The Water Environment Federation (WEF) has recognised 15 utilities for significantly reducing nutrient pollution, one of the leading problems for the health of waterways across the US.
The utilities were selected through Nutrient Smart (NSmart), a collaborative between WEF and the US Environmental Protection Agency (EPA) to recognise utilities that have demonstrated nitrogen or phosphorus reductions and developed robust community outreach programmes.
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 US nutrient pollution can also lead to algal blooms that are harmful to humans and animals.
Jamie Eichenberger, president of WEF, commented: “Nutrients are one of the most common pollution problems in US 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. NSmart joins other WEF programmes like Utility of the Future and ReNEW which aim to create bold, aspirational calls to action to accelerate resource recovery.”
