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 RICHARD L SEAL at 303-807-4743 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 naturallyoccurring 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 in Drinking Water
If present, elevated levels of lead can cause serious health problems 
(especially for pregnant women and young children). It is possible 
that lead levels at your home may be higher than other homes in the 
community as a result of materials used in your home’s plumbing. If 
you are concerned about lead in your water, you may wish to have 
your water tested. When your water has been sitting for several 
hours, you can minimize the potential for lead exposure by flushing 
your tap for 30 seconds to 2 minutes before using water for drinking 
or cooking. Additional information on lead in drinking water, testing 
methods, and steps you can take to minimize exposure is available 
from the Safe Drinking Water Hotline (1-800-426-4791) or 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 159060, HEENEY WATER DISTRICT, or by 
contacting RICHARD L SEAL at 303-807-4743. 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.HEENEY WATER DISTRICT, PWS ID: CO0159060 2021 CCR Page 2 of 3
Our Water Sources
Sources (Water Type - Source Type) Potential Source(s) of Contamination
HEENEY SPRING (Groundwater-Spring) Deciduous Forest, Evergreen Forest
Terms and Abbreviations  Maximum Contaminant Level (MCL) − The highest level of a contaminant allowed in drinking water.  Treatment Technique (TT) − A required process intended to reduce the level of a contaminant in drinking water.  Health-Based − A violation of either a MCL or TT.  Non-Health-Based − A violation that is not a MCL or TT.  Action Level (AL) − The concentration of a contaminant which, if exceeded, triggers treatment and other regulatory 
requirements.  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 90th Percentile, 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
HEENEY WATER DISTRICT 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, 2020 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. HEENEY WATER DISTRICT, PWS ID: CO0159060 2021 CCR Page 3 of 3
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.
