- Soil/sediment/groundwater/drinking water investigations and remediations.
- Monitoring well installation and sampling.
- Hydrogeologic assessments, including lineament studies and tracer studies in both fractured bedrock and overburden aquifers.
- Implementation of remedial actions:
- Soil – source removal and in-situ bioremediation;
- Water – pump & treat, LNAPL product removal, in-situ bioremediation.
- GPS surveying and mapping;
- Completion of PADEP Form U applications (including sampling and analysis) to allow for landfill disposal of well drilling/completion waste streams (including coordination with landfills and PADEP);

More than 60 successful site remediations have been completed encompassing releases of diesel from various sources (stationary generators, drilling equipment, tanks, etc.); drilling mud; frac fluid; brine used as part of drilling operations (frac plug perforations, etc.); and produced brine from flowback operations and storage
tanks.
