The New York Times explained what this means:
The new water rule for the first time in decades allow landowners and property developers to dump pollutants such as pesticides and fertilizers directly into hundreds of thousands of waterways, and to destroy or fill in wetlands for construction projects.
“This will be the biggest loss of clean water protection the country has ever seen,” said Blan Holman, a lawyer specializing in federal water policy at the Southern Environmental Law Center. “This puts drinking water for millions of Americans at risk of contamination from unregulated pollution. This is not just undoing the Obama rule. This is stripping away protections that were put in place in the ’70s and ’80s that Americans have relied on for their health.”
Mr. Holman also said that the new rule exemplifies how the Trump administration has dismissed or marginalized scientific evidence. Last month, a government advisory board of scientists, many of whom were handpicked by the Trump administration, wrote that the proposed water rule “neglects established science.”
But farmers and fossil fuel groups supported the change.
Senator, are "farmers and fossil fuel groups" the only ones that matter? What about the rest of us?
