Annual Drinking Water Quality Report
The Water We Drink 2020
Maeser Water is pleased to present this year's Annual Water Quality Report (Consumer Confidence Report) as required by the Safe Drinking Water Act (SDWA). This report is designed to
provide details about where your water comes from, what it contains, and how it compares to standards set by regulatory agencies. This report is a snapshot of last year's water quality.We
are committed to providing you with information because informed customers are our best allies.
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:

The District has three sources of water. The two main sources are the Ashley Valley Water Treatment Plant (AVWTP) operated by the Central Utah Water Conservancy District and the Ashley
Springs Water Treatment Plant operated by Ashley Valley Water and Sewer Improvement District (AVWSID). The AVWTP plant processes water from Red Fleet Reservoir as well as Ashley Springs.
The AVWSID plant treats water from Ashley Springs. Ashley Springs receives its water from Dry Fork Creek, which sinks into a limestone formation and resurfaces in the Ashley Springs.The
third source is the Painted Hills Well. The water for this well comes from an underground aquifer that is over 1500 feet deep. This source is used as a backup source in the event that
part of the system is cut off from Ashley Springs or Red Fleet and is very limited in capacity. The Painted Hills Well was not used in 2020.
There are source protection plans for each source the District gets water from. The Ashley Springs and Painted Hills Well source protection plans can be viewed at the District office
during regular business hours. The Red Fleet source protection plan was created by the Central Utah Water Conservancy District. The Maeser Water Improvement District conducts Source
Water Assessments to monitor the potential for contamination in the protection area.
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 water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the EPA’s Safe Drinking Water Hotline: [phone].
The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells.As water travels over the surface of the land or
through the ground, it dissolves naturally occurring minerals and, in some cases, radioactive material, and can pick up substances resulting from the presence of animals or from human
activity:
microbial contaminants, such as viruses and bacteria, that may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife,
inorganic contaminants, such as salts and metals, which can be naturally occurring or result from urban storm water runoff, industrial, or domestic wastewater discharges, oil and gas
production, mining, or farming,
pesticides and herbicides, which may come from a variety of sources such as agriculture, urban storm water runoff, and residential uses,
organic chemical contaminants, including synthetic and volatile organic chemicals, which are by-products of industrial processes and petroleum production, and can also come from gas
stations, urban storm water runoff, and septic systems,
radioactive contaminants, which can be naturally occurring or be the result of oil and gas production and mining activities.
In order to ensure that tap water is safe to drink, EPA prescribes regulations that limit the amount of certain contaminants in water provided by public water systems.Food and Drug Administration
(FDA) regulations establish limits for contaminants in bottled water which must provide the same protection for public health.
Customers and the public can get involved by doing their part to conserve water and comply with all cross-connection regulations. They can also help educate others.
Your water is treated in a "treatment train" (a series of processes applied in a sequence) that includes coagulation, flocculation, sedimentation, filtration, and disinfection. Coagulation
removes dirt and other particles suspended in the source water by adding chemicals (coagulants) to form tiny sticky particles called "floc," which attract the dirt particles.Flocculation
(the formation of larger flocs from smaller flocs) is achieved using gentle, constant mixing.The heavy particles settle naturally out of the water in a sedimentation basin.The clear
water then moves to the filtration process where the water passes through sand, gravel, charcoal or other filters that remove even smaller particles. A small amount of chlorine or other
disinfection method is used to kill bacteria and other microorganisms (viruses, cysts, etc.) that may be in the water. The treated water is then stored and distributed to homes and businesses
in the community.
Water Conservation Tips
Did you know that the average U.S. household uses approximately 400 gallons of water per day or 100 gallons per person per day?Luckily, there are many low-cost and no-cost ways to conserve
water.Small changes can make a big difference – try one today and soon it will become second nature.Take short showers - a 5 minute shower uses 4 to 5 gallons of water compared to up
to 50 gallons for a bath.Shut off water while brushing your teeth, washing your hair and shaving and save up to 500 gallons a month.Use a water-efficient showerhead.They're inexpensive,
easy to install, and can save you up to 750 gallons a month.Run your clothes washer and dishwasher only when they are full.You can save up to 1,000 gallons a month.Water plants only
when necessary.Fix leaky toilets and faucets.Faucet washers are inexpensive and take only a few minutes to replace.To check your toilet for a leak, place a few drops of food coloring
in the tank and wait.If it seeps into the toilet bowl without flushing, you have a leak.Fixing it or replacing it with a new, more efficient model can save up to 1,000 gallons a month.Adjust
sprinklers so only your lawn is watered.Apply water only as fast as the soil can absorb it and during the cooler parts of the day to reduce evaporation.Teach your kids about water conservation
to ensure a future generation that uses water wisely.Make it a family effort to reduce next month's water bill!Visit www.epa.gov/watersense for more information.Cross Connection Control
Survey
The purpose of this survey is to determine whether a cross-connection may exist at your home or business.A cross connection is an unprotected or improper connection to a public water
distribution system that may cause contamination or pollution to enter the system. We are responsible for enforcing cross-connection control regulations and insuring that no contaminants
can, under any flow conditions, enter the distribution system. If you have any of the devices listed below please contact us so that we can discuss the issue, and if needed, survey your
connection and assist you in isolating it if that is necessary.
Boiler/ Radiant heater (water heaters not included)
Underground lawn sprinkler system
Pool or hot tub (whirlpool tubs not included)
Additional source(s) of water on the property
Decorative pond

Source Water Protection Tips

Protection of drinking water is everyone’s responsibility. You can help protect your community’s drinking water source in several ways:Eliminate excess use of lawn and garden fertilizers
and pesticides – they contain hazardous chemicals that can reach your drinking water source.Pick up after your pets.If you have your own septic system, properly maintain your system
to reduce leaching to water sources or consider connecting to a public sanitary sewer system.Dispose of chemicals properly; take used motor oil to a recycling center.Volunteer in your
community.Find a watershed or wellhead protection organization in your community and volunteer to help.If there are no active groups, consider starting one.Use EPA’s Adopt Your Watershed
to locate groups in your community, or visit the Watershed Information Network’s How to Start a Watershed Team.Organize a storm drain stenciling project with your local government or
water supplier.Stencil a message next to the street drain reminding people “Dump No Waste - Drains to River” or “Protect Your Water.”Produce and distribute a flyer for households to
remind residents that storm drains dump directly into your local water body.Additional Information for NitrateNitrate in drinking water at levels above 10 ppm is a health risk for infants
of less than six months of age. High nitrate levels in drinking water can cause blue baby syndrome. Nitrate levels may rise quickly for short periods of time because of rainfall or agricultural
activity. If you are caring for an infant, you should ask for advice from your health care providerAdditional Information for Lead
If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and components
associated with service lines and home plumbing. Maeser Water Improvement District is responsible for providing high quality drinking water, but cannot control the variety of materials
used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before
using water for drinking or cooking. If you are concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and
steps you can take to minimize exposure is available from the Safe Drinking Water Hotline or at www.epa.gov/safewater/lead.
Water Quality Data Table
In order to ensure that tap water is safe to drink, EPA prescribes regulations which limit the amount of contaminants in water provided by public water systems. EPA requires monitoring
of over 80 drinking water contaminants. Those contaminants listed in the table below are the only contaminants detected in your drinking water.
All sources of drinking water contain some naturally occurring contaminants. At low levels, these substances are generally not harmful in our drinking water. Removing all contaminants
would be extremely expensive, and in most cases, would not provide increased protection of public health. A few naturally occurring minerals may actually improve the taste of drinking
water and have nutritional value at low levels.
Unless otherwise noted, the data presented in this table is from testing done in the calendar year of the report. The EPA or the State requires us to monitor for certain contaminants
less than once per year because the concentrations of these contaminants do not vary significantly from year to year, or the system is not considered vulnerable to this type of contamination.
As such, some of our data, though representative, may be more than one year old. In this table you will find terms and abbreviations that might not be familiar to you. To help you better
understand these terms, we have provided the definitions below the table.

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.
Important Drinking Water Definitions
Term
Definition
MCLG
Maximum Contaminant Level Goal: 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.
MCL
Maximum Contaminant Level: 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.
TT
Treatment Technique: A required process intended to reduce the level of a contaminant in drinking water.
AL
Action Level: The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.
Variances and Exemptions
State or EPA permission not to meet an MCL or a treatment technique under certain conditions.
MRDLG
Maximum residual disinfection level goal. The level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of the
use of disinfectants to control microbial contaminants.
MRDL
Maximum residual disinfectant level. The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control
of microbial contaminants.
MNR
Monitored Not Regulated
MPL
State Assigned Maximum Permissible LevelThe following constituents are regulated more closely, Arsenic, Lead, Nitrate, Radon and Cryptosporidium. Notice of any detection is required.
EPA requires monitoring of over 80 drinking water contaminants. Those contaminants listed in the table above are the only contaminants detected in your drinking water.As you can see
by the table, our system had no violations. We’re proud that your drinking water meets or exceeds all Federal and State requirements.
