OMG, this is a picture of Wabasha MN....behind a huge algea bloom.....Also the home of the National Eagle Center......Come on Humans, pick up your garbage......Article states it is from tiny bits of plastic etc...
Although some improvement in other pollutants. so good news and bad.

kb - Troubling news. Phosphorus is the primary culprit in algae blooms. The main source is from agricultural runoff (e.g., animal waste and fertilizers) and the rest is from leaking septic systems and household wastewater that wastewater treatment plants were never designed to remove. Humans excrete phosphorus from the foods we eat. In addition, most automatic dishwashers use trisodium phosphate as the main cleaning ingredient, but laundry detergent was reformulated long ago to remove phosphates. However, wastewater from washing machines also contains the very small clothing fibers the article talked about and possibly some of the microplastics. Again, wastewater treatment plants were never designed to remove such tiny particles. (As an aside, many new washing machine tubs and clothing have been impregnated with silver that acts like an antibacterial to suppress odors. Silver is very toxic to aquatic life.) It's a big problem with big economic and human impacts, but solutions are doable if we can find the will.
T40 You are obviously more informed than me....Thank you for your concern. I don't have a dishwasher anymore, needed the space for drawers.......much more than that I see......thank you for the information.
