Find the report
Search your city plus "drinking water report" or check the utility website. Numbers are system averages — your street can still differ slightly.
What to note
- Disinfectant type (chlorine vs chloramine)
- Any lead/copper sample notes for older plumbing
- Hardness if published (sometimes only on request)
- Contaminants near guideline limits that motivate RO
Reports vs in-home reality
Building plumbing, softeners and private wells are outside the plant report. Homes on wells need their own lab tests.
Turn insight into a plan
Use the Water Problem Wizard with city water selected, or request a quote and paste report highlights into the notes field.
