Conservation
Riverton is committed to finding and implementing ways to help minimize its water footprint. Training and educating on more water friendly choices for landscaping, more efficient ways to water, updating home or business with water saving fixtures. By utilizing programs that are offered by Jordan Valley Water Conservancy District and Salt Lake County, Riverton and it’s residence can offset some of the cost of becoming more efficient and water conscientious.
Riverton City provides its consumers with 100 percent purchased water through 9 connections with Jordan Valley Water Conservancy District. Jordan Valley Water Conservancy District’s main water sources include Deer Creek and Jordanelle reservoirs, as well as the Provo River watershed, and some ground water sources/wells. JVWCD delivered over 2.02 billion gallons of water in 2024 to Riverton a increase of nearly 239 million gallons from 2023.
Corrosion Control information
Corrosion of pipes, plumbing fittings and fixtures may cause lead and copper to enter drinking water. To assess corrosion of lead and copper, Riverton City
conducts tap sampling for lead and copper at selected sites every 3 years. Riverton City has not had to treat its water to control corrosion and has not identified any corrosion issues in its system.
Lead Service Line Inventory Information
Riverton City has completed an initial Lead Service Line Inventory. The inventory is information on the service lines that connect the city’s water mainlines to the buildings/houses as well as the water pipes inside the property. The information was gathered by the following methods: Reviewed Water Department records, Visual Inspection at the Meter Pit, Customer Self-Identification, Mechanical Excavation, Vacuum Excavation, and by the states Predictive Modeling guidelines. Buildings/Houses built after April 1989 are omitted from inventory verification do to being built after lead ban was implemented. After complying with State and the EPA, Riverton’s Service line Inventory is considered Non-lead. Riverton will continue gathering the information on the address and locations the Predictive Modeling was used for.
Violations or Exceedances
Total Coliform Positive Results
Water samples taken in September 2024 had 1 sample return with a “+ coliform bacteria”. After resampling the location that had a “+” hit as well as a
connection before it, after it and the water source of where the water came from there was no sign of an issue. Retesting confirmed that total coliform bacteria was not present in the distribution system. The sample that tested positive was most likely due to contamination during the collection process. Coliforms are bacteria that are naturally present in the environment and are used as an indicator that other, potentially harmful, bacteria may be present. Total coliforms are common in the environment and are generally not harmful themselves. The presence of these bacteria can indicate that the water may have been contaminated with organisms that can cause disease. Some symptoms may include diarrhea, cramps, nausea, and possible jaundice, headaches and fatigue. When the monthly samples confirmed the presence of total coliform bacteria, we took steps to identify and correct the problem. Subsequent monthly sampling has confirmed the absence of total coliforms in the water system.
Water Source Protection Plan
The Drinking Water Source Protection Plan for Riverton City is for The Green Well and is available for your review. It contains information about source protection zones, potential contamination sources and management strategies to protect this future drinking water source. Our source has been determined to have a low level of susceptibility from potential con-
tamination sources such as The Jordan River which has varying flows and the nearby Residential homes which has uncontrolled application of Herbicides, Pesticides and Fertilizers. Riverton City has also developed management strategies to further protect our source from contamination. Please contact us if you have questions or concerns at 801-208-3162 or email water@rivertonutah.gov.
Jordan Valley Water Conservancy District has a Drinking Water Source Protection Plan. This plan covers the sources that Jordan Valley Water uses to provide water to its customers like Riverton City. Please visit Jordan Valley Conservancy District web page for more information.
Our System and its 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? 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 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.
Backflow Program
Riverton City is dedicated to providing our residents and customers with safe, clean drinking water. Maintaining a Backflow Prevention Program is an essential key to accomplishing this goal.
The city and its residents share a joint responsibility to ensure all areas of the water distribution system are adequately protected. The city will provide a safe, adequate water supply to the residents who in turn will maintain their plumbing systems in compliance with state and local ordinances, requirements, codes and policies.
Backflow incidents can seriously affect the quality and safety of the drinking water. Backflow is the reverse flow of contaminated water or other substances from a user’s water system back into the public drinking water system. This can occur if your plumbing system is physically connected (also called a cross-connection) to any source of contamination or pollution. Common examples of possible cross-connections include land-
scape sprinkling systems, hose attachments for utility sinks, and garden hoses. Backflow prevention assemblies provide the public water system with protection against contamination or pollution. Riverton City’s Water Department randomly performs assessments of every residential sprinkler irrigation system to determine compliance with the above mentioned requirements. You can email Riverton with your backflow questions anytime at backflow@riverton utah.gov
Water Monitoring and Quality
Riverton City routinely monitors contaminants in our drinking water in accordance with the Federal and Utah State laws. Table 1 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.
Jordan Valley Water Conservancy District Monitoring Data 2024
Table 3 lists all of the parameters in the drinking water detected by Jordan Valley Water Conservancy District or its suppliers in the drinking water during the calendar year of this report. The presence of these parameters in the water does not necessarily indicate that the water poses a health risk, unless otherwise noted.
Sampling Parameters
For certain parameters, EPA and/or the State requires monitoring at a frequency less than once per year because the concentrations do not change frequently.
Unregulated Contaminant Monitoring Rule “UCMR”
The Unregulated Contaminant Monitoring Rule (UCMR) is a monitoring program mandated by EPA. It requires public water systems to monitor various sites every three (3) years for different parameters selected by EPA. This rule collects occurance data on parameters that EPA is considering for regulation. Sometimes EPA includes parameters that already have an MCL but they would like to know the occurance of it at significantly lower levels than the current analytical method allows. This information can be found in Table 1 under UCMR 5 on Riverton’s report and on Jordan Valley Water Conservancy District report: Table 2.
This information represent samples taken during the monitoring period of 2024 which began in 2023 and will conclude in 2025.
Why Are There Contaminants In My Drinking Water?
Drinking water, including bottled water, may reasonably be expected to contain at least a small amount of some contaminates. The presence of contaminants does not necessarily indicate that the water poses a health risk. More information about contaminates 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.
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. Riverton City conducts its lead and copper sampling every 3 years with 2023 being its latest sampling period. During this time Riverton City collected 41 samples from its residents. Sampling results can be obtained by calling the Riverton City Water Department at 801-208-3162 or email water@rivertonutah.gov. You can also view the results online at rivertonutah.gov/water
Riverton City 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 Riverton City Water Department at 801-208-3162 or email water@ rivertonutah.gov for further information about testing. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available at 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 800-426-4791.
We at Riverton City work around the clock to provide top quality water for 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.
Chart Legend With Definitions For The Following Pages
