Impact/Purpose:
The objective of this task is to increase the acceptance and use of site characterization and monitoring technologies by providing verified performance data and reports on the performance of environmental monitoring and site characterization technologies.
Description:
The U.S. Environmental Protection Agency (EPA) has created the Environmental Technology Verification Program (ETV) to facilitate the deployment of innovative or improved environmental technologies through performance verification and dissemination of information. The goal of the ETV Program is to further environmental protection by substantially accelerating the acceptance and use of improved and cost-effective technologies. ETV seeks to achieve this goal by providing high-quality, peer-reviewed data on technology performance to those involved in the design, distribution, financing, permitting purchase, and use of environmental technologies.
GORE-SORBER module results are reported in terms of total mass of VOC collected in the module. In this format, the data are not directly comparable to the concentration accompanied by the collection and analysis of a conventional groundwater sample, which enables comparison of the two data formats. The correlation between GORE-SORBOR modules data and conventional groundwater sample data was carried out by deploying GORE-SORBOR modules data and conventional groundwater sample data was carried out by deploying GORE-SORBER modules data and reference pump in five different wells with known TCE contamination. Trichloroethene concentration in these 5 wells ranged from 5 to 2,000 ug/L. The observed correlation between GORE-SORBOR module data and reference sample data was very good. The correlation coefficients for the STND and HWEP modules were 0.997 and 0.998 respectively.
