Unsafe water with serious health risks.
Exceeds 1 EPA limits and 7 recommended standards.
Contaminants exceeding EPA limits
What it means: This refers to substances in the water that are found at levels higher than what the EPA allows. The EPA (Environmental Protection Agency) is a U.S. government agency that sets legal limits for harmful contaminants to protect public health. Exceeding these limits means the water may pose health risks based on federal safety standards.

How to best protect from water pollution?
Reduce your water pollution exposure in California
Carbon Filter
Carbon filters are effective at removing many common contaminants including chlorine, sediment, volatile organic compounds (VOCs), and improves taste and odor.
Reverse Osmosis
Reverse osmosis systems can remove up to 99% of dissolved contaminants from water including heavy metals, fluoride, nitrates, and arsenic.
