Our standards
- We explain published public-health data; we don't run tests or give medical advice.
- Every factual claim links to a primary source, usually EPA or a state agency.
- We don't publish estimates of our own.
- Commercial links never change what a page says. We don't accept payment for coverage, and we don't recommend or rank contractors.
Corrections
If something is wrong or out of date, tell us. We review every report, fix confirmed errors, and update the page's source-check date.
