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
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 RICHARD L SEAL at 303-807-4743. 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 our system name or ID, 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.

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, 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.
