Site Investigation and Remedial Technologies

CSE harmonizes cost-effective site investigations with client-oriented remediation services. Our site investigation activities establish the nature and magnitude of impacts in the subsurface environment and determine the fate and transport of contaminants. Our geologists and engineers evaluate subsurface conditions and recommend response strategies based on and consistent with planned land use.

Essentially, we determine the client goals, define the environmental problem, and develop a cost-efficient and effective solution. CSE utilizes many approaches to obtain case closure. In some cases, implementing a remediation system or excavation activities reduces existing contaminant concentrations to below applicable regulatory standards and allows for unconditional case closure. In other cases, CSE uses site-specific data to illustrate that case closure is warranted and further project expense is unnecessary. Some of our service include:

Testing and Investigation Operations

  • Soil Boring and Groundwater Monitoring Well Installation
  • Soil, Groundwater, Sediment, Soil Gas, and Indoor Air Sampling
  • Test Pitting
  • Geotechnical Evaluations
  • Soil Gas Probe Installation
  • Vapor Intrusion Assessments

Remediation Technologies

  • Soil Excavation and Disposal/Recycling/Reuse
  • High-Vacuum Extraction
  • Groundwater Extraction (Pump & Treat)
  • Underground Storage Tank (UST) Assessment and Closure
  • Sub-Slab Depressurization System (SSDS)
  • Soil Vapor Extraction (SVE) Systems
  • Bioremediation
  • In-Situ Chemical Oxidation (ISCO) Injections

Limited Site Investigation

A Limited Site Investigation (LSI) consists of a tailored range of activities designed to assist bankers, realtors, developers, and homeowners evaluate properties and vicinity exhibiting questionable environmental risks in a cost effective and timely manner.

LSI Operations include, but are not limited to:
  • Environmental Database Review
  • Regulatory Report Interpretation
  • Site Visit to Evaluate Environmental Risk
  • Shallow Subsurface Borings
  • Limited Sampling (e.g., soil, groundwater, indoor air, etc.) within an Area of Concern (if necessary)
  • Letter Report Containing our Findings & Recommendations

CSE provides on-site assistance coupled with confirmatory sampling in order to evaluate the potential release and reassure the buyer that a property has not been contaminated in order to save the deal.

Examples of scenarios that would require a LSI for a property include:
  • Non Reportable releases of oil and hazardous materials (i.e., evidence of leaks, spills or staining)
  • Old and/or corroded aboveground storage tanks (ASTs)
  • Greenhouses utilizing pesticides
  • Properties within historic industrial mill districts
  • Stained soil or stressed vegetation
  • Garages with floor drains
  • Properties with PCB containing items (e.g., Caulking, Floor finish, Plastics, Adhesives, Thermal insulation material, Old electrical equipment/devices, Oil-based paint, Fluorescent light ballasts, etc.)
  • Properties neighboring a(n); gasoline station, motor repair facility, commercial printing facility, dry cleaners, photo developing laboratory, junkyard or landfill
