Field notes
The homepage says coverage spans 1,500 state, county, and utility pages, while its aggregate covers 8,990 community water systems with complete EPA PFAS test sets.

Its filter guide discusses filter types and certifications, while warning that certification is not proof of reaching 4 ppt.
