Commitment to Quality

Park City Water Department is committed to providing the highest quality drinking water and the best service to our customers. We take pride in protecting public health through our continual efforts to provide safe and reliable water to your homes and businesses. The Water Department performs hundreds of different tests on a regular basis to ensure the water you are drinking meets or is better than the standards set by the Environmental Protection Agency (EPA) and the Utah Department of Environmental Quality Division of Drinking water (DDW). Water Department staff works closely with DDW to make certain all drinking water standards are met every time you open a tap at your home or business.

See below information about our Annual Drinking Water Quality Consumer Confidence Report which provides information about the sources of water, water quality testing results and the treatment facilities that are operated by Water Department staff in addition to other EPA required information.

Annual Water Quality Consumer Confidence Report

The Park City Water Department, as required by the United States Environmental Protection Agency (EPA) and the Utah State Division of Drinking Water (DDW), annually publishes the Water Quality Consumer Confidence Report (CCR) (Leer en Español). The CCR provides information about the sources of water and the treatment facilities that are operated by Water Department staff in addition to other EPA required information. The CCR reports the highest and lowest levels of each parameter that is detected from the sources that supply water to the distribution system. Many other parameters are tested for and if they are not detected EPA recommends against including these parameters in the CCR. The CCR also includes results for some parameters that are collected in the distribution system, such as total coliforms, chlorine residuals, disinfectant by-products, and others from within buildings, such as lead and copper.

Water Service Line Material Inventory Available to the Public

All water systems, including Park City Water, are required by the EPA and Utah Division of Drinking Water (DDW) to provide an inventory of all water service lines materials, with an initial survey due by October 2024. In advance of this deadline Park City completed and submitted the initial inventory to DDW by identifying the service line material or that it is not lead on both the property owner and City side of the meter. Based on our records review, customer surveys and City inspections, Park City is confident that we do not have any lead service lines. Additionally, there are no galvanized service lines that are or were ever downstream of a lead service line. EPA requires that this inventory be available to the public. If you are interested in reviewing the inventory or specific information related to it, please contact Water Quality and Treatment Manager, Michelle De Haan, at 435-615-5340 or michelle.dehaan@parkcity.org.

PFAS in Well Water, Park City is first community to gain PFAS Compliance Plan approval from Utah Division of Drinking Water

In April of 2024 the Environmental Protection Agency (EPA) finalized Drinking Water regulatory standards for a group of chemicals called per-and polyfluoroalkyl substances (PFAS), commonly known as “forever chemicals.” PFAS are a large family of synthetic chemicals that have been used in a wide variety of consumer products and industrial processes since the mid-20th century. The EPA has determined that PFAS in drinking water and other sources can cause serious health problems if you are exposed to them over a long period of time. 

PFAS detected in Park City’s well water has been found to be above the new standards. Fortunately, PFAS has not been found in any of our other drinking water sources which are treated at the new 3Kings WTP and the Quinn's Junction WTP. With the 3Kings WTP now delivering drinking water, we are able to reduce our reliance on well water and are on track to achieve compliance with the new rule.

Park City is the first water system in Utah to receive approval of its PFAS compliance plan from the Utah Division of Drinking Water (DDW), 4.5 years before EPA’s 2029 compliance deadline. EPA’s PFAS regulations were published in April of 2024. Park City in May of 2023 applied to the Utah DDW to comply with the new standards utilizing blending to achieve compliance with the new PFAS standards. Blending is a common practice for achieving compliance with many drinking water contaminant limits. Two wells with PFAS at the Creekside WTP are being blended with PFAS-free 3Kings WTP water in a pipeline to achieve standards below the new EPA limits before it is delivered to households. In September of 2024, Utah DDW approved the blending plan. In September of 2024, Park City Scientists tested at the blending compliance location and verified the blending plan achieves compliance with results below the new PFOS and PFOA 4 parts per trillion Maximum Contaminant Levels (MCLs). The City will continue to test and verify it can continually achieve compliance with the PFAS MCLs by blending, in advance of the EPA’s 2029 PFAS compliance deadline.

We recommend reading this EPA webpage which outlines, “Meaningful and Achievable Steps You Can Take to Reduce Your Risk and Limit Your Exposure to PFAS” from many routes of exposure and this EPA document regarding home treatment devices that remove PFAS:  Water Filter Fact Sheet.

We have identified that fluoro ski wax is the probable contamination source and have been working diligently to reduce the continued impact on our water supplies by prohibiting it by ordinance and partnering with the community and retailers on a ski wax take back program and encouraging everyone to ski fluoro-free. For more information go to engageparkcity.org/ski-wax.

Ski Wax Take Back Program We are proud of the community for turning in 600 pounds of Fluoro ski wax, the probable source of PFAS detections in well water.

Water Quality in your Neighborhood

As part of Park City Water Department's commitment to water quality, testing has been significantly expanded beyond that required by EPA and DDW. Samples are being collected within the distribution system at locations that represent water being delivered to homes and businesses throughout the system. For Information about Water Quality in Your Neighborhood click here.

Home & Business Owner Responsibilities – Been Away? Flush Your Pipes

Many of Park City’s 2^nd homes and seasonal businesses are unoccupied for extended periods. Park City's Water Department is dedicated to delivering high quality drinking water, and it is important homeowners and businesses understand their responsibility beyond the meter to ensure continued high quality drinking water at the tap. Past the meter, each customer is responsible for the quality of its water. Park City water quality staff has guidance for home and business owners to maintain good water quality inside their homes and businesses. If a home or building has been empty or under used for months, it’s important to “flush the water lines” to move out the older water and bring in fresh water. The quality of the water that’s been sitting in the internal plumbing of an empty or under-used home or building can decline, creating taste and odor issues, discolored water, and potentially bacteria growth. It’s important to move out that older water and bring in a fresh supply.

Who Should Flush - Any home, facility, business, school, or office building that has been empty or under used for months.

What to Flush - All appliances that use water including faucets, drinking water fountains, kitchen sprayers, dishwashers, ice makers, toilets, hot water heaters, spas, and decorative water features.

How to Flush – Park City Water’s step-by-step infographic (below), adapted from Louisville Water, and their animated video helps guide customers through the flushing process.

Cross Connection Control & Backflow Program
