The health risk for Lake Arrowhead

PFAS ('forever chemicals') have been detected above EPA limits in this water system's most recent tests. These synthetic chemicals do not break down in the body and are linked to a range of health effects. A certified filter is strongly recommended.

Frequently Asked Questions about ZIP 92321 Tap Water

What contaminants are above EPA limits in ZIP 92321?

ZIP 92321 has 8 contaminants above EPA health guidelines in the latest available data, including PFOA at 2.8x the EPA guideline. The full table on this page lists every tested compound and its measured level.

Will boiling ZIP 92321 tap water remove PFOA?

No. Boiling does not remove PFAS, and the compounds can actually become more concentrated as water evaporates. To reduce PFAS at home, use a filter independently certified to NSF/ANSI P473 (activated-carbon pitcher or under-sink) or NSF/ANSI 58 (reverse osmosis).

Do basic pitcher filters remove PFOA?

Most basic pitcher filters are only certified to NSF/ANSI 42 or 53, which do not cover PFAS. Look for a filter independently certified to NSF/ANSI P473 (activated-carbon pitcher or under-sink) or NSF/ANSI 58 (reverse osmosis) on the spec sheet.

Who provides tap water in ZIP 92321?

Public records identify CLAWA as a primary water system associated with ZIP 92321. Service boundaries can vary by address, so confirm exact service with the utility.

When was ZIP 92321 tap water last tested?
