Questions
Frequently asked questions
Is Storrs tap water safe to drink?
PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Storrs, PFOS 5 ng/L was measured above the 4 ng/L federal limit in EPA's 2024 testing; the lead 90th-percentile result was 7.6 µg/L against the 15 µg/L action level. UNIVERSITY OF CONNECTICUT - MAIN CAMPUS (PWSID CT0780021) has a Purity Score of 65/100 (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 Storrs?
UNIVERSITY OF CONNECTICUT - MAIN CAMPUS (PWS ID CT0780021) is the public water system on record for Storrs, Connecticut, serving about 27,199 people. Confirm the utility on your water bill before acting on a specific finding.
Where does Storrs get its drinking water?
Surface water (primary source of record in EPA SDWIS).
Are PFAS "forever chemicals" in Storrs's water?
Yes. In EPA's UCMR 5 testing (2023-03-27 to 2024-06-21), PFOS was measured at 5 ng/L against a 4 ng/L federal limit. PFBA (5 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 Storrs's tap water?
UNIVERSITY OF CONNECTICUT - MAIN CAMPUS's most recent lead 90th-percentile result (2024–2026) was 7.6 µg/L, below the 15 µg/L action level. That figure comes from sampled homes; lead usually enters from a building's own pipes and fixtures, so only a test at your tap tells you what you drink.
What does the latest Storrs water report show?
PurityMap's current record for Storrs holds 31 findings: 1 above a reference, 1 detected within the reference, 1 detected with no limit and 28 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. Prepared with AI assistance and reviewed by the PurityMap Editorial Team before publication.
Something off with your water's smell, color or taste?
Start with the hot-or-cold tap check. Where University of Connecticut reported something related, it's shown below.
- Rotten-egg smell
- Cloudy or milky water
- Chlorine smell
- Brown or yellow water
- Metallic taste
Lead at University of Connecticut: 7.6 µg/L (90th percentile, 2024–2026 monitoring period (still open)). Lead has no taste, so a taste neither shows nor rules it out.
