The Water Environment Federation (WEF) is recognizing 15 utilities for significantly reducing nutrient pollution, one of the leading problems for the health of waterways across the U.S. The utilities were selected through Nutrient Smart (NSmart), a collaboration between WEF and the U.S. Environmental Protection Agency (EPA) to recognize utilities that have demonstrated nitrogen or phosphorus reductions and developed robust community outreach programs.

NSmart also provides information and tools to help utilities make large reductions in nutrients and discharge cleaner water to the environment.

According to EPA, more than 100,000 miles of rivers and streams, close to 2.5 million acres of lakes and ponds, and more than 800 square miles of bays and estuaries are impacted by nitrogen and phosphorus pollution in the U.S. Nutrient pollution can also lead to algal blooms that are harmful to humans and animals.

“Nutrients are one of the most common pollution problems in U.S. waterways and WEF is glad to shine a light on utilities that are leading the way in reducing nitrogen and phosphorus and engaging their communities,” said WEF President Jamie Eichenberger. “NSmart joins other WEF programs like Utility of the Future and ReNEW which aim to create bold, aspirational calls to action to accelerate resource recovery.”

These utilities have reduced nutrients by at least 90 percent:

  • Nine Springs Treatment Facility - Madison Metropolitan Sewerage District (Wisconsin)
  • Upper Occoquan Service Authority (Virginia)
  • Town of Cary (North Carolina)
  • Dorsey Run Advanced Wastewater Treatment Plant (Maryland)
  • Stafford County Utilities (Virginia)

These utilities are working toward nutrient reduction of 30 to 70 percent and beginning outreach to the community on the issue:

  • Centennial Water and Sanitation District - Colorado

These utilities were additionally recognized as innovators for showcasing an outstanding example of treatment technology or leadership in nutrient management:
