Evidence-first next steps

Confirm the problem before choosing treatment

This profile can help you ask the right question. It cannot select equipment for a property without a current result from the serving utility or the tap.

Confirm the serving system

ZIP boundaries and utility service areas do not perfectly match. Verify the system on a water bill before relying on system-wide records.

Read the current utility report

An active health-based record is present. Follow the utility's current notice and public-health instructions.
