The Trump administration has weakened an Obama-era rule aimed at stopping coal plant pollution that has contaminated streams, lakes and underground aquifers.

FILE - This March 22, 2019, file photo shows Mount Rushmore in Keystone, S.D. The Trump administration on Thursday, June 18, 2020, rejected imposing federal drinking-water limits for a chemical used in fireworks and other explosives and linked to brain damage in newborns. The contaminant is perchlorate, a component in rocket fuel, ammunition and other explosives, including fireworks. The Associated Press found one high-profile example of that on Thursday, reviewing a 2016 U.S. Geological Survey report that links high levels of perchlorate contamination in the water at Mount Rushmore national memorial with past years of fireworks displays there.
