2020 Water Quality Report
D. Blair CampMurray City Mayor
Dear Murray City Water Customer:
Murray City is pleased to distribute its annual Water Quality Report for calendar year 2020. The report contains information about Murray City’s water quality and provides a way for the City to share ideas with our customers, such as the importance of water conservation. The City continues to evaluate new and efficient ways to help conserve water and protect our most precious natural resource, and I ask for your continued support of these efforts. Murray City’s water supplies remain safe, with the water department taking 40 investigative water samples every month at various locations throughout the water system, looking for any possible signs of contamination. Regular sampling is required by the Division of Drinking Water, and Murray City will continue with careful monitoring in the future. As in prior years, you will notice as you review the report that we have included some remarkable pictures from the Murray School District’s 4th grade classes. The featured drawings are from a recent art contest sponsored by the Murray City Water Division in conjunction with the National Energy Foundation. I invite you to take a few minutes to read through this report, admire the artwork, and hopefully, learn something new and interesting about our water quality and ways you can conserve. I also encourage you to visit the murray.utah.gov website, where you will find information about our rebate programs and the current Water Conservation Plan.
Sincerely,
Murray City Water Department

Watering of lawns between the hours of 10:00
am to 6:00 pm is against city Ordinance
13.08.120. This was put in place in 2018 to be
in line with state water management guidelines
to help conserve water.

Water Conservation
Sprinkler Spruce-Up!The onset of warmer weather can lead to an increase in landscape irrigation. Before you ramp up your watering, be sure to spruce up your irrigation system. System maintenance can help save you a lot of money and water! Cracks in pipes can lead to costly leaks, and broken sprinkler heads can waste water and money. You could be losing up to 25,000 gallons of water and $280 over a six-month irrigation season!
• Inspect. Check your system for clogged, broken or missing sprinkler heads. Better yet, go with a pro—find an irrigation professional certified by a WaterSense labeled program to do the work for you.
• Connect. Examine points where the sprinkler heads connect to pipes/hoses. If water pools in your landscape or you have large soggy areas, you could have a leak in your system. A leak about as small as the tip of a ballpoint pen (or 1/32nd of an inch) can waste about 6,300 gallons of water per month.
• Direct. Are you watering the driveway, house, or sidewalk instead of your yard? Redirect sprinklers to apply water only to the landscape.
• Select. An improperly scheduled irrigation controller can waste a lot of water and money. Update your system’s schedule with the seasons, or select a WaterSense labeled controller to take the guesswork out of scheduling.

2020 Water Quality Report
Toilets are by far the main source of water use in the home, accounting for nearly 30 percent of an average home’s indoor water consumption. By replacing old, inefficient toilets (1.6 gallons per flush or more) with WaterSense labeled models (1.28 gallons or less), the average family can reduce water used for toilets by 20 to 60 percent—that’s nearly 13,000 gallons of water savings for your home every year!

WaterSense Rebate Programs©
A clock-timer-controlled irrigation system that isn’t properly programmed or maintained can waste as much as 25,000 gallons of water annually.Smart irrigation controllers can help save water by automatically adjusting watering schedules based on local weather and landscape needs.
Inefficient showerheads not only waste water, they waste energy used to heat that water. But every time you take a shower with a WaterSense labeled showerhead, you can save energy—equal to the amount of electricity it takes to light a 60-watt light bulb for 8 hours.

Products that have earned the WaterSense label have been indepently certified to use at least 20 percent less water and perform as well or better than standard models

Information provided by the American Backflow Prevention Associationhttp://www.nobackflow.com/abpaback.htm
What is Backflow?
Water distribution systems are designed with the intention of
the water flowing to the point of use, or from the City’s main to
the customer. However, hydraulic conditions within the system
may deviate from “normal” conditions, causing water to flow in
the opposite direction. This undesirable flow reversal of water is
called backflow.
Backflow can cause the drinking water system to become polluted
or contaminated.
Does Water Ever Flow Backwards?
Hose Bib (Hose Attached) Vacuum Breakers (HAVB)
Water users commonly use garden hoses for a variety of purposes,
including:
• Watering lawns, flower beds and gardens.
• Washing cars and other items.
• Filling pools and hot tubs.
• Washing workshops, garages, food prep
areas, etc.
• Applying liquid fertilizers and pesticides.
Any of these may involve attaching a
chemical reservoir to the end of the hose
(If at all possible avoid this practice!). In
each of these cases, there is the potential
to contaminate the water supply. Hose
Bib Vacuum Breakers are simple, low-cost
devices that should be used to help prevent
backflow of water when
engaging in the use of water
hoses. They are easy to
install and available at many
plumbing supply stores.
2020 Water Quality Report
Murray City offers two non-fluoridated water sources to those who
would like to fill containers for drinking water. One site is located at
8 East 6100 South, the other is located at 630 East 5400 South.
Non-fluoridated Water
On October 1st 2003, Murray City began adding fluoride to the drinking water supply. This came about because of the passage of a ballot initiative in 2000. Murray voters passed the initiative by a 53% margin.
Fluoride is a naturally occuring mineral and, with a few exceptions, almost all water has some fluoride in it.
Murray City’s water system has a natural fluoride level average of .25 ppm (parts per million). In accordance with Salt Lake Valley Health Department regulations, Murray Water Department adds enough fluoride to the water to bring the combined level between the mandated range of .6 to .9 ppm.
Fluoridation
Murray Water Department takes more than 100 samples each month to make sure that your drinking water is safe. We monitor to make sure levels of chlorine and disinfectant bi-products are at safe levels and to check for other dangerous bacteria and viruses. We also monitor many natural contaminants including lead and copper.
Water Testing
Murray City Water Department
Lead in Drinking Water
Lead is a naturally occurring element found in small amounts in the earth’s crust. While it has many beneficial uses, it is known to be harmful to human health if inhaled or ingested in large amounts, especailly in young children and pregnant women.
Lead exposure can come from all parts of our environment - air, soil and dust, food, and water. Although Murray City water is well below the acceptable limits, lead can enter drinking water through the corrosion of plumbing materials inside the home.
The longer the water has been sitting in your home’s pipes, the more potential lead has to leach from plumbing fixtures. You can minimize the potential for lead exposure by flushing your cold water tap until the water becomes cold before using water for drinking or cooking.
You can find more information on lead in drinking water at www.epa.gov/lead/learn-about-lead or from the Safe Drinking
Water Hotline [phone]

2020 Water Quality Report
All drinking water, including bottled water, may reasonably be
expected to contain at least small amounts of contaminants. It is
important to remember that the presence of these contaminants
does not necessarily pose a health risk.
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 health care providers. EPA/
CDC guidelines on appropriate means to lessen the risk of
infection by Cryptosporidium and other microbial contaminants are
available from:

2020 Water Quality Report
This chart lists the most recent test results for Murray Cityfacilities and indicates the most likely source of contamination. The data is a range for all wells and springs with the lowest and highest levels.
Maximum Contamination Level (MCL) is the highest level of contaminant that is allowed in drinking water. Using the best available technology, MCL’s are set as close to the goal as feasible. Maximum Contaminant Levels Goal (MCLG) is the level of a contaminant in drinking water below which there is no known or expected health risk. MCGL’s allow for a margin of safety. In addition to the parameters listed in this report, Murray City monitors for many unregulated contaminants. The results are
available at the Public Services office.
