Questions
Frequently asked questions
Is Kettering tap water safe to drink?
PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Kettering, PFOS 9.6 ng/L (limit 4 ng/L) and PFHxS 10.7 ng/L (limit 10 ng/L) were measured above their limits in EPA's 2024 testing. MONTGOMERY COUNTY WATER SERVICES 1 PWS (PWSID OH5701315) 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 Kettering?
MONTGOMERY COUNTY WATER SERVICES 1 PWS (PWS ID OH5701315) is the public water system on record for Kettering, Ohio, serving about 150,207 people. Confirm the utility on your water bill before acting on a specific finding.
Where does Kettering get its drinking water?
Surface water (primary source of record in EPA SDWIS).
Are PFAS "forever chemicals" in Kettering's water?
Yes. In EPA's UCMR 5 testing (2023-07-19 to 2024-04-17), PFOS was measured at 9.6 ng/L against a 4 ng/L federal limit and PFHxS was measured at 10.7 ng/L against a 10 ng/L federal limit. PFBS (3.2 ng/L, below the 2,000 ng/L EPA health advisory) and PFHxA (5 ng/L, below the 400,000 ng/L state limit) were also detected. PFPeA (5.2 ng/L) was also detected; it has 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 Kettering's tap water?
Lead is not in Kettering'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 Kettering water report show?
PurityMap's current record for Kettering holds 31 findings: 2 above a reference, 2 detected within the reference, 1 detected with no limit and 26 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.

Something off with your water's smell, color or taste?
Start with the hot-or-cold tap check. Where Montgomery County Water Services reported something related, it's shown below.
- Rotten-egg smell
- Cloudy or milky water
- Chlorine smell
- Brown or yellow water
- Metallic taste
Lead at Montgomery County Water Services: not detected (90th percentile, 2025 monitoring period). Lead has no taste, so a taste neither shows nor rules it out.
