WaterAnswer.com exists because water quality information online is either too technical (regulatory documents and lab reports) or too commercial (filter company blogs that recommend the products they sell).
The gap this site fills: plain-language guidance, sourced from authoritative data, that tells you what’s actually in your water and what to do about it.
What We Cover
The site covers drinking water quality for homeowners and private well owners. That means:
- Contaminant profiles explaining what a contaminant is, where it comes from, what the EPA limit is, and what actually removes it
- Product reviews for filters, test kits, and treatment systems, with NSF certification requirements built into every recommendation
- How-to guides for testing, installation, and maintenance
- Reference articles on water regulations, certification standards, and how to read utility reports
We don’t cover bottled water brands, spa treatments, or anything where “water quality” is a marketing claim rather than a measurable fact.
How Content Is Researched
Every contaminant article is built from primary sources:
- EPA regulations and Maximum Contaminant Level tables
- CDC drinking water guidance
- USGS water quality research and contamination mapping
- Peer-reviewed studies, cited by title, year, and PMID where available
- NSF International’s certified product database for all filter claims
We don’t cite “experts say” without naming the expert. We don’t attribute a statistic to “research suggests” without linking the research. If a claim can’t be sourced, it doesn’t appear here.
