In cooperation with DelDOT, DGS is investigating the physical and chemical impacts of de-icing practices (salting and brining) and stormwater infiltration best management practices (BMP) on groundwater. The goal is to advise DelDOT on potential risks to groundwater quality from de-icing and inform changes to de-icing materials and practices. This project arose because of increasing chloride concentrations observed in a number of groundwater-supplied water systems in New Castle County. Increased concentrations of radionuclides and radiation are observed in some of the impacted water sources.
