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.
Research and editorial responsibility
Zero Trace Water Research Team
The team reviews public-water-system identities, PWSIDs, utility reports, state and federal records, ZIP-level research links and treatment claims for KentuckyWaterFiltration.com.
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.
Evergreen review cadence
Methodology and editorial-policy pages use an 18–24 month routine review window.
Earlier review occurs when a material error, major regulatory change, public-water-system change or business-process change affects the guidance. City pages keep separate reviewed dates because providers, PWSIDs, reports and links can change independently.
