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 Mike
Billingsley at 970-349-7411
with any questions about the Drinking Water Consumer Confidence
Report or for public participation opportunities that may affect the
water quality.

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).
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.
•Radioactive contaminants, that
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.
|
|
|
|
|
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 http://www.epa.gov/safewater/lead.

Abbreviation
|
Definition
|
|
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.
|
|
Treatment Technique
|
TT
|
A treatment technique is a required process
intended to reduce the level of a contaminant in drinking water.
|
|
Action Level
|
AL
|
The concentration of a contaminant which, if
exceeded, triggers treatment or other requirements which a water
system must follow.
|
|
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.
|

The typical value. Mathematically it is the sum of
values divided by the number of samples.

compliance value. It includes
radium-226, but excludes radon 222 and uranium.
|
|
Microscopic Particulate Analysis

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 http://www.cdphe.state.co.us/wq/sw/swapreports/swapreports.html,
clicking on Gunnison
County and selecting 226712;
Skyland Md or by contacting Mike Billingsley at 970-349-7411. For general information about Source
Water Assessment please visit http://www.cdphe.state.co.us/wq/sw/swaphom.html.
Potential sources of contamination in our source water area come
from:
Natural Occurances and Domestic Dischharges.
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.
Please contact Mike
Billingsley at 970-349-7411
to learn more about what you can do to help protect your drinking
water sources, any questions about the Drinking Water Consumer
Confidence 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.

Skyland Md 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, 2010 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. Any
additional information may be found in the final 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, that means that Skyland Md did
not detect any contaminants in the last round of monitoring.
