SWDC is pleased to present to you, our customer, the most current 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.
SWDC provides its consumers with both ground and surface water. Our water sources are eight
wells, Park City Water and Mountain Regional SSD. Our wells are listed as New Rest Stop,
Jeremy Ranch, White Pine, Church, Old F-7, U224, New F7, and Hi-Ute.
Lead Service Line Inventory
Service Line Inventory
Most of us have heard that lead water pipes can lead to adverse health effects. To ensure water
safety, the EPA is requiring water systems to develop a public lead service line inventory and
create a plan for identifying and mitigating lead service lines. SWDC has completed an initial lead
service line inventory, which is publicly available and can be accessed at www.summitwater.us/
service-line-survey.
Source Protection
The Drinking Water Source Protection Plan for SWDC 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 medium
level of susceptibility from potential contamination 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.
Cross Connection & Backflow Prevention
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? 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. Utah 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. Please visit the Backflow Prevention page on our website for additional
information, including answers to commonly asked questions.
Potential Health Risks
Drinking water, including bottled water, may reasonably be expected to contain at least a small
amount of some contaminants. The presence of contaminants does not necessarily indicate that
the water poses a health risk. More information about contaminants and the potential health
effects can be obtained by calling the Environmental protection Agency’s (EPA) Safe Drinking
Water Hotline at (800-426-4791). The sources of drinking water (both tap and bottled water)
include rivers, lakes, streams, 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: microbial contaminates, 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, which may come from a
variety of sources such as agricultural, urban stormwater runoff, and residential uses; organic chemical contaminants, including synthetic and volatile organic chemicals, which are by-products
of industrial processes and petroleum production, and can also come from gas stations, urban
stormwater runoff, and septic systems; and radioactive contaminants, which 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, EPA prescribes regulations that limit the amount of certain contaminants in water provided by public water systems. Food and Drug Administration (FDA)
regulations establish limits for contaminants in bottled water which must provide the same
protection for public health.
Lead
If present, lead can cause serious health problems, especially for pregnant women and young
children. Corrosion of pipes, plumbing fittings and fixtures may cause metals, including lead and
copper, to enter drinking water. To assess corrosion of lead and copper, SWDC conducts tap
sampling for lead and copper at selected sites every three years. SWDC conducted twenty lead samples during 2023. Sampling results can be obtained by requesting them at
[e-mail].
SWDC is responsible for providing high quality drinking water but cannot control the variety of
materials used in plumbing components. Lead in drinking water is primarily from material and components associated with service lines and home plumbing. 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. If 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. You can also use a filter certified by an American National
Standards Institute accredited certifier to reduce lead in drinking water. Lead in drinking water is
rarely the sole cause of lead poisoning, but it can add to a person's total lead exposure. All
potential sources of lead in the household should be identified and removed, replaced or reduced.
If you are concerned about lead in your water, you may wish to have your water tested, please contact Laramie Simmons with SWDC at 435-649-7324. Information on lead in drinking water,
testing methods, and steps you can take to minimize exposure is available at http://www.epa.gov/
safewater/lead. Some people may be more vulnerable to contaminants in drinking water than the
general population. Immunocompromised people such as people with cancer undergoing
chemotherapy, people 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]).

TEST RESULTS: SWDC routinely monitors contaminants in our drinking water in accordance with the
Federal and Utah State laws. The following table shows the results of our monitoring for 2024. It is important to
remember that all water sources of drinking water contain some naturally occurring contaminants. At low levels, these substances are generally not harmful in our drinking water. Removing all contaminants would be extremely expensive, and in most cases, would not provide increased protection of public health.

Table Definitions:
In the test results 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 in2,000,000,000 years or one penny in $10,000,000,000,000.Picocuries per liter (pCi/L) - picocuries per liter is a measure ofthe radioactivity in water.Millirems per year (mrem/yr) - measure of radiation absorbed bythe body.Million Fibers per Liter (MFL) - million fibers per liter is ameasure of the presence of asbestos fibers that are longer than10 micrometers.Nephelometric Turbidity Unit (NTU) - nephelometric turbidityunit is a measure of the clarity of water. Turbidity in excess of 5NTU is just noticeable to the average person.Action Level (AL) - the concentration of a contaminant which, ifexceeded, triggers treatment or other requirements which a watersystem must follow.Treatment Technique (TT) - A treatment technique is a requiredprocess intended to reduce the level of a contaminant in drinkingwater.Maximum Contaminant Level (MCL) - The “MaximumAllowed” (MCL) is the highest level of a contaminant that isallowed in drinking water. MCLs are set as close to the MCLGsas feasible using the best available treatment technology.Maximum Contaminant Level Goal (MCLG) - The“Goal”(MCLGthe level of a contaminant in drinking water belowwhich there is no known or expected risk to health. MCLGs allowfor a margin of safety. Maximum Residual Disinfectant Level(MRDL) - The highest level of a disinfectant allowed in drinkingwater. There is convincing evidence that addition of a disinfectantis necessary for control of microbial contaminants.Maximum Residual Disinfectant Level Goal (MRDLG) - Thelevel of a drinking water disinfectant below which there is noknown or expected risk to health. MRDLGs do not reflect thebenefits of the use of disinfectants to control microbialcontaminants.Date- Because of required sampling time frames i.e. yearly, 3years, 4 years and 6 years, sampling dates may seem out-dated.Waivers (W)- Because some chemicals are not used or stored inareas around drinking water sources, some water systems havebeen given waivers that exempt them from having to take certainchemical samples, these waivers are also tied to Drinking WaterSource Protection Plans.

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 evening•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
