The Bay Needs Healthy Streams to Thrive

57% of streams are in poor or very poor condition.

'Dead Zones'

Nitrogen, phosphorus enter the Bay from agricultural runoff and discharges, wastewater treatment plant discharges, urban and suburban runoff and septic tank discharges, and air deposition. These pollutants cause 'dead zones' which quickly kill any plant or animal in the vicinity.

The EPA created an initiative to decrease these pollutants by 2025.
