Study finds changing dissolved organic carbon in Maine lakes key to maintaining drinking water quality

Monitoring concentrations of dissolved organic carbon in Maine lakes before and after severe rainstorms could inform management strategies to help ensure consistent, high-quality drinking water, according to University of Maine researchers.

In their study, working with local drinking water districts, Kate Warner and Jasmine Saros, researchers in UMaine's Climate Change Institute and the School of Biology and Ecology, found that increasingly frequent and extreme rain events can contribute to short-term abrupt changes in the quantity and quality of lakes' dissolved organic carbon, which is derived from leaves, pine needles and other terrestrial debris in watershed runoff.

[...] By sampling dissolved organic carbon in six Maine lakes before and after five severe rainstorms, the researchers found three response patterns. Some lakes had an initial spike in dissolved organic carbon that returned to prestorm levels within days. The largest lakes sustained no changes in the concentrations of dissolved organic carbon.

    The key to drinking water quality has less to do with virtue signalling ("increasingly frequent and extreme rain events" is a tip-off we're dealing with millennial scientists here) and more to do with filtering out the fish piss. I'm surprised these millennial scientists didn't try to determine how many genders Maine lake fish have.

    That's an easy one: zero. Only words and sapient and sentient beings have gender. Fish aren't words, though fish is a word, and are neither sapient nor sentient. The fish probably have 2 primary sexes though.
