Scientists and engineers have identified the causes of nitrogen pollution and have developed proven solutions for managing wastewater and stormwater and reducing the impacts of fertilizer use.
Conventional septic systems were designed nearly a century ago to treat bacteria from human waste but they are not as effective at treating nitrogen. New onsite septic system technologies, capable of safely removing far more nitrogen from human waste exist, but they are not currently available for use in Connecticut. Just as we upgraded wastewater treatment facilities to reduce nitrogen before it is discharged to waterways, we can use 21st century technologies for septic systems to treat pollution before it enters groundwater and makes its way to harbors and bays. Additionally, we can do a better job of managing the way we use fertilizers by changing landscaping and agricultural practices to protect and restore healthy coastal waters.
Because nitrogen pollution sources and coastal water conditions differ between communities, not all solutions are appropriate for every situation. With a variety of options, water managers and communities can target nitrogen pollution sources with effective solutions.
