Interesting chart on U.S. Water quality

NOTE The lines on bacterial/Nitrates, parasites going down (somewhat) BUT - Disinfecting products going up as is PFAS particles (Perfluorooctanesulfonic acid as in non-stick pots/pans and many other applications)

Article is a look into how water is tested in the U.S. -

Current technology can remove most contaminants, says David Sedlak, an environmental engineer at the University of California, Berkeley. Those include microbes, arsenic, nitrates and lead. “And then there are some that are very difficult to degrade or transform,” such as industrial chemicals called PFAS.

Smaller communities, especially, can’t always afford top-of-the-line equipment or infrastructure overhauls to, for example, replace lead pipes. So Reckhow’s facility is testing approaches to help communities address water-quality issues in affordable ways.

Some researchers are adding technologies to deal with new, potentially harmful contaminants. Others are designing approaches that work with existing water infrastructure or clean up contaminants at their source.

DREAD to think what an updated 2016 to today's chart would look like
