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.
General
Information About Drinking Water
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. Some people may be more vulnerable
to contaminants in drinking water than the general population. Immuno-compromised 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, such as viruses and bacteria that may come from sewage
treatment plants, septic systems, agricultural livestock operations, and
wildlife.
·
Inorganic
contaminants, such as salts and metals, which can be
naturally-occurring or result from urban stormwater runoff, industrial or
domestic wastewater discharges, oil and gas production, mining, or farming.
·
Pesticides
and herbicides that may come from a variety of sources, such as
agriculture, urban stormwater runoff, and residential uses.
·
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 stormwater runoff, and septic systems.
·
Radioactive
contaminants, that can be naturally occurring or be the result of
oil and gas production and mining activities.
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.
Our
Water Source(s)
The system’s
sources of water are listed below.
Well No. 18 Ground Water
If we used purchased
water, this report is required to include water quality data for the purchased
water with this report.
The Colorado
Department of Public Health and Environment has provided us with a Source Water
Assessment Report for our water supply.
You may obtain a copy of the report by visiting www.cdphe.state.co.us/wq/sw/swaphom.html
or by contacting Scott E. Johnson,
District Manager at
(719) 256-4310 Ext.
12.
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.

to learn
more about what you can do to help protect your drinking water sources, any questions about the annual 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
To help you understand the terms and abbreviations
used in this report, we have provided the following definitions:
·
Parts per
million (ppm) or Milligrams per liter (mg/L) - one part per million corresponds to one minute in two years or a
single penny in $10,000.
·
Parts per
billion (ppb) or Micrograms per liter (µg/L)- one part per billion corresponds to one minute in
2,000 years, or a single penny in $10,000,000.
·
Parts per
trillion (ppt) or Nanograms per liter (nanograms/L) - one part per trillion corresponds to one minute in
2,000,000 years, or a single penny in $10,000,000,000.
·
Parts per
quadrillion (ppq) or Picograms per liter (picograms/L) - one part per quadrillion corresponds to one minute in
2,000,000,000 years or one penny in $10,000,000,000,000.
·
Picocuries
per liter (pCi/L) -
picocuries per liter is a measure of the radioactivity in water.
·
Nephelometric
Turbidity Unit (NTU) - nephelometric
turbidity unit is a measure of the clarity of water. Turbidity in excess of 5
NTU is just noticeable to the average person.
·
Action Level (
·
Action Level
Goal (ALG) - The
“Goal” is the level of a contaminant in drinking water below which there is no
known or expected risk to health. The
ALG allows for a margin of safety.
·
Treatment
Technique (TT) - A
treatment technique is a required process intended to reduce the level of a
contaminant in drinking water.
·
Maximum
Contaminant Level Goal (MCLG) - The
“Goal” is 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
Contaminant Level (MCL)- The
“Maximum Allowed” is the highest level of a contaminant that is allowed in
drinking water. MCLs are set as close to
the MCLGs as feasible using the best available treatment technology.
· 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.
· 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.
· Running Annual Average (RAA): An average of monitoring results for the previous 12 calendar months.

Health
Effects Information About the Above Tables
Nitrate in drinking water at levels above 10 ppm is a health
risk for infants of less than six months of age. High nitrate levels in drinking water can
cause blue baby syndrome. Nitrate levels
may rise quickly for short periods-of-time because of rainfall or agricultural
activity. If you are caring for an
infant, and detected nitrate levels are above 5 ppm, you should ask advice from
your health care provider.
If arsenic is less
than the MCL, your drinking water meets EPA’s standards. EPA’s standard balances the current
understanding of arsenic’s possible health effects against the costs of
removing arsenic from drinking water.
EPA continues to research the health effects of low levels of arsenic,
which is a mineral known to cause cancer in humans at high concentrations and
is linked to other health effects such as skin damage and circulatory problems.
Infants and young children
are typically more vulnerable to lead in drinking water than the general
population. It is possible that lead
levels at your home may be higher than at other homes in the community as a
result of materials used in your home’s plumbing. If you are concerned about elevated lead
levels in your home’s water, you may wish to have your water tested. Flush your tap for 30 seconds to 2 minutes
before using tap water. Additional
information is available from the EPA Safe Drinking Water Hotline at
1-800-426-4791.
