Water Quality Problems and Sources from 303(d) ListWater Quality Problems and Sources from 303(d) List
- Chloride: Road salt for deicing
- Copper: Runoff from roads, parking lots
- Nutrients (Nitrate, Nitrogen, Phosphorus): Wastewater treatment plants, lawn care, atmospheric deposition, urban runoff and stormsewers
- Sediments and solids: Construction activities, erosion, urban runoff, deicing operation
- Habitat Alterations: Channelization, Streambank modification/destabilization
- Flow Alterations: Dam construction, flow regulation/modification
