Hydro-Environmental Associates, Inc. (HEA) conducted a soil and groundwater site assessment and site remediation of the former Stone Buick automotive sales and service facility, located within downtown Clearwater, Florida.  HEA initially conducted a Phase I and II Environmental Site Assessment (ESA) which identified the existence of numerous in-ground hydraulic lifts, an oil-water separator, a grease trap, and a septic system.  The Phase II ESA included soil and groundwater sampling at each of the hydraulic lift areas, as well as within the oil-water separator, grease trap, and septic tank and leachfield.

The results of groundwater sampling did not detect waste oil group parameters at any of the sample locations above the applicable groundwater cleanup target levels (GCTL)s.  However soil contamination was detected in the vicinity of several of the hydraulic lift areas, oil-water separator, and grease trap.

HEA oversaw site remediation activities to remove the 11 in-ground hydraulic lifts, associated hydraulic oil and reservoirs; the oil-water separator; grease trap; septic system; and sand filter bed.  Soil screening was conducted by HEA during the site remediation to define and delineate the extent of excessively contaminated soil.  Approximately 35 cubic yards of excessively contaminated soil was removed, transported, and thermally incinerated.

Confirmatory soil and groundwater samples were collected at strategic locations upon completion of the site remediation.  The results of the confirmatory sampling indicated that the contaminated soil had been successfully remediated, and the results of groundwater sampling indicated that concentrations of waste oil parameters were within the applicable GCTLs.
