Trump rolls back Obama-era water protections. How will that affect California?

The Environmental Protection Agency is stripping protections for streams, wetlands, and groundwater nationwide.

Major water bodies will still be protected, but smaller ones that don’t flow year-round, especially in California and western states, will be open to pollution dumps.

This change is good news for farmers and real estate developers. But environmental activists, and even the agency’s science advisers, disagree.
