2023 Riverton City Water Consumer Confidence Report

Riverton City Water Consumer Confidence Report

Riverton City is 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 the city delivers to you each day. The city’s constant goal is to provide you with a safe and dependable supply of drinking water. Riverton City’s water is purchased wholesale from Jordan Valley Water Conservancy District and is distributed through the city’s culinary water system. Efforts are continually being made to ensure our water is clean, safe, and of the highest quality.

Why Are There Contaminants In My Drinking Water?

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 water poses a health risk. More information about contaminants and 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 water and bottled water) include rivers, lakes, streams, ponds, 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 contaminants, 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 storm water 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 agriculture, urban storm water 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 storm water 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, the 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.

Health Warning

Some people may be more vulnerable to contaminants in drinking water than the general population. Immune 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 of 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 800-426-4791.

Lead Risks and Testing

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 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 thirty seconds to two 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 at epa.gov/safewater/lead or 800-426-4791. Testing can be provided by Riverton City for a fee.

Drinking Water Contaminants

Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. More information can be obtained by calling Environmental Protection Agency’s Safe Drinking Water Hotline at 800-426-4791.

Public Participation

We invite you to learn more about opportunities for participation in decisions that affects the quality of your drinking water. Visit rivertonutah.gov/water for information, detailed water reports and upcoming projects for both culinary and secondary water.

Jordan Valley Water Conservancy District

The table on the next page 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, the data presented in this table is from testing done in the calendar year of this report. For certain parameters, the EPA and/or the State of Utah requires monitoring at a frequency less than once per year because the concentrations do not change frequently.

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 landscape 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

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.

Lead and Copper Survey

Survey’s where mail out to residents with homes built in 1989 and prior and then again a second time to residents who did not complete the survey the first time. If you still haven’t completed your survey please take afew minutes to do so. The survey is very important and the information is being required by the state of Utah and the EPA to be gathered. Riverton Water has also resorted to going door to door to those that have not completed their surveys which is using resources that could be put to other uses. If you did not recieve a survey in the mail and your home was built in 1989 or prior you can go online to rivertonutah.gov/culinary-water-pipe For more information or help call 801-208-3142 or email leadcopper@rivertonutah.gov

Where Does Your Water Come From?

Riverton purchases all of the drinking water from Jordan Valley Water Conservancy District (JVWCD) located in Bluffdale. Whose main water sources include Deer Creek and Jordenelle reservoirs, as well as the Provo River watershed, and some ground water sources/wells. In 2023 JVWCD delivered over 1.78 billion gallons of water to Riverton residents and businesses, an increase of 150 million gallons from 2022.

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. These numbers represent samples taken during the monitoring period which began in 2023 and will conclude in 2025.
