Agricultural activities contribute significantly to water pollution through runoff containing fertilizers, pesticides, and sediments. Learn about effective treatment solutions.

Agricultural Runoff Characteristics

• Nutrients: Nitrogen, phosphorus from fertilizers
• Pesticides: Herbicides, insecticides, fungicides
• Sediments: Soil erosion, organic matter
• BOD: From animal waste, crop residues
• Coliform bacteria: From livestock operations

Treatment Technologies

Vegetated Treatment Systems

• Grassed waterways – slow runoff, trap sediments
• Filter strips – vegetated areas adjacent to fields
• Riparian buffers – trees and vegetation along streams
• Constructed wetlands – biological treatment

Chemical Treatment

• Alum treatment for phosphorus removal
• Wick harrow for nitrogen reduction
• pH adjustment for metal-contaminated runoff

Retention Ponds

• Sedimentation basins
• Detention ponds for flow equalization
• Duck ponds for polishing

Best Management Practices (BMPs)

• Conservation tillage
• Crop rotation and cover crops
• Precision agriculture
• Livestock fencing from waterways
• Proper pesticide application timing

Regulatory Compliance

Meeting TMDL requirements:

• Total maximum daily load allocations
• Nutrient management plans
• Sediment reduction targets
