Questions
Frequently asked questions
Is Garden Acres tap water safe to drink?
PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Garden Acres, PFOS 5.2 ng/L was measured above the 4 ng/L federal limit in EPA's 2024 testing. CALIFORNIA WATER SERVICE - STOCKTON (PWSID CA3910001) has a Purity Score of 72/100 (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 Garden Acres?
CALIFORNIA WATER SERVICE - STOCKTON (PWS ID CA3910001) is the public water system on record for Garden Acres, California, serving about 182,775 people. Confirm the utility on your water bill before acting on a specific finding.
Where does Garden Acres get its drinking water?
Surface water (primary source of record in EPA SDWIS).
Are PFAS "forever chemicals" in Garden Acres's water?
Yes. In EPA's UCMR 5 testing (2025-01-06 to 2026-03-10), PFOS was measured at 5.2 ng/L against a 4 ng/L federal limit. Reverse osmosis and filters certified to NSF/ANSI 53 for PFOA/PFOS reduce them at the tap.
Is there lead in Garden Acres's tap water?
Lead is not in Garden Acres'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 Garden Acres water report show?
PurityMap's current record for Garden Acres holds 31 findings: 1 above a reference and 30 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
