Groundwater Assessment – Gasoline Station/Convenience Store

Liberty, SC

The Challenge:

Determine the horizontal and vertical extent of petroleum-impacted groundwater caused by leakage of gasoline from an underground storage tank system. The contaminant plume underlies 10 off-site residential properties and a day care facility.

Groundwater Remediation – Bulk Fuel Terminal

Spartanburg, SC

The Challenge:

Remediate a bulk fuel terminal that has operated since World War II. Groundwater was discovered to be impacted over an area of 5+ acres, including numerous off-site residential properties. The petroleum contamination existed as free-phase floating gasoline (over 2 acres) and as dissolved compounds in saturated soils and fractured bedrock aquifers.

Groundwater Remediation – Medical Products Manufacturing Plant

Greenwood, SC

The Challenge:

Rapidly remove diesel fuel floating atop the groundwater in an area on the plant which is underlain by a dense network of electrical, natural gas, and cooling water utility lines. Prior to EnviroSouth’s involvement, diesel fuel remediation was being performed for 8+ years by another consulting firm using passive recovery pumps with minimal effect.

Groundwater Remediation – Industrial Dry Cleaning Plant

Asheville, NC

The Challenge:

Design and implement a monitoring and remediation plan that will protect residents and streams in the area of a plume of dry cleaning fluid (chlorinated solvent) contamination. Prior to EnviroSouth’s involvement, a previous consultant proposed a large-scale remediation approach that did not address the immediate concerns related to soil vapor intrusion in stores and residences in the area or the migration of solvent-impacted groundwater into nearby streams.

Phase I Environmental Site Assessment (ESA) and Heating Oil Tank Removal

Greenville, South Carolina

The Challenge:

As a result of the findings from conducting a Phase I ESA per the appropriate ASTM Standard (ASTM E1527-21), an underground storage tank (UST) was identified on the subject property. Because of the size and location of the tank, it was estimated to have been a former heating oil tank used for facility heating.

Phase 1 Environmental Site Assessment – National Retailer Expansion

50+ Properties in South Carolina, North Carolina, West Virgina, and Ohio

The Challenge:

Perform numerous Phase I Environmental Site Assessments (ESAs) and subsequent Limited Phase II ESAs for a high-volume retail developer. The services were to be completed on aggressive time schedules and met the scrutiny of the client’s lenders and future property investors.

Phase I Environmental Site Assessments – Convenience Store Chain Real Estate Aquisitions

Multiple Sites in Upstate in South Carolina

The Challenge:

Provided full service environmental assessments for multiple locations in a short timeframe. The services included Phase I Environmental Site Assessment by ASTM Standard 1527-13, Underground Storage Tank system compliance inspections, soil assessments, and groundwater assessments.

Building Evaluation – Medical Renovations

Greensboro and Winston – Salem, NC

The Challenge:

Complete surveys and sampling of building materials in pre-existing shopping center buildings to determine the presence of asbestos containing building materials and lead-based paint. The information was needed for architects to plan the demolition and renovation of the facilities for proposed medical clinics.

Brownfields Redevelopment – Automotive Parts Manufacturing Plant

Easley, South Carolina

The Challenge:

Guide our client through the process of negotiating and fulfilling the terms of a Brownfields Voluntary Cleanup Contract (VCC). The contract was needed to allow the client to safely purchase a manufacturing plant that was previously documented to be impacted by groundwater contaminated with trichloroethene (TCE), a chlorinated solvent.

Brownfields Redevelopment – Precious Metals Recovery Facility

Duncan, South Carolina

The Challenge:

Evaluate soil and groundwater conditions underlying a property that is considered a high risk of soil impact by metals based on historical land use. Groundwater is present within fractured bedrock.

Groundwater, Soil Vapor, and Indoor Air Assessment – Industrial Dry Cleaning Plants

Kingsport and Knoxville, Tennessee and Greenville, SC

The Challenge:

Evaluate the extent of contamination related to the leakage of dry cleaning solvent (tetrachloroethene) in the groundwater and creek on and near the former plant properties. The impacted groundwater occurs in soil and fractured bedrock aquifers. Because of shallow groundwater and the presence of solvents in soils underlying the plant building, soil vapors and indoor air quality also require evaluation. The previous detection of solvents in an adjacent creek required a detailed assessment of surface water impact.
