The short answer for Guasti (91764)
Ontario tap water has PFPeA above EPA guidelines at 1.6× the limit (tested August 2023). See the full report with all tested compounds and filter options.
The health risk for Ontario
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.
- PFPeA above limit.

Certified Filters for Ontario Tap Water
PFPeA (a PFAS 'forever chemical') was detected above EPA limits. These filters are independently certified to reduce common drinking-water contaminants.
Pitcher filter
Epic Pure XP Water Filter Pitcher
NSF-certified dual-layer filtration reduces 70+ contaminants including PFAS, lead, chlorine, microplastics, and bacteria.
NSF/ANSI 42, 53, 401 & P473Removes 99.99% PFASMade in USABPA-free
PFAS detected in 91764 · What you can do
Here's what actually removes PFAS from your water
The right filter eliminates PFAS at the tap. But not all filters do - and the type you choose matters for your home.
Common pitchers like Brita do not remove PFAS. You need a filter independently certified to NSF P473 (for pitcher filters) or NSF/ANSI 58 (for reverse osmosis systems). All three options below carry the relevant certification.
Certified PFAS filter types - how they differ
Certified Pitcher
Removes PFAS (99%+)
No installation, works today
Lowest upfront cost (~$70)
Must refill manually
Filters only what you pour in - not cooking water
Reverse Osmosis More complete
Removes PFAS + lead, arsenic, nitrates & more
Always-on - no refilling ever
Noticeably better tasting water
Filters drinking & cooking water automatically
Higher upfront cost ($200-$400)

Frequently Asked Questions about ZIP 91764 Tap Water
What contaminants are above EPA limits in ZIP 91764?
ZIP 91764 has PFPeA above EPA health guidelines in the latest available data at 1.6x the EPA guideline. The full table on this page lists every tested compound and its measured level.
Will boiling ZIP 91764 tap water remove PFPeA?
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 PFPeA?
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 91764?
Public records identify ONTARIO MUNICIPAL UTILITIES COMPANY as a primary water system associated with ZIP 91764. Service boundaries can vary by address, so confirm exact service with the utility.
When was ZIP 91764 tap water last tested?
The most recent test date used in this report is March 2024. EnviroClarity last refreshed this page on 2026-05-04.
Where can I find the official water quality report for ZIP 91764?
Every U.S. public water system is required to publish an annual Consumer Confidence Report (CCR). Contact ONTARIO MUNICIPAL UTILITIES COMPANY or visit their website for the latest official report covering ZIP 91764. The EPA also maintains a national CCR locator.
