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
