No citywide exposure assumptions
A utility result does not prove the same condition at every household, and a ZIP code does not establish the water supplier.
Editorial transparency
Research Team and Review Process
The Zero Trace Water Research Team organizes source review, provider identification, local water education and corrections for the Ohio regional site.
Who prepares the pages
Research attribution without invented credentials.
Pages are attributed to the Zero Trace Water Research Team. The site does not invent a named scientist, engineer, physician, laboratory director or licensed water professional who did not actually review the content.
Editorial work includes provider and PWSID research, utility-report linking, source-water context, ZIP limitations, structured-data review, cross-state linking and correction tracking.
Editorial safeguards
What the team will not claim without evidence
No unsupported treatment promises
Reduction claims must be tied to the complete model, contaminant, standard, capacity and maintenance conditions.
No invented local presence
The regional site does not fabricate offices, phone numbers, employees, licenses, ratings or reviews.
No hidden corrections
Material corrections are documented through the corrections page and reflected in the page's reviewed date.
Review cadence
Evergreen policy pages, responsive city research
Methodology and editorial-policy pages use an 18–24 month routine review window. City pages, provider records and external links may need earlier updates when a utility changes reports, service relationships, PWSIDs, monitoring information or source links.
