Clean water is a right,
not a luxury
We help people understand the water they drink — through honest research, plain-language guides, and zero industry strings attached.
Water Sommelier is an independent publication dedicated to one question: is the water coming out of your tap safe to drink, and how do you actually know?
We translate primary research, regulatory filings, and lab data into plain guides anyone can act on. No fearmongering, no filter-affiliate hype — just the science of what's in your water and the practical steps that move the needle.
Our work covers municipal water quality, well water, at-home testing protocols, contaminant chemistry, and filter performance. Everything is fact-checked against current EPA and WHO standards.
Our mission
Make drinking water transparency accessible to everyone — not just chemists and regulators.
Independent
We never accept payment to recommend a filter, kit, or treatment product. Ever.
Reader-funded
Subscriptions and the Water Sommelier app keep our reporting free of conflicts.
