Reading a Consumer Confidence Report with Confidence

How to Make Sense of Water Quality Reports from your Local Water Utility

It’s undeniable that knowing what’s in your water is, at the very least, prudent. At SimpleWater, we think it’s crucial. What you put in your body impacts both your short-term and long-term health. Our goal is to enable people to both discover and understand what is in their drinking water. Our Tap Score home water testing kits are one means of spreading that goal, but there are lot of other resources out there that that can shed some light about what flows from your tap. If you are wondering why your tap water, smellslooks, or even tastes funny–a Consumer Confidence Report (CCR) is one way to start finding answers.

What is a Consumer Confidence Report?

Simply put, a CCR is a water quality report. According to the U.S. Environmental Protection Agency(EPA) the purpose of these reports are to improve public health protection and provide information to enable water consumers to make educated decisions regarding potential health risk pertaining to the following:

  • Drinking water quality
  • Drinking water treatment
  • Drinking water supply management

You will only receive a CCR if you are on a community water system. People who receive their water from a private well do not receive CCRs, as private wells are not regulated by the EPA. However, if you are on a private groundwater well and would like more information–we recommend taking a look at the Center For Disease Control’s Private Ground Water Wells page.  

How Can I Receive My Consumer Confidence Report?

The way you are able to access your CCR depends on your living situation.

  • If you live in a home: You will most likely automatically receive a copy of your CCR from your local water utility via mail each year.
  • If you live in a condominium or apartment: You may not receive a direct copy of their CCR. However, you can still access your water quality reports by calling your local water provider or looking up  your community water system’s website. If your community water system does not have a website, search your area on the Safe Drinking Water Information System (SDWIS) and try calling them or your local water district

What Does a Consumer Confidence Report Tell You?

At first glance, CCRs can appear quite technical. However, once you know what to look for,  you will find a wealth of valuable information. All Consumer Confidence Reports are required to contain certain elements, such as information regarding:

All data on your CCR will be tailored to your local water utility.

What Does All of This Mean?!

To read the CCR above, you can interpret each column as telling you:

Column 1:  What contaminant they evaluated (e.g. Barium)

Column 2: The contaminant Maximum Contaminant Level (MCL) and Maximum Contaminant Level Goals

Column 3: The average concentration of that contaminant that was detected in your water in the water test

Column 4: The range of concentrations of the contaminant that was detected in your water (they take multiple samples)

Column 5: Whether or not the concentration in your water violates the MCL

Column 6: Explanation of where the contaminant comes from naturally

Column 7: A short overview of health effects related to the contaminant.
