Consumer Confidence Reports

What is a Consumer Confidence Report (CCR)?

The 1996 Safe Drinking Water Act Amendments require all community water systems to report annually to their customers regarding the quality of their drinking water and any risks associated with contaminants detected in the water.  Water systems must report  data for the previous calendar year by July 1 of each year.

What Information Does a CCR Contain?

Water systems may include any appropriate information to enhance their reports, however the reports must contain the following information:

  • the lake, river, aquifer, or other source of the drinking water;
  • a brief summary of the susceptibility to contamination of the local drinking water source, based on the source water assessments that states are completing over the next five years;
  • how to get a copy of the water system's complete source water assessment; 
  • the level (or range of levels) of any contaminant found in local drinking water, as well as EPA's health-based standard (maximum contaminant level) for comparison;
  • the likely source of that contaminant in the local drinking water supply;
  • the potential health effects of any contaminant detected in violation of an EPA health standard, and an accounting of the system's actions to restore safe drinking water; 
  • the water system's compliance with other drinking water-related rules;
  • an educational statement for vulnerable populations about avoiding Cryptosporidium;
  • educational information on nitrate, arsenic, or lead in areas where these contaminants are detected above 50% of EPA's standard; and
  • phone numbers of additional sources of information, including the water system and EPA's Safe Drinking Water Hotline (800-426-4791).

In addition, some water systems may include public notifications for violations of monitoring or other requirements.

How Do I Obtain a Copy of My Water System's CCR?

Most water systems mail the reports to their customers before the July 1 deadline each year, however systems may deliver their reports through newspaper advertisements or other means.  Some systems make their reports available on their internet websites.  Website links for some larger systems are available below.  If your water system is not listed, please contact the system directly for a copy of the report.


If you have additional questions, please contact the Water Supply Program at or 410-537-3729, or call EPA's Safe Drinking Water Act Hotline at 1(800)426-4791.
