BMP design considerations for ground water aquifer protection

BMP design considerations for groundwater aquifer protection
Link to this table

BMP Group	Design Consideration
Bioretention	OK with proper caution for PSH
Filtration	OK with proper caution for PSH Open channels are OK, but polluted runoff must be adequately pretreated
Infiltration	Provide a 100-foot horizontal separation distance from wells and three-foot vertical distance from the water table No PSH runoff, unless treated by another practice, such as a filtering system Needed pre-treatment of all runoff except rooftop
Stormwater Ponds	Needed liner if A soils or active karst are present Pre-treat PSH runoff Provide a separation distance from well or water table to BMP
Constructed Stormwater Wetlands	May needed liner if A soils or active karst are present Pre-treat PSH runoff Provide a separation distance from well or water table to BMP
