Abstract:
Abstract: The promulgation of Chapter NR 140, Wisconsin Administrative Code, Groundwater Quality, established groundwater quality standards for substances detected in, or having a reasonable probability of entering, the groundwater resources of the state. In addition changes to Chapter 200, Wisconsin Administrative Code, require that large scale subsurface systems with design flows greater than 8,000 gallons per day (gpd) must apply for and obtain WPDES permits from the Wisconsin Department of Natural Resources (DNR) in order to lawfully discharge pollutants to the waters of the state.
Very little is known about the long term operation and treatment capabilities of these systems and the impact of these discharges on groundwater. In order to evaluate the performance of these systems the Department has been monitoring two large scale subsurface soil absorption systems. The two facilities being studied are located at the Village of Wyeville, which has a mound system, and the Town of Scott Sanitary District Number 1, which has an absorption bed system.
