2018 Roy City Consumer Confidence Report

We’re pleased to present you this year’s Annual Water Quality Report. This report is designed to inform you about our excellent water quality and services we have delivered to you over the past year. Our goal is, and always has been, to provide you with a safe and dependable supply of drinking water. Our water sources are mostly contracted water from Weber Basin Water Conservancy District and 4 deep wells.

We’re pleased to report that our drinking water met federal and state requirements during 2018. 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. Potential contamination sources common in our protection areas are gas stations, lawn care companies, and Hill Air Force Base’s underground contamination. Additionally, our wells have a low susceptibility to potential contamination. We have also developed management strategies to further protect our sources from contamination.

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 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, 5:30 p.m., at the Roy City Municipal Center, address 5051 South 1900 West, Roy, Utah 84067.

Roy City routinely monitors for contaminants in our drinking water in accordance with the Federal and Utah State laws. EPA requires monitoring of over 80 drinking water contaminations. Those contaminates listed in the table below are the contaminants detected in our drinking water; the table shows the results of our monitoring for the period of January 1st to December 31st, 2018.


Non-Detects (ND) – laboratory analysis indicates that the contaminant 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 contaminants 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.

MCLs are set at very stringent levels. To understand the possible health effects described for many regulated contaminants, 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.

All sources of drinking water are subject to potential contamination by contaminants that are naturally occurring or are man-made. Those contaminants can be microbes, organic or inorganic chemicals, or radioactive materials. 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 1-800-426-4791.

Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised person 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/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 contaminants are regulated more closely: Arsenic, Lead, Nitrate, Radon, and Cryptosporidium. Notice of any detection is required.
