Report a Concern

Seen a DWLCA seal on a report from a lab that isn't in the registry? Had a result that doesn't add up? Know something about how samples are being handled? Tell us. Every submission is read by a person.

About the laboratory
About you (optional, but helps us follow up)

Your identity is not shared with the laboratory unless you tell us it's okay. Anonymous reports are accepted but harder to investigate.

What happens next

Acknowledged

Within 2 business days, if you gave us contact details.

Reviewed

The Certification Committee decides whether the concern is credible and in scope.

Investigated

Credible data-quality concerns trigger an unscheduled audit. Seal misuse gets a cease-and-desist and public notice.

Not for emergencies. If you believe water is unsafe to drink right now, stop drinking it and contact your local health department.
