Most controllable Nitrogen (80%) in watersheds comes from residential wastewater systems. Adjustments in behavior and technology can significantly reduce the amount of Nitrogen entering these systems from homes.Options
Healthy plants need Nitrogen, whether from natural sources or fertilizers we apply. Improper application can result in Nitrogen from the fertilizer percolating into groundwater or running off during storms.Options
These underground systems collect and treat wastewater. Processes in the septic system remove harmful bacteria but do not remove Nitrogen. They require regular maintenance and last 20 to 30 years.Options
