2022 Quality on Tap Report for Roy City


We’re pleased to present you with this year’s Annual Water Quality Report. This report is designed to inform you about our excellent water quality and the services we have delivered to you over the past year. Our goal has always been to provide you with a safe and dependable drinking water supply. Our water sources are contracted water from Weber Basin Water Conservancy District and four deep wells.

We’re pleased to report that our drinking water meets federal and state requirements for 2022. This report discloses our water quality and what it means to you, our customer.

The Drinking Water Source Protection Plan for Roy City is available for your review. It contains information about source protection zones, potential contamination sources, and management strategies to protect our drinking water. Gas stations, lawn care companies, and Hill Air Force Base’s underground contamination are potential contamination sources common in our protected areas. Additionally, our wells have a low susceptibility to potential contamination, and we have also developed management strategies to further protect our sources.

Water quality inside your home is always a concern. You should occasionally check your water heater for proper temperature settings. Water that is too hot can cause a burn hazard, and water that is lukewarm can create a perfect environment for bacterial growth. You should clean, maintain and replace filters and purifiers according to the manufacturer’s recommendations to ensure they continue to operate as intended. The water hardness in Roy City can range from 10 to 18 grains per gallon, therefore it is important to monitor the setting on your water softener regularly to ensure you are treating your water properly and not wasting money by overtreating. Remember to maintain your pressure regulator on your main supply line to ensure it continues to work properly to get the water supply you need.

If you have any questions about this report or concerning your water utility, please contact the Roy City Public Works office at 801-774-1090, address 5460 South 2700 West, Roy, Utah 84067. We want our valued customers to be informed about their water utility. If you would like to attend any of our regularly scheduled City Council meetings, they are held on the first and third Tuesday of each month, 6 p.m., at the Roy City Municipal Center, address 5051 South 1900 West, Roy, Utah 84067.

All sources of drinking water are subject to potential contamination by constituents that are naturally occurring or man-made. Those constituents can be microbes, organic or inorganic chemicals, or radioactive materials. All 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 the water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the Environmental Protection Agency’s Safe Drinking Water Hotline at 800-426-4791.

MCLs are set at very stringent levels. To understand the possible health effects described for many regulated constituents, a person would have to drink 2 liters of water every day at the MCL level for a lifetime to have a one-in-a-million chance of having the described health effect.

Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-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 from infections. These people should seek advice about drinking water from their healthcare providers. 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 at 1-800-426-4791.

We at the Roy City Water Department, 801-774-1090, work around the clock to provide top-quality water to 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.

In addition to the sampling outlined in the table above, we have also sampled for 21 Volatile Organic Chemicals, 28 Pesticides, 35 Unregulated Organic Chemicals, and 10 Unregulated Pesticides. These additional chemicals were not detected in our water. The following constituents are regulated more closely: Arsenic, Lead, Nitrate, Radon, and Cryptosporidium. Notice of any detection is required.


  • Non-Detects (ND) – Laboratory analysis indicates the constituent is not present.
  • ND/Low-High – For water systems that have multiple sources of water, the Utah Division of Drinking Water has given water systems the option of listing the test results of the constituents in one table, instead of multiple tables. To accomplish this, the lowest and highest values detected in the multiple sources are recorded in the same space in the report table.
  • Parts per million (ppm) or Milligrams per liter (mg/L) – One part per million corresponds to one minute in two years or a single penny in $10,000.
  • Parts per billion (ppb) or Micrograms per liter (ug/L) – One part per billion corresponds to one minute in 2,000 years or a single penny in $10,000,000.
  • Picocuries per liter (pCi/L) – A measure of the radioactivity in water.
  • Action Level (AL) – The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.
  • Treatment Technique (TT) – A required process intended to reduce the level of a contaminant in drinking water.
  • Maximum Contaminant Level (MCL) – The “maximum allowed” is the highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology.
  • Maximum Contaminant Level Goal (MCLG)- The “goal” is the level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety.
