About
Hard Water Answers is a small independent guide that helps people match their actual water hardness to a sensible fix, or to no fix at all.
How we write
- Every factual claim links to a primary or authoritative source: EPA, USGS, NSF, or the utility's own report.
- We don't invent statistics, and we don't publish product reviews or rankings based on testing we haven't done.
- Every page has a last-updated date. Utility data is cited with its report year.
- This is general information, not plumbing, medical or professional advice.
