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.
The Multiprobe 100 consists of two units with tubing and wiring interconnections. A upper receiving module which is deployed at the wellhead on top of the well is 18 inches long. 3.25 inches in diameter, and weighs 3 pounds. The lower sampling module, which is inserted into the water column inside the well, is 12 inches long, 3.25 inches in diameter and also weighs 3 pounds. The system is constructed of Teflon, borosilicate glass, stainless steel and Delrin, a solvent-resistant, acetal homopolymer resin. Electrical solenoid valves are used to select the sampling lever and control gas flow to the sampler. Water level sensors in the water chambers of both modules are used to trigger valve changes during the sampling process. A small, battery-operated microprocessor controller is used to control the valves used during the sampling process.
