Move from index to evidence

  1. 1. Open your ZIP. Check distance, dates, confidence, and the associated utility.

Questions people ask

About water in Westboro

Is the water hard?

The indexed city median is 275 PPM. Open the ZIP report to verify the distance and confidence behind that estimate.

Is the tap water safe?

Compliance history is utility-wide and cannot guarantee conditions at every tap. Check current notices and test when address-specific evidence is needed.

Do I need treatment?

Choose treatment only after confirming the problem at the property. A softener targets hardness; contaminant treatment requires a matching, verified performance claim.
