Is My Water Safe?

Last year, as in years past, your drinking water met all U.S. Environmental Protection Agency (EPA) and State
drinking water health standards. Tooele City safeguards its water supplies and we are proud to report that our system
has not violated a Maximum Contaminant Level (MCL) or any other water quality standard. This report is a
summary of last year’s drinking water quality test data. Included are details about where your water comes from,
what it contains, and how it compares to EPA and State standards.

Where Does My Water Come From?

Your drinking water during the reporting year 2024 came from twelve (12) wells and two (2) springs. The City
controls the land around these wells and springs to restrict any activity that could contaminate them. The City also
relies upon accepted Drinking Water Source Protection zones which have been approved and accepted by the State
and which are protected by both City and County Land Use Ordinance. The water that comes out of these wells and
springs is disinfected to protect you against contaminants.

Why Are There Contaminants in My Drinking Water?

All sources of drinking water are subject to potential contamination by constituents that are naturally occurring or
manmade. 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, or at the following link:

https://www.epa.gov/ground-water-and-drinking-water/safe-drinking-water-information

Locally, sources of drinking water include 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, radionuclides. Water can also pick
up substances resulting from the presence of animals or human activity.

Contaminants that may be present in water include:
• Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment
plants, septic systems, agricultural livestock operations, and wildlife.
• Inorganic contaminants, such as salts and metals, can occur naturally or result from urban storm
water runoff, industrial or domestic wastewater discharges, oil and gas production, mining, and/or
farming.
• Pesticides and herbicides come from a variety of sources such as agriculture, urban storm water
runoff, and residential uses.

• Organic chemical contaminants, including synthetic and volatile organic chemicals, are byproducts
of industrial processes and petroleum production, and can also come from gas stations, urban storm
water runoff, and septic systems.
• Radionuclides can be naturally occurring or the result of oil and gas production and mining activities.
• Disinfection byproducts derived as a result of chlorination and disinfection of the water.

In order to ensure that water is safe to drink, the State and the EPA establish regulations which limit the amount of
certain contaminants in water provided by public water systems.

Tooele City Water Quality Data

The EPA requires monitoring of more than 90 drinking water contaminants according to a sampling schedule
established by the State Division of Drinking Water. The table below lists all of the required drinking water
contaminants that were detected during the calendar year of this report, as well as the most recent water quality data
of other contaminants detected within the past 5 years. The presence of contaminants in the water does not
necessarily indicate that the water poses a health risk. The EPA and/or the State do not require us to monitor for
certain contaminants every year because the concentrations of these contaminants do not change frequently and
have been demonstrated over time as meeting drinking water standards. The values shown in the table below reflect
the highest reported level for the contaminants identified, and are often much lower.

Terms and Abbreviations Used
AL (Allowable Limit): The level of a contaminant which, if exceeded, requires treatment or additional
monitoring.
DL (Detection Limit): The minimum contaminant limit which the testing laboratory is able to detect.
MCL (Maximum Contaminant Level): The highest level of a contaminant that is allowed in drinking
water.
MCLG (Maximum Contaminant Level Goal): The maximum level of a contaminant in drinking water at
which no known or anticipated adverse effect on the health of persons would occur, allowing an
adequate margin of safety.
MRL (Minimum Reporting Level): The contaminant level which is required to report to the State.
NA (Not Applicable): No contamination level established
ND (Non Detected): Laboratory analysis indicates that the constituent is not present.
NTU (Nephelometric Turbidity Unit): NTU is a measure of the clarify of water.
mg/l milligrams per liter, or parts per million.
ug/l micrograms per liter, or parts per billion.

The above tables report all of the required drinking water contaminants that were detected during the calendar year
of this report, as well as the most recent water quality data of other contaminants within the past 5 years. All water
utilized for culinary purposes within Tooele City was tested by methods in accordance with State and Federal
Standards, and meets State and Federal requirements.

How Can I Get Involved?

The best way to get involved in helping protect your water from contamination is pollution prevention. Your water
sources can be affected by chemicals and pollutants that are not handled properly. Some of the most common
sources of contamination include: dry cleaning chemicals, fertilizers and pesticides, oil and gasoline, paints,
solvents, and garbage. Fertilizers and pesticides should be applied in accordance with manufacturers’ label
instructions. It is also very important to store and dispose of these materials and any other potential contaminant in a
proper and safe manner. Just one gallon of gasoline can pollute 600,000 gallons of water. Once a water source is
polluted, it could take decades and millions of dollars to be able to use it again.

Another way you can get involved is by participating in City Council and Planning Commission meetings. City
Council meetings are generally held the first and third Wednesdays of each month. Planning Commission meetings
are generally held on the second and fourth Wednesdays of each month. Further information regarding these public
meetings is available on the Tooele City web page (https://tooelecity.gov/). Get involved by doing your part to
protect our water resources.

Important Health Information

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 from infections. These people should seek advice about drinking water from their health care providers.
EPA/CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial
contaminants are available from the Safe Drinking Water Hotline at 1-800-426-4791.

Septic Tanks / Holding Tanks:

Septic systems can contaminate ground water if they are misused, improperly maintained, or improperly constructed.
The major contaminant discharged from septic systems is disease-causing germs. These germs (bacteria and viruses)
- can cause many human diseases. Another contaminant discharged from septic systems is nitrogen in the form of
nitrate. If the nitrate level of drinking water is too high, infants, up to the age of six months old, can develop a fatal
disease called blue baby syndrome (methemoglobenemia). Additionally, if toxic chemicals are disposed in a septic
system, they can percolate through the drainfield and into the ground water. Additional information regarding best
management practices for septic tanks / holding tanks is available at the following link:
https://documents.deq.utah.gov/drinking-water/rules-implementation/DDW-2019-008508.pdf

Lead

Service Line Inventories

Tooele City has completed an initial lead service line inventory. This inventory includes information on the service
line material that connects water mains to buildings/houses. This inventory can be accessed by contacting Tooele
City Public Works at 435-843-2130 or emailing a request to [e-mail]

Results of Lead and Copper Samples Collected That Year

Thirty lead samples were collected during 2023. Sampling results can be obtained by calling Tooele City Public
Works at 435-843-2130 or emailing a request to [e-mail]

Updated Mandatory Health Effects Language

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. Tooele City is
responsible for providing high quality drinking water and removing lead pipes, but cannot control the variety of
materials used in plumbing components in your home. 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. Before drinking tap water, flush your
pipes for several minutes by running your tap, taking a shower, doing laundry or a load of dishes. You can also use a
filter certified by an American National Standards Institute accredited certifier to reduce lead in drinking water. If
you are concerned about lead in your water and wish to have your water tested, contact Tooele City Public Works at
435-843-2130. 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.

IMPORTANT INFORMATION ABOUT YOUR DRINKING WATER
Monitoring Requirements Not Met for Tooele City

Our water system violated several drinking water standards over the past year. Even though these were not
emergencies, as our customers, you have the right to know what happened and what we did to correct these
situations.

We are required to monitor your drinking water for specific contaminants on a regular basis. Results of regular
monitoring are an indicator of whether or not our drinking water meets health standards. During the 2024 calendar
year we did not complete all monitoring for pesticides in two of our sources and radionuclides in one of our sources
and therefore cannot be sure of the quality of our drinking water during that time.

What should I do?

There is nothing you need to do at this time.

The table below lists the contaminants we did not properly test for during the last year, how often we are supposed to
sample for these contaminants and how many samples we are supposed to take, how many samples we took, when
samples should have been taken, and the date on which follow-up samples were taken.

What happened? What is being done?

Three water samples were missed during our third-quarter testing. As soon as we became aware of the issue, we
immediately collected the samples and submitted them for analysis. All results came back meeting water quality
standards.
