•How You Can Help
We are pleased to present to you this years Annual
Drinking Water Quality Report. This report is designed to
inform you about the quality of the water and services we
deliver to you every day. Our constant goal is to provide
you with a safe and dependable supply of drinking water.
We want you to understand the efforts we make to
continually improve the water treatment process and
protect our water resources.
We are committed to ensuring the quality of your water.
Our water sources have been determined to be from
groundwater and surface water. Our water sources are
Rest Stop Well, Hi-Ute Well, Jeremy Ranch Well #4,
White Pine Well, Church Well, Storage Well, Old F-7 Well,
U224 Well, Upper Spring Creek Spring, New F-7 Well,
and Hi-Ute Well Repl-1. We also purchase water from
Mountain Regional SSD (#22137) and Park City Water
System
(#22011).
Lead
If present, elevated levels of 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. Summit Water is responsible for providing high
quality drinking water but cannot control the variety of
materials used in plumbing components. 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. If you are concerned about lead in your water,
you may wish to have your water tested. Information on
lead in drinking water, testing methods, and steps you can
take to minimize exposure is available from the Safe
Drinking Water Hotline or at www.epa.gov/safewater/lead.
ArsenicWhile your drinking water meets EPA's standard for
arsenic, it does contain low levels of arsenic. 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.
NitrateNitrate 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, you should
ask advice from your health care provider.
Total ColiformThe Total Coliform Rule requires water systems to meet a
stricter limit for coliform bacteria. Coliform bacteria are usually
harmless, but their presence in water can be an indication of
disease-causing bacteria. When coliform bacteria are found,
special follow-up tests are done to determine if harmful bacteria
are present in the water supply. If this limit is exceeded, the
water supplier must notify the public by newspaper, television or
radio. To comply with the stricter regulation, we have increased
the average amount of chlorine in the distribution system.
Cross Connection
There are many connections to our water distribution system.
When connections are properly installed and maintained, the
concerns are very minimal. However, unapproved, and
improper piping changes or connections can adversely affect
not only the availability, but also the quality of the water. A
cross connection may let polluted water or even chemicals
mingle into the water supply system when not properly
protected. This not only compromises the water quality but can
also affect your health. So, what can you do? State law
requires irrigation and fire suppression systems to be equipped
with backflow prevention devices. These devices are required
to be tested annually by a certified backflow tester. Do not
make or allow improper connections at your home. Even that
unprotected garden hose lying in the puddle next to the
driveway is a cross connection. The unprotected lawn sprinkler
system after you have fertilized or sprayed is also a cross
connection. When the cross connection is allowed to exist at
your home, it will affect you and your family first. If you’d like
to learn more about helping to protect the quality of our water,
call us for further information about ways you can help.
Source Protection
The Drinking Water Source Protection Plan for Summit Water is
available for your review. It contains information about source
protection zones, potential contamination sources and
management strategies to protect our drinking water. Our
sources have been determined to have a low level of
susceptibility from potential contamination from sources. We
have also developed management strategies to further protect
our sources from contamination. Please contact us if you have
questions or concerns about our source protection plan.
Potential Health Risks
All sources of drinking water are subject to potential
contamination by constituents that are naturally occurring or
man-made. Those constituents can be microbes, organic or
inorganic chemicals, or radioactive materials. 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 at 1-800-426-4791.
MCLs
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
from infections. These people should seek advice from their
health care providers about drinking water. EPA/CDC
guidelines on appropriate means to lessen the risk of infection
by cryptosporidium and other microbiological contaminants are
available from the Safe Drinking Water Hotline [phone]).
MCLs are set at very stringent levels. To understand the
possible health effects described for many regulated
constituents, a person would have to drink 2 liters of water
every day at the MCL level for a lifetime to have a one-in-a-
million chance of having the described health effect.
Customer Service
Summit Water Distribution Company employees are

Table Definitions:
In the test reults table you will find many terms and abbreviations you might not be familiar with. To help you better understand these terms we’ve provided the following definitions:Non-Detects (ND) - laboratory analysis indicates that the constituent is not present.ND/Low - High - For water systems that have multiple sources of water, the Utah Division of Drinking Water has given water systems the option of listing the test results of the constituents in one table, instead of multiple tables. To accomplish this, the lowest and highest values detected in the multiple sources are recorded in the same space in the report table. 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 (ug/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.Millirems per year (mrem/yr) - measure of radiation absorbed by the body.Million Fibers per Liter (MFL) - million fibers per liter is a measure of the presence of asbestos fibers that are longer than 10 micrometers.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 (AL) - the concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.Treatment Technique (TT) - A treatment technique is a required process intended to reduce the level of a contaminant in drinking water.Maximum Contaminant Level (MCL) - The “Maximum Allowed” (MCL) 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 Contaminant Level Goal (MCLG) - The“Goal”(MCLGthe 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(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 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.Date- Because of required sampling time frames i.e. yearly, 3 years, 4 years and 6 years, sampling dates may seem out-dated. Waivers (W)- Because some chemicals are not used or stored in areas around drinking water sources, some water systems have been given waivers that exempt them from having to take certain chemical samples, these waivers are also tied to Drinking Water Source Protection Plans.

Water Conservation:
Water conservation measures are an important first step in pro-
tecting our water supply. Such measures not only save the supply
of our source water, but you can also save money by reducing
your water bill. Here are a few suggestions:
Conservation in your home:
•Take shorter showers
•Run the dishwasher only when full
•Soak dishes before washing
•Fix leaking faucets, pipes, toilets, etc.
•Wash full loads of laundry
•Replace old fixtures
•Do not use the toilet for trash disposal
•Install water saving devices
Conserve Outdoors:
•Water the lawn and garden in the early morning or late eve-
ning
•Use mulch around plants and shrubs
•Repair leaks in faucets and hoses
•Use water-saving nozzles
•Use water from a bucket to wash your car and save the hose
for rinsing
