The site was a convenience store which formerly dispensed gasoline and diesel fuel in Plant City, Hillsborough County, Florida.  ASC performed a Contamination Assessment and submitted a Contamination Assessment Report.  The Contamination Assessment indicated that petroleum fuel impacted ground water had migrated off-site, under a road, and onto an adjoining property.  ASC completed Remedial Activities consisting of Episodic Soil Vapor Extraction/Air Sparging (SVE/AS) and the petroleum fuel constituents were reduced in concentration by several orders of magnitude to monitoring only concentrations.  The clients were a private individual and the Florida Department of Environmental Protection (Petroleum Pre-Approval Program).

This site was a combination golf course/high rise condominium project in Fort Myers Beach, Lee County, Florida.  In order to be in compliance with a South Florida Water Management District (SFWMD) permit, monitoring of surface water discharges into Estero Bay (an Outstanding Florida Water Body) had to be performed during the rainy season (June, July, August, and September) annually.  Surface water samples were collected at the two discharge locations and at two background locations.  Surface water measurements of turbidity, salinity, dissolved oxygen, temperature, pH, and conductivity were collected in the field.  Surface water samples were also collected for laboratory analysis.  The client was a property management firm.

A Phase I/II Environmental Site Assessment was performed.  Former diesel fuel above ground storage tank (AST) locations, farm fields where herbicids/perticides were applied, a research facility, and several burn pit areas impacted soil and/or ground water.  ASC performed further soil screening with an organic vapor analyzer, and collection and laboratory analysis of soil and ground water sample.  The results indicated that diesel fuel impacted soil from six former diesel fuel AST locations had to be excavated and stockpiled on-site.  Arsenic impacted soil also had to be excavated.  Appx. 178 tons of diesel fuel impacted soil was transported off-site for thermal incineration.  Appx. 430 tons of arsenic impacted soil was transported off-site for disposal. The client was a major southwest Florida property developer.

ASC was requested to perform Phase I Environmental Site Assessments (ESAs) on 75 separate properties in 60 days.  The sites were located in southwestern Collier County, Florida.  Many of the sites were inaccessible to a vehicle and the site reconnaissance had to be performed from an airplane.  ASC submitted a separate Phase I ESA report for each site in less than the requested 60 days and the property transactions were completed.  The client was a major property developer in southwest Florida.

ASC performed a Phase I Environmental Site Assessment (ESA).  The Southwest Florida Water Management District and Polk County were performing due diligence prior to property acquisition.  The Phase I ESA identified petroleum fuel impacted soil. ASC also identified a cattle corral as having he potential for pesticide impacted soil.  Phase II ESA activities identified three areas requiring the excavation of petroleum fuel impacted soil.  ASC also delineated an area of toxaphene (pesticide) impacted soil.  Appx. 100 tons of petroleum fuel impacted soil was excavated and transported off-site for thermal incineration.  Appx. 650 tons of toxaphene impacted soil were excavated from the area of the corral and transported off-site for disposal at a non-hazardous waste landfill.  The clients were a private company and the Southwest Florida Water Management District.

ASC was contacted by BORCO to arrange for the transportation and disposal of transformers containing PCB mineral oil and 75 drums of PCB containing mineral oil located at their refinery in Freeport, Grand Bahama Island.  Governing regulations indicated that the PCB mineral oil (hazardous waste) could not be brought into the U.S. and disposed.  ASC located a state-of-the-art facility in France for destruction of the drums and transformers, and treatment and disposal of the PCB containing mineral oil.  ASC arranged and supervised the loading of two shipping containers at the BORCO facility, and shipped the containers to Miami, Florida, for rail transport to Charleston, South Carolina.  The containers were then shipped to Great Britain and on to France.  The containers were then trucked to the applicable disposal facilities.

ASC has performed Contamination Screening Evaluations according the Florida Department of Transportation regulations for four roads in Florida.  The roads included Spirit Lake Road in Winter Haven, Berkeley Road in Auburndale, U.S. Highway 41 extension in Fort Myers, and Ortiz Avenue in Fort Myers.  The purpose of the Contamination Screening Evaluations was to identify potential sources of contamination prior to roadway construction activities.  The roadway corridors were from 1-mi. to 2-mi. in length.  Potential sources of contamination identified included gasoline dispensing facilities, former gasoline stations, dry cleaners, and landfills.

ASC performed a Phase I Environmental Site Assessment (ESA) for an approximate 500 acre wooded tract in Fort Myers, Lee County, Florida.  One recognized environmental condition was identified.  A cattle dip vat was observed in the northwest portion of the subject property.  ASC performed a Phase II ESA and identified arsenic impacted soil and ground water at and near the cattle dip vat.  ASC excavated approximately 100-tons of arsenic impacted soil to below the water table and removed the cattle dip vat for disposal at a non-hazardous waste landfill.  Resultant concentrations of arsenic in soil and ground water were below the applicable regulatory action levels.

An attorney representing the owner of an appx. 7,500 acre cattle ranch, initially contacted ASC to perform a Phase I Environmental Site Assessment (ESA) and Baseline Natural Resources Inventory for the property. The work had to be performed in accordance with the guidelines set forth by the Southwest Florida Water Management District for use of the property as a conservation easement. ASC also provided hydrogeologic consulting services in regard to a parcel of the property to be constructed into an approximate 750 acre settling pond.  The proposed settling pond was to accept dredged slurry material from Lake Panasoffkee.  ASC was able to get the water management district to provide assurances that any outflow water would not negatively impact the property, that they would widen the water courses accepting the outflow water, and replace drainage culverts.
