Find out if your building has a lead service line Water utilities keep an inventory of service-line materials. Ask City of Kerrville whether your address is on it before you replace pipes.

Is this right for my home?
Choose your situation Your situation I live in an older building I care about PFAS My water tastes of chlorine I have scale or hard water I want the broadest reduction
Your path: I live in an older building Lead from plumbing is the main question Older buildings may have lead service lines, solder or fixtures. Kerrville’s record shows lead at 3.34 µg/L (15 µg/L federal action level). Test first-draw water, then filter if needed.
Look for Lead reduction: NSF/ANSI 53 (lead)
How to test your tap →
Your path: I care about PFAS Check what was tested 1 of 29 PFAS tested was detected in Kerrville’s record (PFPeA 3.2 ng/L). If PFAS matters to you, a filter certification names each compound it covers.
Look for NSF/ANSI 53 or 58, with each compound you care about named on the listing
PFAS in Kerrville →
Your path: My water tastes of chlorine The disinfectant is not in this record 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.
Look for NSF/ANSI 42 (chlorine taste and odor)
Water treatment technologies →
Your path: I have scale or hard water Hardness is not in this record Your utility’s annual water quality report usually lists hardness; a test strip also measures it.
Look for Softener: NSF/ANSI 44 (softeners)
Hard water explained →
Your path: I want the broadest reduction Reverse osmosis at one tap Reverse osmosis reduces many dissolved contaminants, including lead and minerals, at a single faucet, with some water sent to drain.
Look for NSF/ANSI 58

For Kerrville, PFPeA 3.2 ng/L was detected, with no federal or state limit; the lead 90th-percentile result was 3.34 µg/L against the 15 µg/L action level. CITY OF KERRVILLE (PWSID TX1330001) has a Purity Score of 86/100 (confidence: moderate), assessed at the water-system level and computed only from contaminants that were measured.

Methodology: how we analyze water . Prepared with AI assistance and reviewed by the PurityMap Editorial Team before publication.
Methodology
How PurityMap reads Kerrville’s water 01 Source data EPA SDWIS, EPA UCMR 5 and utility reports, each dated and linked.
02 Normalize Units converted to one basis; a non-detect kept distinct from zero.
03 Classify Each result tagged by reference type: MCL, action level, screening level or aesthetic.
04 Compare to the named reference Every value sits against its own reference, never a blended one.
05 Score Measured subjects summarised at the water-system level; an open health-based violation caps the score.
06 Match 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. CITY OF KERRVILLE · PWSID TX1330001 · Purity Score 86/100 (Good) · Confidence: moderate · Assessed at the water-system level
