Questions

Frequently asked questions

Is Dale City tap water safe to drink?

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Dale City, PFOA 7.1 ng/L and PFOS 5.7 ng/L were measured above the 4 ng/L federal limit in EPA's 2024 testing. DALE CITY (PWSID VA6153625) has a Purity Score of 62/100 (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 Dale City?

DALE CITY (PWS ID VA6153625) is the public water system on record for Dale City, Virginia, serving about 72,062 people. Confirm the utility on your water bill before acting on a specific finding.

Where does Dale City get its drinking water?

Surface water (primary source of record in EPA SDWIS).

Are PFAS "forever chemicals" in Dale City's water?

Yes. In EPA's UCMR 5 testing (2023-09-04 to 2024-06-09), PFOA was measured at 7.1 ng/L against a 4 ng/L federal limit and PFOS was measured at 5.7 ng/L against a 4 ng/L federal limit. PFBS (8.5 ng/L, below the 2,000 ng/L EPA health advisory) and PFHxA (18 ng/L, below the 400,000 ng/L state limit) were also detected. PFBA (18.8 ng/L), PFHpA (6.1 ng/L) and PFPeA (21.9 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 Dale City's tap water?

Lead is not in Dale City'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 Dale City water report show?

PurityMap's current record for Dale City holds 31 findings: 2 above a reference, 2 detected within the reference, 3 detected with no limit and 24 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.

Every value is the published result from the cited public record. A reporting limit is the lowest level the method could reliably quantify; a non-detect is not a guarantee of zero.

Methodology: how we analyze water.

Data & methodologyHow we analyze waterData integrity policy

Something off with your water's smell, color or taste?

Start with the hot-or-cold tap check. Where Dale City reported something related, it's shown below.

Rotten-egg smell
Cloudy or milky water
Chlorine smell
Brown or yellow water
Metallic taste
Lead at Dale City: not detected (90th percentile, 2023–2025 monitoring period). Lead has no taste, so a taste neither shows nor rules it out.
