Nitrogen Pollution in Long Island Sound Continues to Decline

Jul 16th, 2014 | By | Category: Long Island Sound, Water

A new report says nitrogen pollution discharged into Long Island Sound continues an overall decline. That’s good news for marine life because too much nitrogen can fuel the growth of algae, which dies, settles on the ocean floor, and decays, using up oxygen in the process.

During summer, that can lead to a condition called hypoxia. “Hypoxia is a low-oxygen dead zone in the water,” said Kurt Johnson, executive director of Save the Sound, an environmental advocacy group.

Local sewage plant discharges up slightly

Nitrogen discharges from municipal sewage treatment plants increased only slightly in 2013 from the previous year, and the state remains on track to meet its nitrogen reduction goals for 2014, the state Council on Environmental Quality said in its recently updated report.

About 4,000 tons of nitrogen flowed into Long Island Sound and rivers that discharge into the Sound from 80 municipal treatment plants in 2013, down from 7,500 tons a decade ago.
