Your tap can differ from the city record
The record describes water leaving treatment and samples across the system. Pipes, solder and fixtures inside a building can add lead the record can’t see, especially in older buildings with lead service lines.

Choose your situation
Older buildings may have lead service lines, solder or fixtures. Lead is not in Ramsey’s published record, so only a tap test tells you. Test first-draw water, then filter if needed.
1 of 29 PFAS tested was detected in Ramsey’s record (PFOA 5.2 ng/L); 1 above its limit. If PFAS matters to you, a filter certification names each compound it covers.
Most utilities keep chlorine or chloramine in the pipes. A carbon filter certified for taste and odor reduces either; your utility can tell you which it uses.
Your utility’s annual water quality report usually lists hardness; a test strip also measures it.
Reverse osmosis reduces many dissolved contaminants, including lead and minerals, at a single faucet, with some water sent to drain.

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Ramsey, PFOA 5.2 ng/L was measured in one EPA sample, above the 4 ng/L limit EPA set in 2024 (not a violation: the limit is judged on a yearly average, due 2029). RAMSEY WATER COMPANY, INC. (PWSID IN5231005) has a Purity Score of 69/100 (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. What we found →

Are PFAS "forever chemicals" in Ramsey's water?
Yes. In EPA's UCMR 5 testing (2024-03-26 to 2024-09-11), PFOA was measured at 5.2 ng/L in one EPA sample, above the 4 ng/L limit EPA set in 2024. That limit is judged on a yearly average, and water systems have until 2029 to meet it, so a single sample is not a violation. Reverse osmosis and filters certified to NSF/ANSI 53 for PFOA/PFOS reduce them at the tap. What we found →

How PurityMap reads Ramsey’s water
- 01Source data
EPA SDWIS, EPA UCMR 5 and utility reports, each dated and linked.
- 02Normalize
Units converted to one basis; a non-detect kept distinct from zero.
- 03Classify
Each result tagged by reference type: MCL, action level, screening level or aesthetic.
- 04Compare to the named reference
Every value sits against its own reference, never a blended one.
- 05Score
Measured subjects summarised at the water-system level; an open health-based violation caps the score.
- 06Match treatment
Treatment is matched to what was found; a product is called certified only when its current certification names it.
What the Purity Score means: a summary of this water system’s published record, capped while a health-based violation is open. It is not a test of any tap. RAMSEY WATER COMPANY, INC. · PWSID IN5231005 · Purity Score 69/100 (Fair) · Confidence: moderate · Assessed at the water-system level
