The goal of this project is to proving they can reduce nitrogen by more test these systems in a neighborhood with real than 95%. In昀氀uent is how much nitrogen is 昀氀owing into the septic tank. E昀昀luent is how much nitrogen is coming out of the NitROE system. Municipal treatment plants target 3 mg/L Total Nitrogen (mg/L) from 12 of the NitROE systems as of September 2023 as reported by the Massachusetts Alternative Septic System Test Center (MASSTC) and the U.S. Environmental Protection Agency (US EPA). Median Data BCWC worked closely with our partners at the US EPA, USGS, The Nature Conservancy, and the Town of Barnstable to implement this groundbreaking research pilot. “Performance is really impressive. We are consistently seeing lower than 10 mg/L in the e昀昀luent, frequently it is lower than that” says Dr. Sara Wigginton from MASSTC, who leads the monthly sampling of the Shubael NitROE systems. Dr. Wigginton further states that “the NitROE system is a strong candidate for the enhanced, innovative and alternative system that Cape Cod towns will be using to meet the new MassDEP regulations.” RIGHT: Dr. Wigginton with her colleagues collecting samples from the Shubael Pond Project NitROE systems.
