Projects

Phase I Environmental Site Assessment - Naples, Maine

Test pit investigation of floor-drain effluent using a backhoe to excavate the area. Photoionization detector used to analyze the discharge of the floor drain pipe and assess the need for groundwater cleanup.

Phase I & II Environmental Site Assessment - Lisbon Falls, Maine

Hydrogeological investigation to characterize the extent of petroleum-contaminated soils associated with an old service station. Investigations included the supervision of subsurface explorations and screening soils for petroleum. Further site investigation also included a soil gas survey to characterize the risk of vapor intrusion as a result of residual contamination on-site. We coordinated with the Maine Department of Environmental Protection to clarify the site's environmental liabilities through the Voluntary Response Action Program (VRAP).

Phase II Environmental Site Assessment - Windham, Maine

Hydrogeological investigation to characterize the extent of mercury contamination associated with the routine disposal of mercuric nitrate into a septic system. Services included the stratified sampling of the septic tank, supervision of test boring installation, continuous split-spoon sampling, monitoring well installation, low-flow sampling, analysis of results and communication with the Maine DEP.

Waterville Landfill - Waterville, Maine

Monitoring wells were drilled and tested for permeability, water table elevation, and materials logging. Surficial geologic mapping and contaminant transport for assessment of the landfill.

Burnt Mills Development - Wells, Maine

Investigation and location of groundwater supply for a 175 unit subdivision followed by nitrate and mounding studies.

Oxford Casino - Oxford, Maine

Groundwater contamination remediation for large commercial project, followed by a nitrate study predicting the potential for nearby lake contamination from this proposed large septic system.

Private Property - Kennebunk, Maine

Wetland delineation study, Tier 3 permit approval from the DEP. Project also required and received approval from the Maine Department of Inland Fisheries and wildlife and the Army Corp of Engineers.

Cottages at Salt Marsh - Kennebunk, Maine

Groundwater impact (nitrate) study for a seven lot subdivision on private septic systems.

Private Residence - Sebago Lake, Maine

Complex septic system design for lakefront property. Design incorporated three cottages on small lots utilizing one system with severe shoreland zoning restrictions. The complex septic design required and received town, state and Portland Water District approval.
