Water QualityWater Quality
– Sediment (construction sites)– Bacteria (pet wastes, septic systems)– Lawn chemicals (fertilizers and
pesticides)– Oil , trash, salt & heat (from roads &
parking lots)

Agricultural RunoffAgricultural Runoff
• Sediment• Fertilizers/pesticides• Bacteria (animal waste)
The resultThe result
• Increase runoff volumes and velocities • Downstream flooding• Eroded streambanks
