Environmental Site Assessment

Environmental Site Assessment

GORE™ Surveys for Environmental identify, quantify and delineate volatile and semi-volatile organic compounds (VOCs, SVOCs) in soil gas, water, air and sediment. Passive sampling using the patented GORE™ Module (GORE-SORBER®) is flexible, easy, cost effective and provides reliable results for:

  • Site assessments
  • Ground water sampling
  • Vapor intrusion studies
  • Sediment sampling

ASTM and US EPA method protocols are employed, and the US EPA has verified the performance claims of the GORE™ Module for soil gas and groundwater sampling.



Site assessment – GORE™ Surveys provide a cost-effective, easy-to-use, and accurate method to investigate and assess the source and extent of soil and groundwater contamination.


Vapor Intrusion – GORE™ Surveys provide a wealth of useful information regarding volatile and semi-volatile organic compound presence in soil gas, subslab soil gas and air for vapor intrusion investigations.


Groundwater Sampling – The unique membrane properties of the GORE™ Module allow for simple and accurate sampling of groundwater contaminant concentrations.


Sediment Sampling – The unique membrane properties of the GORE™ Module allow for contaminant characterization of sediments and sediment porewater in rivers, estuaries and embayments.

GORE™ Surveys provide a simple, accurate, versatile, economical, comprehensive, and proven sampling approach which will focus subsequent sampling, reduce costs, optimize conceptual site models and remedial programs, and accelerate site closure. The survey is used in all 50 states and in many countries worldwide. The survey is used in Triad investigations reducing the more intrusive and expensive sampling with on-site tools. The survey is routinely written into RF/RI workplans at state and Federal levels. The unique material properties of the GORE™ Module (GORE-SORBER®)combine to create a universal sampler that can be deployed in virtually any site setting.
