About Anaheim's Water

PFAS Water Contamination: What Anaheim Residents Should Know

PFAS have been detected in Anaheim's water supply at 3.7 parts per trillion. Health agencies including the EPA have set limits on certain PFAS compounds in drinking water due to concerns about long-term exposure. While municipal treatment reduces many contaminants, standard water treatment does not fully remove PFAS. Point-of-use reverse osmosis filtration is the most effective home solution confirmed to remove PFAS at the 99%+ level.

Anaheim Hard Water: Effects on Your Home

Hard water conditions in Anaheim (10.4 GPG) can leave white mineral deposits on fixtures, reduce soap lather, and gradually damage water-using appliances. Water heaters are particularly vulnerable: scale insulates the heating element, raising energy costs and reducing lifespan. A water softener exchanging calcium and magnesium for sodium eliminates scale formation throughout the home. For households concerned about sodium in drinking water, pairing a softener with an RO system at the kitchen tap is the standard approach.
