Low Cost Retrofits for Nitrogen Removal at Wastewater Treatment Plants (WWTPs) in the Upper Long Island Sound (LIS) Watershed study is the final report for a study that was designed to assess the feasibility and cost-efficiency of installing low-cost biological nitrogen removal retrofits at select WWTPs in the upper LIS watershed (Massachusetts, New Hampshire, and Vermont).
Funding for this study was awarded by US EPA to the New England Interstate Water Pollution Control Commission (NEIWPCC) in partnership with the Long Island Sound Study. NEIWPCC entered into a contract with Jeanette Brown of JJ Environmental, LLC to conduct the study.see LIS Low Cost Retrofit Final Report – March 2015 (revised) | Appendix
