Repeatable multilevel groundwater sampling (RMGS) is a tool for tracking contaminant concentration trends over time at fixed locations but at depth-discrete intervals within an aquifer. The data from RMGS methods can be integrated with other sampling results to improve the conceptual site model and the understanding of contaminant distribution in both a vertical and horizontal sense. engineered systems for RMGS have both advantages and limitations when compared to clusters of conventional wells or nested wells as summarized in this fact sheet. A case study highlights where RMGS wells were used at a former landfill site at Naval Base Kitsap Keyport to provide vertically discrete monitoring of contaminant concentrations over time.
