State regulators awarded Lakeshore Environmental the contract to clean up groundwater contamination at a former dry cleaning facility. Dry cleaning solvents at this EPA Superfund site were threatening the quality of local drinking water supplies and the ecological stability of a “blue ribbon” trout stream and national wild and scenic river. Lakeshore’s responsibilities included the following tasks:
- Monitoring well installations
- Collection of soil samples
- Produced geologic cross-sections illustrating soil lithology and groundwater flow
- Determined the horizontal and vertical extents of contamination
- Upgraded previously installed recovery equipment
- Continuously monitored contamination levels, adjusted recovery equipment to maximize effectiveness of remediation efforts
- Worked in unison with the state regulators to monitor the extent of contamination
- Measured groundwater drawdown to define the product capture zone and analyze treatment effectiveness
The project has resulted in the successful capture of the plume and contamination has not reached the river.
