Conservatives, can you explain how weakening the Clean Water Act is beneficial?

In a 5-4 decision Tuesday, the U.S. Supreme Court weakened rules on the discharge of raw sewage into water supplies. The CWA is the primary law governing pollution control and water quality in the United States, and this ruling seems primed to allow cities to dump significantly more sewage in various water sources, potentially degrading water quality standards.

In the dissenting opinion, even Amy Coney Barrett stated that the court offered "nothing to substantiate" a "puzzling" ruling.

I'd like those on the right to explain how this ruling does not make average Americans' lives less safe and less healthy—a contrast to the rhetoric espoused by Robert F. Kennedy Jr. and others.

Thank you for your time.
