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.

PFAS in Groundwater

June 15, 2022, the United States Environmental Protection Agency (USEPA) issued new interim lifetime Health Advisories (HAs) for two man-made chemicals in drinking water and finalized two HAs for two other chemicals.  All four chemicals are part of a group of chemicals commonly referred to as PFAS, which stands for “per- and polyfluoroalkyl substances”. This action is relevant to Park City because the groundwater we extract from three of our wells contains measurable levels of two PFAS, specifically perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS), that are above the interim HAs announced by the USEPA. By nature of what a lifetime HA is, the presence of PFAS in the City’s groundwater at the levels noted below by no means constitutes an immediate threat to public health. By all measures, the City’s groundwater remains fully suitable for consumption by the City’s residents and businesses. Nonetheless, the City takes this development seriously and will be working with the State of Utah’s Department of Environmental Quality’s Division of Drinking Water (DDW) to identify and implement a proper response. Our water quality scientists are evaluating the potential that fluorocarbon ski wax may be responsible for low level PFAS concentrations in groundwater. For more information, click here.

Fluorocarbon ski wax is likely responsible for low-level PFAS contamination in our groundwater. Due to this environmental threat, Recycle Utah has begun a Ski Wax Take Back Program to dispose of these contaminants.

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 2nd 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

Park City Public Utilities works hard to ensure the safety of your drinking water. Our Cross-connection control and Backflow Prevention Program plays a vital role in preventing contamination of drinking water caused by backflow through a metered connection. For more information click here.
