Instructions for using the draft report

  1. Review the data for accuracy and completeness. If errors are discovered, please contact us.
  2. If your system used purchased water, ensure all applicable water quality data from the wholesale system(s) are included with the report.
  3. Update or complete the blank sections and/or tables of the report, especially:
    1. The potential sources of contamination column using the source water assessment summary.
    2. Highest compliance value (locational running annual average) for TTHM and HAA5.
    3. Detected results for UCMR3, cryptosporidium, and radon.
  4. Add information about any violations.

Frequently asked questions

  • We receive all of our water from another system. Do we have to produce and deliver our own CCR?
    • Your monitoring schedule, found on, identifies if this is required for your water system. Data from the system you purchase water from must also be included. To accomplish this, you may choose to attach their CCR to your own CCR with a cover letter explaining you purchase water from that system.
  • How do I use the CCR to meet a public notification requirement (for example: for a monitoring violation or a Fluoride secondary MCL)? 
    • Ensure that all 10 required elements for public notices are included in the CCR.  You may get a copy of the Public Notice 10 Required Elements from
  • ​Is electronic delivery an option to meet the “direct delivery” requirement?
    • ​Yes, but there are specific requirements water systems must meet. A guidance document has been created to address these requirements and is posted above.
  • I’m monitoring for Unregulated Contaminant Monitoring Rule (UCMR). What do I include?
    • Systems required to comply with UCMR must include detected contaminants. A table and statement are included in the draft reports for you to complete or use. If not conducting UCMR sampling then the table can be removed.
  • I had a backflow prevention or cross-connection treatment technique violation. What do I include?
    • ​You must include the following statement exactly as written: "We have an inadequate backflow prevention and cross-connection control program. Uncontrolled cross connections can lead to inadvertent contamination of the drinking water." If applicable, you must also include: "We have installed or permitted an uncontrolled cross-connection or we experienced a backflow contamination event.".
  • How do I report detected Cryptosporidium or Radon?
    • ​If the system’s monitoring indicates the presence of Cryptosporidium (in source water or finished water) or radon (in finished water only), the CCR must include the results and an explanation of the significance of the results.
    • Reporting Cryptosporidium: If the system has completed testing that indicates the presence of Cryptosporidium, either in its source water or its finished water:
      • Include a summary of the test results.  Each system may choose whether or not to report the actual analytical results as a part of this summary.
      • Include the following explanation of the significance of cryptosporidium in water test results:
        “Cryptosporidium is a microbial pathogen found in surface water throughout the United States.  Although filtration removes cryptosporidium, the most commonly used filtration methods cannot guarantee 100 percent removal.  Our monitoring indicates the presence of these organisms in our source water and/or finished water.  Current test methods do not allow us to determine if the organisms are dead or if they are capable of causing disease.  Ingestion of cryptosporidium may cause cryptosporidiosis, an abdominal infection.  Symptoms of infection include nausea, diarrhea, and abdominal cramps.  Most healthy individuals can overcome the disease within a few weeks.  However, immuno-compromised people are at greater risk of developing life-threatening illness.  We encourage immuno-compromised individuals to consult their doctor regarding appropriate precautions to take to avoid infection.  Cryptosporidium must be ingested to cause disease, and it may be spread through means other than drinking water.”
    • Reporting Radon: If the system has completed monitoring that indicates the presence of radon in its finished water:
      • ​Include the results of monitoring (the analytical values) reported by the lab.
      • Include the following explanation of the significance of radon in water test results:
        “Radon is a radioactive gas that you cannot see, taste, or smell.  It is found in the soil throughout the United States.  Radon can move up through the ground and into a home through cracks and holes in the foundation.  Radon can reach high levels in all types of homes.”  Radon can also be released from tap water from showering, washing dishes, and other household activities.  Compared to radon entering the home through the soil, radon entering the home through tap water will be, in most cases, a small source of radon in indoor air.”
        “Radon is a known human carcinogen.  Breathing air that contains radon can lead to lung cancer.  Drinking water that contains radon may also cause increased risk of stomach cancer.  If you are concerned about radon in your home, test the air in your home.  Testing is inexpensive and easy.  Fix your home if the level of radon in your air is four (4) picocuries per liter of air (pCi/L) or higher. There are simple ways to fix a radon problem that are relatively inexpensive.  For additional information, call the state radon program at 303-692-3030 or call the EPA Radon Hotline 1-800-SOS-RADON.”
  • What is the Consumer Confidence Report (CCR)?
    • The CCR is the centerpiece of the right-to-know provisions in the 1996 Amendments to the Safe Drinking Water Act. The CCR is an annual water quality report designed to assist your customers to make informed choices that affect their health and the health of their families.
  • When is the CCR deadline?
    • The CCR must be delivered to the system’s consumers by June 30th every year. A copy of the CCR and the Certificate of Delivery Form must also be submitted to us by June 30th every year. Check the appropriate box at the bottom of the Certificate of Delivery Form.
    • IMPORTANT NOTE: Even if you use the DRAFT CCR supplied by us, you must still submit a copy of the CCR and the Certificate of Delivery Form to us by the deadline.
  • We are a new community water system, do we need to produce and deliver a CCR?
    • Only community water systems that began operation before the start of the previous calendar year need to produce and deliver a CCR.  Your monitoring schedule, available at identifies if this is required for your water system.
  • ​How do I receive a small-system direct delivery mailing waiver?
    • The Certificate of Delivery Form describes the population criteria and consumer notification requirements of these waivers. Indicate this on the Certificate of Delivery Form by completing the correct section.
  • What if I do not have Microsoft Word?
    • There are a couple of free alternatives: 1) Open Office 2) Google Docs. Simply download your DRAFT CCR from our website and then open it using one of the two alternatives. Caution, the conversion might affect the document’s formatting. 
  • If there are errors in the data on the draft CCR, how do I get them corrected?
    • Data: Please note that some of the units of measurement have been converted in order to make the data more understandable to the water users in comparison to the MCL units (this is not an error). If you discover an error in our data, the water system is responsible for making corrections to the CCR prior to distribution. If you have a question about the data or a violation please contact your compliance specialist.
    • Water System Update Forms:  The water system is responsible for making corrections to the CCR. To have these errors corrected in the our database, complete and submit a system update form.
  • How do I complete the applicable blank Source Water Assessment Report (SWAP) Summary?
    • We have completed SWAP reports for all active community water systems on or before April 2001. Visit Source Water Assessment Reports by County. Every year, the CCR must contain a brief description of the SWAP assessment results including instructions on how the consumer can obtain their own copy. On the draft CCR, the water system needs to fill in a summary of potential sources of contamination (found on Table 2 and Table 3 of the SWAP report) in the space provided in the “Our Water Source(s)” section of the draft CCR. If your assessment results are not available online then identify what potential source(s) of contamination there might be. If you have questions about the SWAP report, please call the John Duggan at 303-692-3534.
