We are pleased to present to you this year’s water quality report.  Our constant goal is to provide you with a safe and dependable supply of drinking water.  Please contact 
DAVID N JELINEK at 970-349-0885 with any questions or for public participation opportunities that may affect water quality.     

                                                                     General Information 
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.  More information about contaminants and potential health effects can be obtained by calling the Environmental Protection 
Agency’s Safe Drinking Water Hotline (1-800-426-4791) or by visiting epa.gov/ground-water-and-drinking-water. 
 
Some people may be more vulnerable to contaminants in drinking water than the general population.  Immunocompromised persons such as persons with cancer undergoing 
chemotherapy, persons 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 substances resulting from the presence of animals or 
from human activity. Contaminants that may be present in source water include: 
 • Microbial contaminants: viruses and bacteria that may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife. 
 • Inorganic contaminants: 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: may come from a variety of sources, such as agriculture, urban storm water runoff, and residential uses. 
 • Radioactive contaminants: can be naturally occurring or be the result of oil and gas production and mining activities. 
 • 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. 
 
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.  The Food and Drug Administration regulations establish limits for contaminants in bottled water that must provide the same 
protection for public health.

Lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and components associated with 
service lines and home plumbing. We are responsible for providing high quality drinking water and removing lead pipes, but cannot control the variety of materials used in 
plumbing components in your home. You share the responsibility for protecting yourself and your family from the lead in your home plumbing. You can take responsibility by 
identifying and removing lead materials within your home plumbing and taking steps to reduce your family's risk. Before drinking tap water, flush your pipes for several minutes 
by running your tap, taking a shower, doing laundry or a load of dishes. You can also use a filter certified by an American National Standards Institute accredited certifier to 
reduce lead in drinking water. If you are concerned about lead in your water and wish to have your water tested, contact DAVID N JELINEK at 970-349-0885. Information on 
lead in drinking water, testing methods, and steps you can take to minimize exposure is available at epa.gov/safewater/lead. 
 
                                                       Source Water Assessment and Protection (SWAP)  
The Colorado Department of Public Health and Environment may have provided us with a Source Water Assessment Report for our water supply. For general information or to 
obtain a copy of the report please visit wqcdcompliance.com/ccr. The report is located under “Guidance: Source Water Assessment Reports”.  Search the table using system 
name or ID, or by contacting DAVID N JELINEK at 970-349-0885.  The Source Water Assessment Report provides a screening-level evaluation of potential contamination that 
could occur. It does not mean that the contamination has or will occur. We can use this information to evaluate the need to improve our current water treatment capabilities and 
prepare for future contamination threats. This can help us ensure that quality finished water is delivered to your homes. In addition, the source water assessment results provide a 
starting point for developing a source water protection plan.  Potential sources of contamination in our source water area are listed on the next page. 
 
Please contact us to learn more about what you can do to help protect your drinking water sources, any questions about the Drinking Water Quality Report, to learn more about 
our system, or to attend scheduled public meetings. We want you, our valued customers, to be informed about the services we provide and the quality water we deliver to you 
every day.

Maximum Residual Disinfectant Level (MRDL) − The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a 
        disinfectant is necessary for control of microbial contaminants. 
 •      Maximum Contaminant Level Goal (MCLG) − The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow 
        for a margin of safety. 
 •      Maximum Residual Disinfectant Level Goal (MRDLG)              − The level of a drinking water disinfectant, below which there is no known or expected risk to health. 
        MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contaminants. 
 •      Violation (No Abbreviation) − Failure to meet a Colorado Primary Drinking Water Regulation. 
 •      Formal Enforcement Action (No Abbreviation) − Escalated action taken by the State (due to the risk to public health, or number or severity of violations) to bring a 
        non-compliant water system back into compliance. 
 •      Variance and Exemptions (V/E) − Department permission not to meet a MCL or treatment technique under certain conditions. 
 •      Gross Alpha (No Abbreviation) − Gross alpha particle activity compliance value. It includes radium-226, but excludes radon 222, and uranium. 
 •      Picocuries per liter (pCi/L) − Measure of the radioactivity in water. 
 •      Nephelometric Turbidity Unit (NTU) − Measure of the clarity or cloudiness of water. Turbidity in excess of 5 NTU is just noticeable to the typical person. 
 •      Compliance Value (No Abbreviation) – Single or calculated value used to determine if regulatory contaminant level (e.g.  MCL) is met. Examples of calculated values 
        are the 90 thPercentile, Running Annual Average (RAA) and Locational Running Annual Average (LRAA). 
 •      Average (x-bar) − Typical value.  
 •      Range (R) − Lowest value to the highest value. 
 •      Sample Size (n) − Number or count of values (i.e. number of water samples collected). 
 •      Parts per million = Milligrams per liter (ppm = mg/L)  − One part per million corresponds to one minute in two years or a single penny in $10,000. 
 •      Parts per billion = Micrograms per liter (ppb = ug/L)  − One part per billion corresponds to one minute in 2,000 years, or a single penny in $10,000,000. 
 •      Not Applicable (N/A)      – Does not apply or not available. 
 •      Level 1 Assessment – A study of the water system to identify potential problems and determine (if possible) why total coliform bacteria have been found in our water system. 
 •      Level 2 Assessment – A very detailed study of the water system to identify potential problems and determine (if possible) why an E. coli MCL violation has occurred and/or 
        why total coliform bacteria have been found in our water system on multiple occasions. 
                                                                                                                                                                                                              
                                                                         Detected Contaminants 

CRESTED BUTTE TOWN OF routinely monitors for contaminants in your drinking water according to Federal and State laws. The following table(s) show all detections found 
in the period of January 1 to December 31, 2022 unless otherwise noted. The State of Colorado requires us to monitor for certain contaminants less than once per year because 
the concentrations of these contaminants are not expected to vary significantly from year to year, or the system is not considered vulnerable to this type of contamination. 
Therefore, some of our data, though representative, may be more than one-year-old. Violations and Formal Enforcement Actions, if any, are reported in the next section of this 
report. 
 
Note: Only detected contaminants sampled within the last 5 years appear in this report. If no tables appear in this section, then no contaminants were detected in the last round of 
monitoring.

We are required to monitor your drinking water for specific contaminants on a regular basis. Results of regular monitoring are an indicator of 
whether or not our drinking water meets health standards. During the inspection it was identified that we did not complete all monitoring/testing, 
were not monitoring correctly, or were monitoring at an inappropriate location. Therefore, we cannot be sure of the drinking water quality during 
that time. 

What does this mean? What should I do? 

 ○ There is nothing you need to do at this time.If a situation arises where the water is no longer safe to drink, you will be notified within 24 
   hours.
