On Blog: Municipal Officials Conference: Managing Cesspools & Septic Systems to Protect LI’s Waters
Nonpoint Education for Municipal Officials (NEMO) - News
Stony Brook, NY, April 17, 2014 - On March 25, 2014, at the scenic Old Bethpage Restoration Village on Long Island, approximately 130 coastal managers, septic and cesspool company business owners, researchers, water quality professionals, elected officials, engineers and concerned citizens gathered to hear experts deliver much needed information about the state of Long Island’s cesspools and septic systems and where we go from here. Kicking off the morning slate of speakers was Eileen Keenan, Manager of New York Sea Grant’s Nonpoint Education for Municipal Officials Program. Keenan’s clear overview of the issue got right to the point: whereas much of Nassau County’s population utilizes sewers, most of Suffolk County’s population uses on-site wastewater treatment systems (OWTS), many of them situated on poor soils, inadequately built, and in need of upgrading or replacement. Pathogens and nitrogen from OWTS travel from septic systems through groundwater and ultimately impair the surface water.  Keenan called for better integration of waste water management and efforts to address coastal hazards and sea level rise.

More technical specifics about OWTS – what they do and how they generate pollutants – came from George Loomis, Director of the University of Rhode Island New England Onsite Wastewater Training Center. With numerous slides and schematics, he introduced the audience to some of the techniques and products now available and being used in nearby Rhode Island where development abuts the water bodies and the soil types are similar to those on Long Island. Loomis and colleague Lorraine Joubert, the Director of URI’s Nonpoint Education for Municipal Officials program continued the discussion into the afternoon session as they discussed 30+ years of mitigating the impacts of OWTS.  

Suffolk County’s public health engineer, Walter Hilbert, outlined what is transpiring at the county level as Suffolk looks at major systems in communities in the Peconic Estuary, Long Island Sound and Great South Bay on a case-by-case basis. The county will look at groundwater modeling and wastewater planning to produce maps and evaluate the costs in very real terms: in dollars per pound of nitrogen. The county is working with Stony Brook University to develop the NY State Water and Environmental testing lab to research and commercialize the next generation of wastewater treatment technology.

Architect Gynnis Berry, the director of Peconic Green Growth, educated the audience by showing GIS maps of the east end of Long Island, emphasizing how the maps show just how little time it takes for wastewater from individual septic systems to enter the waterways.

Kristina Heinemann from the US Environmental Protection Agency, Region 2, discussed how the EPA has prepared guidelines for several models of on-site systems. These range from individual homeowners who monitor their own system maintenance (and sometimes “flush and forget”) to larger scale systems that are maintained with service contracts, to those companies and businesses known as RMEs (responsible management entities) who have trained personnel and operating permits to keep systems working at peak performance. The EPA has numerous fact sheets about septic systems and maintenance in its series “Clean Water Starts at Home.”

Nassau County Department of Public Works was also represented at the conference with a discussion of the all-important inter-municipal partnerships that must be developed to address OWTS impacts.

An afternoon Q & A with the speakers and closing remarks of the conference point to the fact that municipal officials, water-protection entities, and septic-related business owners agree that working together and getting information and training is key to effective mitigation of OWTS impacts.

The conference was sponsored by the Hempstead Harbor Protection Committee, Friends of the Bay, the Manhasset Bay Protection Committee, the Oyster Bay/ Cold Spring Harbor Protection Committee, The Town of Oyster Bay, and New York Sea Grant. It was made possible by a grant from the Long Island Sound Futures Fund and the Long Island Sound Study.

More Info: New York Sea Grant

New York Sea Grant (NYSG), a cooperative program of Cornell University and the State University of New York, is one of 33 university-based programs under the National Sea Grant College Program (NSGCP) of the National Oceanic and Atmospheric Administration (NOAA). The NSGCP engages this network of the nation’s top universities in conducting scientific research, education, training and extension projects designed to foster science-based decisions about the use and conservation of our aquatic resources. Through its statewide network of integrated services, NYSG has been promoting coastal vitality, environmental sustainability, and citizen awareness about the State’s marine and Great Lakes resources since 1971.

For updates on Sea Grant activities: www.nyseagrant.org has RSS, Facebook, Twitter, and YouTube links. NYSG also offers a free e-list sign up via www.nyseagrant.org/coastlines for NY Coastlines, its flagship publication, which, in 2014, merges with the program's e-newsletter, Currents. NY Coastlines is published several times a year.
