, Missouri. The Phase II ESA was performed to determine the presence of environmental impacts related to historical dry-cleaning activities at the Site and potential impacts related to former auto service stations and dry cleaners located nearby. Four naphtha tanks and a fuel oil tank were identified in the alley to the west of the Site on the 1951 and 1963 Sanborn maps and the operation of a carpet cleaning business with a naphtha washroom is noted.  No documentation was available indicating that the naphtha tanks had been removed.

Prior to Phase II ESA field activities, Blackstone performed a ground penetrating radar (GPR) survey to determine the existence of buried tanks. The GPR survey identified three areas as the locations of probable USTs in the alley to the west of the building which generally corresponded to the locations of USTs identified on the 1951 and 1963 Sanborn Maps as naphtha tanks.

As part of the field investigation, five soil borings and four temporary piezometers were installed. Petroleum hydrocarbon impacts, including VOCs and gasoline and diesel range organics, were identified in soil and groundwater samples collected during the Phase II ESA. These impacts may be indicative of a naphtha release and are likely related to historical dry-cleaning activities at the Site. Due to the presence of multiple buried utilities in the alley west of the Site, two soil boring locations and one soil boring/temporary piezometer could not be installed during the Phase II ESA field activities. Without data results from the three boring locations in the alley, the source(s) of hydrocarbon and VOC impacts could not be conclusively identified. To address this data gap, Blackstone recommended the use of air knife technology to aid in the location of utilities and allow for the safe collection of the additional samples and to determine the presence of possible buried tanks at the Site.
