Mechanical Bladder Pump Approved by US EPA's ETV Program
The U.S. Environmental Protection Agency’s Environmental Technology Verification Program (ETV) recently finalized their performance statements on the Mechanical Bladder Pump developed by Geoprobe Systems®, and has given the company and the MBP high marks. The document stated that the MBP collected representative samples and met low-flow sampling protocol recommended by the EPA and many state agencies.
Contained within the four-page document, the ETV statements included: “... the Geoprobe® Mechanical Bladder Pump ... can be used to collect VOC contaminated water samples from monitoring wells such that results are statistically comparable to reference samples. ”
As relating to low-flow sampling protocol, the ETV document also states: “Furthermore, the pump is compatible with sampling programs that incorporate low-volume purge methodologies. ”
The goal of the ETV Program is to further environmental protection by accelerating the acceptance and use of improved and cost-effective technologies. All evaluations are conducted in accordance with rigorous quality assurance protocols to ensure that data of known and adequate quality are generated and the the results are defensible.
Sandia National Laboratories, one of the verification testing organizations within the ETV Center, collaborated with personnel from the U.S. Geological Survey and Tyndall Air Force Base to conduct the verification study of the MBP for deployment in narrow-bore, direct push wells at contaminated sites with potential groundwater contamination.
