We’re pleased to present to you this year’s 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 sources. Our water sources are Church Well, Lyon Well, Ricks Creek Well, City Hall Well, Carrington Well, Church Main Well, and Chase Lane Well. We also purchase water from Weber Basin WCD- South (UT06013). This report shows our water quality and what it means to you our customer. The EPA has determined that your water IS SAFE at these levels.
Each year Centerville City is required to publish a Drinking Water Quality Report and make it available to all customers. It shows the test results for microbiological, inorganic, and radioactive contaminants. Centerville’s drinking water complies with all applicable standards. Testing for contaminants occurs on a regular basis-either daily, weekly, monthly, annually or every three years-depending on the substance. 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 process and protect our water resources. We are committed to ensuring the quality of your water. Most of our drinking water is groundwater from several wells. Additionally we purchase 500 acre feet of surface water from Weber Basin Water Conservancy District.
Centerville has a Drinking Water Source Protection Plan. What is a Source Protection Plan? It identifies potential sources of contamination and source protection areas. Many of our sources are in remote and protected locations where there is very little potential for source contamination. Other sources are within the range and influence of private homes, so we ask everyone to be careful with what is discharged around your yard or street such as oil, antifreeze, fertilizer, pesticides, etc. The Drinking Water Source Protection Plan is available for review at the Public Works Building located at 655 North 1250 West. For more information regarding state activities regarding source protection program, contact the Division of Drinking Water at [phone].
Centerville City is aware of the importance and value in protecting our natural resources. Therefore, we have developed management strategies to improve water quality and decrease the impact and potential contamination of sources within our watershed. These efforts are made through watershed inspections, emergency action plans, and public outreach and education. Additionally, we work to develop close partnerships with watershed stakeholders to foster participation in water quality improvement measures.
Watersheds sustain life in many ways. Successful watershed management requires suitable land use practices and water quality preservation. By implementing best practices to monitor, protect, and improve the quality of water and natural resources inside a watershed, we can sustain its future. Centerville City works hard to protect and promote the sustainability of our water resources.

Inorganic Contaminants
Centerville City Water System routinely monitors for constituents in our drinking water in accordance with the Federal and
Utah State laws. The following table shows the results of our monitoring for the period of January 1st to December 31st, 2020. All drinking water, including bottled drinking water, may be reasonably expected to contain at least small amounts of some constituents. It’s important to remember that the presence of these constituents does not necessarily pose a health risk. Test Results

Radioactive Contaminants
As you can see by the table, our system had no violations. We’re proud that your drinking water meets or exceeds all Federal and State requirements. Although some constituents have been detected, the EPA has determined that your water IS SAFE at these levels. We at Centerville City Water System work around the clock to provide top quality water to every tap. We ask that all our customers help us protect our water sources, which are the heart of our community, our way of life and our children’s future.
SAFE
Disinfection By-products
You might not be familiar with many of the terms and abbreviations in the preceding table. 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” (MCLG) 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 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 outdated.
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.
Table Definitions
Infants and young children are typically more vulnerable to lead in drinking water than the general population. It is possible that lead levels at
your home may be higher than at other homes in the community as a result of materials used in your home’s plumbing. Additional information is
available from the Safe Drinking Water Hotline [phone]). Our lead samples can be found under the inorganic contaminants section of the
test results table on page two.
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. Centerville City 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 http://www.epa.gov/safewater/lead.If you would

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 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 homes. 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
can be a cross connection if it is connected to the culinary water system. 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.
Utah & Water
Water Conservation Tips You Can Apply at Home
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. 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 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.
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]).
Should I be worried about Contaminants?
Water Conservation
As many Utahns know, we live in the second driest of the fifty United States, receiving an average of only 19.5 inches of precipitation state-wide per year. Utah’s population is increasing at a rate that our current water supply can’t sustain. We are expecting our population to double from three million to six million by the year 2060. To sustain this growth water providers
will need to find more sources of water. The cheapest and least invasive of these is water conservation. The cost to conserve water is minimal compared to the cost of building new infrastructure.
Every Drop Counts!
Centerville City closely monitors all the water it treats and is confident about the high quality of water delivered to your homes and businesses. We all must rethink how we use water and challenge ourselves to preserve this resource for years to come. Rethinking outdoor water use is by far the area with the most potential for savings. The state is asking the water
users of Centerville City to reduce per capita water use another 20% from now until 2030, through education and conservation programs. This info comes from Weber Basin WCD Water Quality Report.
With increasing growth and the nature of the regional climate, there is no question that we will encounter future drought in the coming years. Future drought cycles will have an even greater effect than in previous years due to increased population and higher demands by private and commercial water users. Applying principles of conservation and improving our
water efficiency must become a way of life for everyone. Centerville City is making extended efforts in water conservation by improving existing infrastructure, adopting new technol-ogy, and hosting educational opportunities for the public.
Conservation alone will not meet future water needs. Centerville City & Weber Basin District will continue to develop water supplies, build new infrastructure, and maintain the current infrastructure. However, future water projects are costly and usually geographically limited. The more each of us can do to be efficient with our current water supply will help delay and
minimize the cost of future projects. If we each save a little, we all can save a lot!
Achieving this goal will be extremely difficult and will take a significant effort from all water users within the City. This water conservation effort will be a major focus of the city moving forward by educating water users on proper irrigation practices and changing both attitudes and behaviors toward wiser water use. We are grateful to those who are already making efforts to improve efficiency and conserve this valuable resource.
You can also learn about yard and conservation tips by visiting Weber Basin WCD’s learning garden. The learning garden has classes and events to help make the most of your water and while enjoying your yard and garden throughout the year.

GOVERNOR COX’S DROUGHT STATE OF EMERGENCY With 100% in the moderate drought category and 90% of the state experiencing extreme drought, today Gov. Spencer J. Cox issued an Executive Order declaring a state of emergency due to drought conditions. This declaration allows drought-affected communities, agricultural producers and others to officially begin the process that may provide access to state or federal emergency resources. Current soil moisture is also at the lowest levels since monitoring began in 2006. Governor Cox has recommended the following practices to conserve our precious water resources during this dry time; Please wait to water as long as you can, shorten showers by at least one minute, and fix any leaks and update infrastructure as needed. State and local governments may instill strict watering guidelines this summer to slow the flow. Please adhere to the applicable rules.
