Dry Cleaning Facility in Central Vermont

Lincoln Applied Geology, Inc. (LAG) helped a busy dry cleaning business efficiently remediate a contaminant plume associated with dry cleaning chemical byproducts. As part of the remediation design, LAG defined the extent of the large perclorethylene (PCE) contaminant plume through the installation of monitoring wells, soils sampling and air sampling. LAG designed and field tested an in-situ chemical oxidation plan tailored to the fine-textured soils of the site. After the injection, pilot-test, soil-contaminant concentrations were reduced 10 fold.

Gasoline Station, Eastern Massachusetts

After the removal of a failing underground gasoline storage tank, extensive contamination was discovered in the soil and groundwater. This contamination threatened to leach into a nearby stream. LAG designed and implemented a successful, multi-phased remediation plan that reduced on-site contamination in compliance with Massachusetts's stringent standards. This remediation plan included:

  • Multi-Phase Extraction (MPE) which extracts liquid and vapor phase contaminants
  • Soil Vapor Extraction (SVE) which volatizes compounds
  • Air sparging
  • Bio-venting
  • Intrinsic bioremediation/natural attenuation
  • Enhanced bioremediation/natural attenuation utilizing Oxygen Release Compound (ORC ®)

Pay-for-Performance Remediation of an Eastern Vermont Automobile Repair Garage

An extensive contamination plume was discovered beneath an automobile repair facility in eastern Vermont. LAG is fulfilling a "Pay-for-Performance" remediation plan. "Pay-for-Performance" establishes clean-up milestones that must be met prior to receiving payment.

Remediation of a Gasoline Facility in Eastern Massachusetts

LAG identified extensive gasoline-related contamination during the excavation of six underground storage tanks at a gasoline station in eastern Massachusetts. LAG installed a groundwater interceptor trench to prevent further discharge of the contaminants into a nearby wetland. This wetland was part of a network of recharge zones for the regional aquifer reservoir. In addition to the trench, LAG installed four OCR® injection wells. LAG successfully terminated the leaching of contaminants into the nearby wetland.
