Christiansen Regional Water Treatment Plant Consumer Confidence Report 2023 www.cuwcd.com | 1 About Our Water Treatment Plant The Utah Valley Water Treatment Plant (UVWTP) underwent construction in 1977 and began treating water from the Provo River on August 1, 1979. At the time, the UVWTP could treat up to 42 million gallons of water per day (MGD) through direct filtration. In 2002, construction of a new update was completed which expanded the plant’s capacity to 80 MGD. In January of 2016, another update was completed which added additional water treatment processes to make the plant conventional and expanded the capacity to 100 MGD. The UVWTP was officially renamed to the Don A. Christiansen Regional Water Treatment Plant (DACRWTP) in honor of the former general manager of the Central Utah Water Conservancy District. The DACRWTP is a wholesaler facility that provides drinking water to several municipalities and other conservancy districts for distribution to their customers. Today, the DACRWTP and its crew of operators serve to provide people in Utah County and Salt Lake Counties, clean drinking water. Our drinking water is sourced from the Provo River watershed from the Olmstead Diversion located about 7 miles downriver from Deer Creek dam. Upon arrival to the plant, water is first treated with ozone to remove contaminants associated with taste and odor issues and to inhibit the formation of harmful disinfection byproducts. Next, organic molecules and other contaminants are removed from the water through coagulation, flocculation, sedimentation, and filtration processes. Finally, chlorine is added to disinfect the water after the treatment process. We are proud of the water we produce and strive to maintain a culture of excellence. This year, the DACRWTP operators celebrated a new milestone when the plant extended its own record of 5244 consecutive days of producing finished water with a turbidity of < 0.10 NTU.

Together, these agencies have established limits on the contaminants that may be present in drinking water. Here at the DACRWTP, we take these rules and regulations very seriously. We routinely monitor for regulated as well as unregulated contaminants beyond requirement to ensure that we are delivering the safest drinking water possible. Additionally, we diligently monitor water quality in the watershed and are continually conducting our own research and development to ensure that our processes are optimized. Because of our passion for water quality, we have joined with other like-minded water utilities, both locally and nationally, to hold ourselves to a higher standard. Together, we set goals that are stricter than regulations and collaborate to achieve these goals. On February 12, 1997, the DACRWTP joined The Partnership for Safe Water, an alliance comprised of more than six drinking water organizations such as the AWWA and the USEPA and over 200 utilities. The goal of the Partnership for Safe Water is to implement voluntary programs of excellence and preserve public health by setting standards where regulation may not exist. There are four phases in the Partnership for each member utility. Phases I-III are membership requirements and include maintaining compliance with all regulations, continual data collection to guide process optimization efforts, and a self-assessment of performance. In 2003, the Don A. Christiansen Regional Water Treatment Plant became the second plant in the nation to receive the rarely achieved and voluntary Phase IV “Excellence in Water Treatment” award from the Partnership. The final phase was a demonstration to the other Partnership peers and organizing bodies that the DACRWTP meets all the stringent goals through plant optimization and performance. In 2023, the DACRWTP celebrated its 20th year of maintaining its Phase IV award from the Partnership. 4 CUWCD | CCR 2023 Watershed Protection Watersheds are defined as geographical divisions which collect a unifying flow of both surface and groundwater into one basin, river, reservoir etc. The Provo River watershed is just one of the thousands of watersheds in North America but is the primary source for drinking water for the majority of Utahns. We are working closely with the Utah Division of Water Quality, other conservancy districts, municipalities, and other members of private and public organizations to protect our watershed. Through alliances such as the Provo River Watershed Council we collect and share data to continue to protect our resources. As part of the Provo River Watershed Council, we promote and support watershed best management practices through partnerships and collaboration, education, and water quality monitoring. These efforts help ensure high quality source water for the DACRWTP. Through these collaborative efforts, we have established a source water protection plan that can be viewed on our website: For any questions about the plan, please contact our Watershed Programs Manager: Joe Crawford (801)-226-7113 joe@cuwcd.gov https://cuwcd.gov/resources.html Provo River Watershed Council If you would like to learn more about watershed protection visit our website: ProvoRiverWatershed.org www.cuwcd.com | 5 Our CWP Team The Central Utah Water Development Project, or CWP, was created to provide water to communities in north Utah County and Salt Lake County. In 2005, Central Utah Water Conservancy District purchased 42,400 acre feet of water rights and other water assets from Geneva Steel. From these acquisitions, 15 well sites have been planned while eight have been fully drilled and developed. Additionally, 23 miles of pipeline, 10 million gallons of storage, a pump station and chlorination facilities are able to provide cities such as Saratoga Springs, Eagle Mountain, Lehi, Vineyard, and even Jordan Valley Water Conservancy District with 53,312 acre feet of water annually. The other wells will be developed as the need for water in the communities served by CWP increases. Our CWP wells are some of the deepest in Utah at approximately 1500 feet deep! Water from this deep ground aquifer is of incredibly high quality (see pages 10– 12) and has won several awards for best tasting groundwater at the AWWA Intermountain Section Conference. 6 CUWCD | CCR 2023 A Message from the EPA In order to ensure that tap water is safe to drink, EPA prescribes regulations which 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. 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. 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 may pick up substances resulting from the presence of animals or from human activity. Contaminants that may be present in source 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, 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 agriculture, 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. 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 about drinking water from their health care providers. EPA and Center for Disease Control (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 (800.426.4791). www.water.epa.gov Safe Drinking Water Hotline (800)-426-4791 www.cuwcd.com | 7 DACRWTP Finished Water UNITS 2023 AVERAGE 2023 RANGE MONITORING CRITERIA LIKELY SOURCE(S) / COMENTS Unless noted otherwise, the data presented in this table are from testing conducted in 2023MCL MCLG MICROBIOLOGICAL Total Coliform % positive per month 0 0 5% 0 Coliforms are naturally present in the environment; as well as feces; fecal coliforms and E.coli only come from human and animal fecal waste.
