The three questions that decide everything
Almost every home-water decision comes down to three questions, in order:
1. What's in my water?
Public water users start with the CCR; well owners start with a lab test. You can't choose treatment until you know the problem.
2. What problem am I solving?
Taste and odor, hard-water scale, a specific contaminant, or peace of mind for drinking water — each points to a different solution.
3. Which system fits?
Point-of-use (one tap) vs. point-of-entry (whole house), and how to size and maintain whatever you choose. Our selector answers this in about a minute.
Why this site exists
Plain-English water guidance, without the fear tactics
Most people have never read their water quality report and aren't sure whether the filter pitcher, the softener the last owner left behind, or the system a salesperson pitched actually does anything for their water. Home Water Guide exists to close that gap.
We're an independent educational resource — not a government agency, not a utility, and not a filter company. What we do is translate the official rules, reports, and testing standards into checklists and guides you can actually use. We keep three commitments on every page:
- We link to official sources (EPA, state water agencies, NSF/WQA certification bodies) for anything regulatory or safety-related
- We avoid fear-based language — water topics get treated as practical problems with practical next steps
- We never fabricate local water-quality numbers; local report pages point you to the official data for your exact system
Local water reports
Covering California, Texas, Florida, Arizona, Colorado, Washington, Oregon, Nevada, Utah, Idaho, New Mexico, Montana, and Wyoming
Our local report guides help you find and understand the water quality data for your specific city and water system, showing each system's official EPA record and linking to the official state lookup tools — no invented numbers.
FAQ
Frequently asked questions
Is Home Water Guide a government agency?
No. Home Water Guide is an independent educational resource. We are not affiliated with or endorsed by the EPA, any state water agency, any water utility, or any laboratory. Our guides link to official sources so you can verify anything regulatory or safety-related directly.
How do I find my local water quality report?
If you're on public water, your utility publishes an annual Consumer Confidence Report (CCR). Start with our guide on how to find your water report, or use the state pages for California, Texas, Florida, Arizona, Colorado, Washington, Oregon, Nevada, Utah, Idaho, New Mexico, Montana, and Wyoming, which link to the official state lookup tools.
Which water treatment system do I actually need?
It depends on what's in your water and what problem you're solving. Reverse osmosis targets drinking-water quality at one tap, water softeners address hardness, and whole-house filters treat everything entering the home. Our treatment comparison walks through how to match the system to the problem.
Do you sell filters or testing?
No. Home Water Guide is educational and does not sell equipment or lab tests. We also don't refer you to contractors or take referral fees, and we collect no personal information — there is no form on this site. Everything here is free to read.
This is a guide, not an authority. Home Water Guide is an independent educational resource. We are not a government agency, a water utility, or a laboratory, and we are not affiliated with or endorsed by any of them. Nothing here is medical, legal, engineering, or regulatory advice.
Always verify with the official source. Drinking-water rules, limits, and product certifications change, and published data can lag reality by months. Before you rely on anything on this page — especially for a health decision, a purchase, or a dispute — confirm it with the EPA, your state drinking-water agency, your utility, or a certified laboratory. Where we cite a figure, we link the official record it came from so you can check it yourself.
We do not sell water treatment equipment or laboratory testing, take referral or affiliate fees, or collect any personal information. We do not guarantee removal of any contaminant — only a product certified for a specific claim does that, and only within its stated limits.
