Please note: This page is a plain-language overview and is not the official report. Values shown are the federal or state limits, not measured results — refer to your utility's published Consumer Confidence Report for current measured values. CCRs reflect the utility's system; conditions at your own tap can differ due to household plumbing. Book a free in-home test for tap-level data.

What an In-Home Test Adds to Your CCR
