Reach households while they're making decisions about their water.
TapWaterData turns fragmented government, utility and certification data into clear information about drinking-water quality, testing and treatment — and a weekly newsletter that lands while people are deciding whether to test, filter or treat. Commercial partners can support that work; they never influence it.
What readers are here to decide
Nobody subscribes to a drinking-water newsletter casually. People arrive with a question about their own tap and stay because the next question is already forming. These are the intents the site is built around — stated as topics, not as shares, because we do not collect the subscriber data that would make a percentage true.
Water-quality research
Someone has just looked up their own city or utility and read what was detected in it.
Water testing
Deciding whether a home test is warranted, which analytes to ask for, and which lab to use.
PFAS, lead and specific contaminants
Arriving with one named contaminant already in mind, usually from a news story or a utility notice.
Private well water
No utility report exists for them, so every answer has to come from their own testing and treatment.
Hard water
Scale, spotting and appliance damage — the problem people are most likely to spend money on first.
Filtration
Comparing pitcher, under-sink and reverse-osmosis options against a specific result they have in hand.
Whole-house treatment
Beyond what a point-of-use filter can fix: softeners, iron and sulfur removal, professional installs.
Leaks and monitoring
Households already instrumenting their plumbing, and the ones who just had a failure.
Home water decisions
New-home buyers and renovators settling their water setup while everything else is being chosen.
Buy the context, never the conclusion
Each sponsor sits beside a topic already on our editorial calendar. You can choose the relevant issue; you cannot choose what the reporting finds or recommends.

What the placement looks like
One block, in the body of the issue, labelled in words. It reads like the rest of the newsletter and is unmistakably paid — both on purpose.
SUPPORTED BY [BRAND] · PAID PARTNERSHIP
[60–90 words written by TapWaterData from sponsor-approved facts, claims and offer details. The sponsor checks factual accuracy; TapWaterData keeps final control of the reader experience.]
[One call to action →]
The format, fixed in advance
- 60–90 words drafted by TapWaterData after the sponsor supplies its approved facts, claims, offer and destination URL.
- A logo is optional — the block renders cleanly without one.
- Exactly 1 call to action. Two links in a short block stops being a partner note and starts being an ad.
- The call to action uses a branded Dub link to the partner’s own HTTPS destination with campaign parameters — never an affiliate link and never a subscriber identifier.
- A short post-send report is part of the package, not an upsell.
One commercial partner per newsletter issue.
There is a single paid position in each issue and it is never shared. That keeps the issue clean for the reader, puts the partner in front of the whole audience rather than a slice of its attention, and makes each week’s inventory genuinely finite — the calendar fills in order.

The platform behind the newsletter
Subscribers arrive through the data, not through a lead magnet. These figures are read from the live site every time this page is built.
- 18,737 cities with a published water-quality report
- 21,000+ public water systems
- 609 contaminants with a dedicated reference page
- Private-well guidance for the households a public water system never covers
- A filter certification checker that resolves NSF/ANSI and WQA claims against the certifiers' own listings
- Water-testing explainers that walk a reader from a symptom to the right test
- Hardness, treatment and filtration references written for people who are about to spend money
Evidence-first. Independent by design.
Where the analysis comes from
- Federal and state drinking-water data, plus the utilities’ own consumer confidence reports, are the basis of every city and system page.
- Product certification claims are checked against the certification bodies’ own listings rather than against a manufacturer’s marketing page.
- Coverage of our CCR standards analysis appeared in Water Online: Beyond Compliance: The Utilities Setting A New CCR Standard.
TapWaterData is independent and not affiliated with NSF International, IAPMO, or WQA.
What sponsorship does not buy
- Sponsors cannot pay for a ranking, a score, or a place in any recommendation.
- Sponsors cannot change an editorial conclusion, a test reading, or a data point.
- Sponsorship does not affect which products we recommend, on this site or in the newsletter.
- A sponsor cannot stop us covering, testing or recommending a competitor.
The terms that are not negotiable
These are a summary. The full sponsorship integrity policy is the version that governs every campaign.
- Commercial independence
- Sponsorship does not influence water-quality data, analysis, filter rankings, testing recommendations, certification findings, or any editorial conclusion.
- Competitive coverage continues
- A sponsor cannot prevent us from covering, testing, or recommending a competitor while their campaign is running.
- Exclusivity is only the paid position
- Commercial exclusivity applies only to the paid sponsor position in an issue: it never extends to editorial coverage, rankings, testing results or recommendations, and it can never be used to keep a competitor out of anything we publish.
- Subscriber privacy
- Sponsors never receive email lists, subscriber identities, addresses, or behavioural profiles. Reporting is aggregate campaign performance only.
