Louise Parker has been a Research Physical Scientist at the U.S. Army Engineer Research and Development Center 's Cold Regions Research and Engineering Laboratory (ERDC-CRREL) in Hanover, NH for over 25 years. She has a broad background in environmental chemistry and microbiology. Since the early 1990s, her primary research focus has been ground water monitoring and sampling, and analyte/material interactions, with over 60 publications, presentations, and workshops. Recent research studies have examined the suitability of direct-push (DP) monitoring wells for long-term monitoring and passive ground water sampling methods. Older studies examined sorption of organic contaminants and leaching of constituents by sampling and well casing materials, decontamination of sampling devices, and the affects of harsh environments on sampling and well casing materials. Since 2002, she has been a member of the ITRC Sampling, Characterization, and Monitoring Team, where she has worked on a technical regulatory document on the use DP wells. Since 2003, she has also a member of the ITRC Passive Sampler team, where she has worked on an overview document on passive ground water sampling techniques and a technical regulatory document on five passive ground water sampling methods. Louise earned a bachelor's degree in microbiology from the University of New Hampshire in Durham, NH in 1972 and a master's degree in food science from the University of Massachusetts in Amherst, MA in 1979.
