The purpose of this report is to provide guidance to stormwater planners, drainage engineers, and local regulatory personnel concerning groundwater contamination potential of stormwater infiltration practices. It includes and extensive literature review of groundwater problems associated with stormwater. Most stormwater can likely be infiltrated with minimal impacts. Removal processes in soils are likely to reduce most infiltrated pollutants. However, some pollutants are much more likely to cause problems than most. These must be more carefully considered in infiltration projects. Critical pollutant source areas need to be avoided and pretreatment before infiltration to remove particulate forms of the pollutants should be considered.
