What to write to us about
- Corrections: a health limit changed, a state program moved, a link is broken. Please include the page URL and, if you can, the official source.
- State and local resources: know a health department, extension service or free-testing program we should list? Send us the link.
- Questions: we can’t interpret individual lab reports or give one-on-one advice, but common questions shape our guides.
- Brands and partnerships: we’re happy to hear from labs, test-kit makers and treatment companies. Sponsored placements are always labeled, and payment never changes a recommendation.
We aim to reply within a few business days.
We can’t give medical advice or interpret your results. If your water tested positive for E. coli or another urgent problem, stop drinking it, use bottled water, and contact your state or local health department now. For product support, contact the manufacturer directly.
