Questions
Frequently asked questions
Is Highland tap water safe to drink?
PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Highland, PFOS 12 ng/L and PFOA 9 ng/L were measured above the 4 ng/L federal limit in EPA's 2024 testing. EAST VALLEY WATER DISTRICT (PWSID CA3610064) has a Purity Score of 56/100 (confidence: moderate), assessed at the water-system level and computed only from contaminants that were measured. Water can change in your own pipes, so a certified test is the only way to know what comes out of your tap.
Who provides tap water in Highland?
EAST VALLEY WATER DISTRICT (PWS ID CA3610064) is the public water system on record for Highland, California, serving about 108,600 people. Confirm the utility on your water bill before acting on a specific finding.
Where does Highland get its drinking water?
Surface water (primary source of record in EPA SDWIS).
Are PFAS "forever chemicals" in Highland's water?
Yes. In EPA's UCMR 5 testing (2024-10-09 to 2025-07-02), PFOS was measured at 12 ng/L against a 4 ng/L federal limit and PFOA was measured at 9 ng/L against a 4 ng/L federal limit. PFBS (8.9 ng/L, below the 2,000 ng/L EPA health advisory), PFHxA (4.7 ng/L, below the 400,000 ng/L state limit) and PFHxS (4 ng/L, below the 10 ng/L federal limit) were also detected. PFHpA (3.1 ng/L) and PFPeA (4.7 ng/L) were also detected; they have no federal or state limit. Reverse osmosis and filters certified to NSF/ANSI 53 for PFOA/PFOS reduce them at the tap.
Is there lead in Highland's tap water?
Lead is not in Highland's current published record. Lead usually enters from a building's own pipes and fixtures, so a certified home test is the way to know yours.
What does the latest Highland water report show?
PurityMap's current record for Highland holds 31 findings: 3 above a reference, 3 detected within the reference, 2 detected with no limit and 23 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
