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 ftom
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).
Nitrate
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. lf you are caring for an infant, you should
ask advice from your health care provider.
Total Coliform
The 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. lf 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.

Source Protection
The Drinking Water Source Protection Plan for Summit Water is
available for your review. lt 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 occuning 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 1-800-4264791.
MCLs
Some people may be more vulnerable to contaminants in
drinking water than the general population,
lmmunocompromised persons such as persons with cancer
undergoing chemotherapy, persons who have undergone organ
kansplants, 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. EP//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.
CustomerService
Summit Water Distribution Company employees are
dedicated to provide top quality water to every tap. We

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
