Choose your situation
Older buildings may have lead service lines, solder or fixtures. Lead is not in Andover’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 Andover’s record (PFBA 11.1 ng/L). 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.

How PurityMap reads Andover’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. Andover · PWSID MN1020034 · Purity Score 100/100 (Excellent) · Confidence: moderate · Assessed at the water-system level
