Northport, NY, November 2, 2018 – As one of the key building blocks of life, nitrogen is essential for the growth of all plants and animals. But when humans add too much of it to waterways serious problems can arise.

To help educate Long Islanders about the impact of nitrogen, New York Sea Grant (NYSG) and the Long Island Sound Study (LISS) presented a workshop this fall through the Long Island Sound Mentor Teacher program (LISMT). The LISMT program, now in its eighth year, provides teachers the opportunity to educate their peers and share successful classroom teaching strategies on issues that affect the health of Long Island Sound.

Coordinated by Anna Weshner-Dunning, LISS’s New York Outreach Coordinator, the “Be in the KNOW” (Keeping Nitrogen Out of our Waterways) workshop served as an introduction to nitrogen and water testing curriculum for some of Long Island and New York City’s science teachers. The workshop and presentations, conducted at Northport High School on September 22nd, were led by Torie Hehir, eighth grade Earth Science teacher for the Northport-East Northport school district, and Bob Mozer, seventh grade science teacher and science research club leader for the William Floyd School District. The pair introduced teachers to the basics of the nitrogen cycle and its significant impact on Long Island’s waterways.

Hehir explained that pure nitrogen is relatively inert. Before nitrogen can serve its vital purpose for plants and animals, it must be fixed via the nitrogen cycle into reactive nitrogen. Nitrogen fixation occurs when microorganisms convert nitrogen gas into usable nitrates. This reactive nitrogen is primarily produced for the agricultural industry and used domestically as fertilizer. When excess reactive nitrogen runs off into waterways, it can cause algal blooms, fish and turtle kills, eutrophication (excess nutrients causing a dense growth of plant life and death of animal life from lack of oxygen) and have impacts for groundwater and threaten the drinking water supply.

Mozer explained that compared to nature, humans produce over two times the amount of reactive nitrogen. In addition to surface fertilizer runoff, Long Island’s groundwater also receives nitrogen through the leaching pools commonly utilized in domestic septic systems. So, as the population of Suffolk County has increased in the past century—and with it the number of septic systems—so have levels of nitrogen in the groundwater. Older septic systems, unlike new ones installed today, were unable to filter out and prevent nitrogen from leaching into the groundwater.

After the classroom work, educators took a trip to Twin Ponds and Phragmites Park to get hands-on experience testing in the field. Teachers took surface and ground water samples to test for nitrogen and phosphorous.

Teachers left the training prepared with information, curricula, and hands-on demonstrations, as well as a field guide and equipment to help students “Be In the KNOW” about nitrogen.

Reflecting on the importance of bringing nitrogen education into the classroom, Weshner-Dunning said, “It’s important to bring this content into Long Island classrooms because nitrogen pollution is impacting the daily lives of teachers and students, whether they’re aware of it or not. This program is great because the teachers got really engaged, and there was a lot of dialogue about how they could implement these ideas into their classrooms.”

New York Sea Grant (NYSG), a cooperative program of Cornell University and the State University of New York (SUNY), is one of 33 university-based programs under the National Oceanic and Atmospheric Administration’s National Sea Grant College Program.

Since 1971, NYSG has represented a statewide network of integrated research, education and extension services promoting coastal community economic vitality, environmental sustainability and citizen awareness and understanding about the State’s marine and Great Lakes resources.

Through NYSG’s efforts, the combined talents of university scientists and extension specialists help develop and transfer science-based information to many coastal user groups—businesses and industries, federal, state and local government decision-makers and agency managers, educators, the media and the interested public.

The program maintains Great Lakes offices at Cornell University, SUNY Buffalo, SUNY Oswego and the Wayne County Cooperative Extension office in Newark. In the State's marine waters, NYSG has offices at Stony Brook University in Long Island, Brooklyn College and Cornell Cooperative Extension in NYC and Kingston in the Hudson Valley.

For updates on Sea Grant activities: www.nyseagrant.org has RSS, Facebook, Twitter, and YouTube links. NYSG offers a free e-list sign up via www.nyseagrant.org/nycoastlines for its flagship publication, NY Coastlines/Currents, which is published quarterly. Our program also produces an occasional e-newsletter,"NOAA Sea Grant's Social Media Review," via its blog, www.nyseagrant.org/blog.
