Read the fine print
What a water report won't tell you
When you pull your system's Consumer Confidence Report, a few things people ask about are not in it and should be confirmed directly:
- Your tap specifically. A system-wide report can meet every standard while an individual older home has an elevated lead result — lead usually comes from the service line or home plumbing, not the system. Use a certified tap test to be sure.
- Water hardness and taste/odor/staining are often not standardized in the report; ask your utility or use a home test. See our hard-water guide.
- Private wells get no report at all — test through an ELAP-approved lab. See our well testing guide.
