Course Description:

The assessment and remediation of groundwater contamination requires knowing the magnitude and distribution of the hydraulic conductivity of soils and sediments. Slug testing of monitoring wells has become the most common means of determining hydraulic conductivity at contaminated sites. However, slug testing can be problematic when wells are screened across the water table because of backfill zone drainage or in high permeable formations that exhibit rapid recovery and oscillatory response.

In this course you will learn how to determine hydraulic conductivity from the steady state drawdown and discharge achieved while low flow sampling. The method avoids some of the problems associated with slug testing and provides synchronous data with water quality sampling. Furthermore the method is useful in evaluating whether remediation methods are influencing the hydraulic conductivity and whether, over time, fines are clogging well intakes. The course covers single and multiple discharge-drawdown testing, and includes "hands-on" simulations for honing your skills, a video demonstration, spreadsheets for test and sensitivity analyses, and example case histories.
