What is a Consumer Confidence Report (CCR)?

The Colorado Department of Public Health and Environment describes the CCR as follows:

"The CCR is a written document designed to be easily readable and understandable by water customers. The report contains:

  1. Information about your source water and a summary of the state source water assessment
  2. The name and phone number of a system contact person
  3. Information telling customers how they may participate in your system’s public meetings
  4. A table reporting the levels of detected contaminants with their maximum contaminant level (MCL), maximum contaminant level goal (MCLG), maximum residual level (MRDL), maximum residual level goal (MRDLG), action level (AL) or treatment technique (TT), common sources and the date the sample was taken
  5. Details of any violations of the drinking water regulations
  6. A list of any variances or exemptions issued by the State to the system
  7. Required informational and warning language
  8. Other educational material

Most reports will fit on a few sheets of paper.

The CCR summarizes information that the water system collects to comply with existing regulations. It is not necessary to engage in any new monitoring just for the CCR."

More Information on Water Monitoring

All drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that the water poses a health risk. Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised people, like those with cancer undergoing chemotherapy, those who have undergone organ transplants, people with HIV-AIDS or other immune system disorders, some elderly, and infants, can be particularly at risk of infections. These people should seek advice about drinking water from their health care providers. For more information about contaminants and potential health effects, or to receive a copy of the U.S. Environmental Protection Agency (EPA) and the U.S. Centers for Disease Control (CDC) guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and microbiological contaminants call the EPA Safe Drinking Water Hotline at 1-800-426-4791.

The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally occurring minerals and, in some cases, radioactive material, and can pick up residual substances from the presence of animals or from human activity on the earth's surface. Contaminants that may be present in source water include:

  • Microbial contaminants, such as viruses and bacteria that may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife.
  • Inorganic contaminants, such as salts and metals, which can be naturally-occurring or result from urban storm water runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming.
  • Pesticides and herbicides that may come from a variety of sources, such as agriculture, urban storm water runoff, and residential uses.
  • Organic chemical contaminants, including synthetic and volatile organic chemicals, which are byproducts of industrial processes and petroleum production, and also may come from gas stations, urban storm water runoff, and septic systems.
  • Radioactive contaminants, that can be naturally occurring or be the result of oil and gas production and mining activities.

In order to ensure that tap water is safe to drink, the Colorado Department of Public Health and Environment prescribes regulations limiting the amount of certain contaminants in water provided by public water systems.
