Description:
It has been over 10 years since the low-flow ground water purging and sampling method was initially reported in the literature. The method grew from the recognition that well purging was necessary to collect representative samples, bailers could not achieve well purging, and high-flow purging produced large volumes of potentially contaminated water in need of transport and treatment. Low flow has been widely adopted, leading to documented, consistent performance in diverse hydrogeologic settings for virtually all analytes of interest.
