Editorial standards

• Facts come from official sources (EPA, NH DES, CDC, NSF) and every page lists its sources.
• We separate detections, action level exceedances and violations, and never call water safe or unsafe.
• Pages show when the data was published and imported.
• We do not accept payment to change any record or wording.
• Affiliate links, when present, are labeled and never change what a page says about a water system.
• Errors are fixed and the page date is updated. Report a correction.

TapWaterPro is independent and not affiliated with the EPA, NH DES or any water system.
