Questions

Frequently asked questions

Is Rio Rico tap water safe to drink?

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Rio Rico, PFOS 40.9 ng/L (limit 4 ng/L), PFOA 10 ng/L (limit 4 ng/L) and PFHxS 10.9 ng/L (limit 10 ng/L) were measured above their limits in EPA's 2024 testing. LIBERTY WATER RIO RICO (PWSID AZ0412011) has a Purity Score of 57/100 (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 Rio Rico?

LIBERTY WATER RIO RICO (PWS ID AZ0412011) is the public water system on record for Rio Rico, Arizona, serving about 17,960 people. Confirm the utility on your water bill before acting on a specific finding.

Where does Rio Rico get its drinking water?

Groundwater (primary source of record in EPA SDWIS).

Are PFAS "forever chemicals" in Rio Rico's water?

Yes. In EPA's UCMR 5 testing (2023-04-17 to 2024-04-11), PFOS was measured at 40.9 ng/L against a 4 ng/L federal limit, PFOA was measured at 10 ng/L against a 4 ng/L federal limit and PFHxS was measured at 10.9 ng/L against a 10 ng/L federal limit. PFBS (20 ng/L, below the 2,000 ng/L EPA health advisory) and PFHxA (4 ng/L, below the 400,000 ng/L state limit) were also detected. PFBA (7 ng/L) and PFPeA (3 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 Rio Rico's tap water?

Lead is not in Rio Rico'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 Rio Rico water report show?

PurityMap's current record for Rio Rico holds 31 findings: 4 above a reference, 2 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.
