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
