The Cape has a dirty water problem. The main culprit? Pee. Over the years, waterways around Cape Cod have been increasingly impacted by peoples' septic tanks, which leach nitrogen and phosphorus -- from urine -- into the Cape's ground water. This, in turn, leads to unhealthy water quality and toxic algae blooms that are dangerous for humans and wildlife alike.

Municipalities around the Cape are now looking for solutions that will keep their tourist-attracting bodies of water clean and pee-free. Among them, as WBUR Climate and Environment Correspondent Barbara Moran tells us, is one innovative method known as pee-cycling.
