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
  • May need liner if A soils or active karst are present. The CSW permit requires a liner in areas of active karst.
  • Pre-treat PSH runoff
  • Provide a separation distance from well or water table to BMP
Constructed Stormwater Wetlands
  • May need liner if A soils or active karst are present. The CSW permit requires a liner in areas of active karst.
  • Pre-treat PSH runoff
  • Provide a separation distance from well or water table to BMP
