waterloop #86: Turning a Lake From Green to Clean with Mike Mallin, Dana Sargent, and Fred Royal

Updated: Mar 22, 2021

Many lakes around the country suffer from poor water quality in the same way as Greenfield Lake in Wilmington, N.C. - stormwater runoff into the lake from hard surfaces like roads, parking lots, and buildings causes nutrient pollution, algae growth, and even fish kills. But lakes can go from green to clean through a combination of science, partnerships, and measures to reduce runoff. The effort to restore Greenfield Lake is discussed in this episode with Mike Mallin, a Research Professor at the Center for Marine Sciences at the University of North Carolina Wilmington; Dana Sargeant, Executive Director of Cape Fear River Watch; and Fred Royal, Stormwater Services Manager with the City of Wilmington. They explain how universities, local government, a nonprofit, and an engineering firm are collaborating to target the sources of pollution and clean up a lake that is a community amenity and ecological gem. Listen to the audio podcast.

waterloop is made possible in part by grants from Spring Point Partners and the Walton Family Foundation.

Our Demonstration Farm For Clean Energy (Greene Co OHIO )investigates various sustainable, renewable and/or regenerative practices to support Human Rights and the UN SDGs. Our projects at this time include closing the loop of the nutrient cycle. We are collaborating with the Rich Earth Institute to educate the public and demonstrate right here in our home and farm, two new designs of toilets. The first is a modern, porcelain version appropriate for retrofit or new construction. This new design will allow for the capture and sustainable use of mineral-rich urine as crop fertilizer. The second, is a urine-diverting, dry composting, stand alone system appropriate for remote locations.

We would love to partner with you.

Water is vital to our health, communities, environment,

and economy. But there are tremendous challenges to the

quality and quantity of our water. Public awareness, concern, and action on water must increase.
