Consumer Confidence Reports: What Your Customers Actually Want to Know

Every community water system serving more than 25 people is required to produce an annual Consumer Confidence Report: the CCR: and deliver it to customers by July 1st each year. For most small systems, writing the CCR is a task that gets done in a hurry sometime in June.

That's understandable. You're running a water system. But the CCR is worth treating as more than a compliance checkbox, because customers who understand their water supply are more likely to trust you when something does go wrong.

What the Rule Actually Requires

EPA's Consumer Confidence Report rule (40 CFR Part 141, Subpart O) requires community water systems to include:

• Information about your water source
• A list of all detected contaminants and their levels
• The applicable MCL and MCLG for each detected contaminant
• Any violations that occurred during the reporting period
• Health effects language for any contaminant that exceeded an MCL
• Educational language on nitrates and arsenic if your system serves pregnant women or infants

Systems serving fewer than 10,000 people can deliver the CCR by mail, hand delivery, posting in a public place, or: if approved by the state: electronic delivery.

The Table Is Not Enough

The required contaminant table tends to dominate most small system CCRs. It needs to be there and it needs to be accurate. But customers rarely understand what they're looking at. TTHM, HAA5, turbidity NTU: this language means something to you and nothing to the person reading it at their kitchen table.

Add a short paragraph above the table that translates it in plain language. Something like: "The table below lists every substance we tested for in your water last year. When a result appears, it means we detected that substance: not that it poses a health risk. All results in this report were below the legal limits set by EPA."

That one paragraph will answer the first question most customers have before they even read the table.

Tell the Story of Your Source

Customers are curious about where their water comes from. A sentence or two about your source: a description of the aquifer, the watershed, or the spring: makes the report feel like it was written by a real person rather than assembled from a template. It also creates an opening to explain source protection and what the system does to keep the water clean before it reaches treatment.

Violations Require Plain Language

If you had a violation during the reporting year, it must appear in the CCR. Don't bury it in technical language. State what happened, what you did about it, and what you're doing to prevent it from happening again. A customer who reads a clearly explained violation that was resolved quickly is not going to lose confidence in their water system. A customer who feels like information was obscured or minimized will.

Keep a Copy

Maintain a copy of each year's CCR and your delivery certification records. State primacy agencies audit CCR compliance. If you can't demonstrate that your report was delivered on time, it's a violation even if the report itself was accurate.
