MND - Mitigated Negative Declaration

Document Description
The Metropolitan Water District of Southern CA has conducted an environmental review for the application of an aquatic pesticide (copper sulfate) to its reservoirs in San Bernardino County, CA: Copper Basin and Gene Wash (Project). Metropolitan proposes to apply copper sulfate on an as-needed basis to control algal blooms so that such blooms do not degrade drinking water quality through elevated taste and odor problems, production of algal toxins, and water treatment plant filter clogging.
