That's a lot of phosphorus. Someday people won't believe we just dumped untreated manure into the environment, in the same way we now cringe at the thought of doing the same with human waste.

Ben Maas @masbenmaas.bsky.social · 6d

From Dr Chris Jones @theswinerepublic.bsky.social

"The waste produced by livestock [beef cattle, dairy cows, hogs, chickens & turkeys] in the St. Croix River watershed is equivalent to 3.25 million more people living in the region."

US EPA has canceled grants related to PFAS transport through soils. Biosolids and composts can be contaminated with PFAS, so understanding how these compounds move after being applied to soils is critical to the responsible recycling of nutrients.

EPA cancels PFAS research grants to Maine organizations

Maine organizations researching PFAS are the latest groups to face sudden grant terminations, this time from the Environmental Protection Agency.
