Statistical Review Workshop for Evaluating Lagoon Seepage Rates

This workshop was open to the public and was specifically designed for professionals that perform seepage tests on lagoons in Idaho. The workshop reviewed data collection and evaluation methods for lagoon seepage testing, with a focus on statistical approaches to review and validate measured seepage rates for compliance determinations. The workshop was presented jointly by DEQ and Jeff Myers, a nationally and internationally recognized expert in characterization, sampling, statistics, uncertainty management, and data quality.
