trump Declares His Support for Clean Water and Clean Air After the 2018 Midterms

It's already done. Fint's water is currently safe to drink, and continuing to improve due to changes already in progress.

There are an estimated 12,000 lead pipes still in use. April of 2018. Motherjones.com

Oh, to be sure, the work is not complete. The lead levels in the water are above 0, so there's still work to be done. However, the levels are now low enough for the water to be drinkable.

Michigan was well on the way to fixing this problem without Trump. If Congress sends funds that help it get finished faster, cool. They're helping, not DOING.

As for clean air and water in general, there are regulations in place to keep them clean. Maybe instead of doing away with those regulations, you make sure they're enforced? Making pollution legal sounds counterproductive. Just sayin'.

There is no safe level of lead, that is to say, the safe level of lead is 0.

A bunch of Federal funds went to Michigan to help with the needed work.

The New York Times reports 46 completed rollbacks and 30 in progress of rules and regulations that protect climate and health. He ran on doing this. He rolled back radiation exposure rules with affects medical workers, miners, and nuclear plant operators. He has a record of canceling "burdensome" regulations that he claims are expensive and unnecessary that protect workers health and the environment.

trump saying he wants the cleanest air and cleanest water is basically trump saying he will undo a bunch of things he has done since he came into office.
