• Overview: Best Management Practices to minimize the migration of waste constituents applied through irrigation are being evaluated.

 
• Goal: Develop irrigation guidelines and management standards to minimize the off-site impacts of wastewater irrigation.

 
• Wastewater irrigation is a common terminal treatment practice for liquid municipal, industrial and agricultural waste. Management guidelines established for freshwater irrigation are often not relevant for wastewater irrigation. Field and lysimeter studies are underway to evaluate the influence of irrigation scheduling methods, system calibration, and other practices such as controlled drainage and vegetative field borders on surface and shallow ground water quality.
