Annual Drinking Water Quality ReportGreendale Water Company2020We're pleased to present to you this year's Annual Drinking Water Quality Report. This report is designed to inform you
about the quality of the water and services we deliver to you every day. Our constant goal is to provide you with a safe and dependable supply of drinking water. We want you to understand
the efforts we make to continually improve the water treatment process and protect our water resources. We are committed to ensuring the quality of your water. Our water sources have
been determined to be from groundwater sources. Our water source is Upper Buck Springs, Buck Springs, Unnamed Springs, and Chicken SpringsThe Drinking Water Source Protection Plan for
Greendale Water Company is available for your review. It contains information about source protection zones, potential contamination sources and management strategies to protect our
drinking water. Our sources have been determined to have a medium level of susceptibility from potential contamination from sources such as roads, residential areas, industrial areas,
etc. We have also developed management strategies to further protect our sources from contamination. Please contact us if you have questions or concerns about our source protection
plan.
There are many connections to our water distribution system. When connections are properly installed and maintained, the concerns are very minimal. However, unapproved and improper
piping changes or connections can adversely affect not only the availability, but also the quality of the water. A cross connection may let polluted water or even chemicals mingle into
the water supply system when not properly protected. This not only compromises the water quality but can also affect your health. So, what can you do? Do not make or allow improper
connections at your homes. Even that unprotected garden hose lying in the puddle next to the driveway is a cross connection. The unprotected lawn sprinkler system after you have fertilized
or sprayed is also a cross connection. When the cross connection is allowed to exist at your home, it will affect you and your family first. If you’d like to learn more about helping
to protect the quality of our water, call us for further information about ways you can help.This report shows our water quality and what it means to you our customer. If you have any
questions about this report or concerning your water utility, please contact Chris Collett at 435-790-7045.We want our valued customers to be informed about their water utility. If you
want to learn more, please attend any of our regularly scheduled meetings. They are held in March and October. Contact the office for specific dates and times.Greendale Water Company
routinely monitors for constituents in our drinking water in accordance with the Federal and Utah State laws. The following table shows the results of our monitoring for the period of
January 1st to December 31st, 2020. All drinking water, including bottled drinking water, may be reasonably expected to contain at least small amounts of some constituents. It's important
to remember that the presence of these constituents does not necessarily pose a health risk. In the following table you will find many terms and abbreviations you might not be familiar
with. To help you better understand these terms we've provided the following definitions:Non-Detects (ND) - laboratory analysis indicates that 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. Parts per trillion (ppt) or Nanograms per liter (nanograms/l) - one part per
trillion corresponds to one minute in 2,000,000 years, or a single penny in $10,000,000,000.Picocuries per liter (pCi/L) - picocuries per liter is a measure of the radioactivity in water.Nephelometric
Turbidity Unit (NTU) - nephelometric turbidity unit is a measure of the clarity of water. Turbidity in excess of 5 NTU is just noticeable to the average person.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 treatment technique is a required
process intended to reduce the level of a contaminant in drinking water.Maximum Contaminant Level (MCL) - The “Maximum Allowed” (MCL) 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.Date- Because of required sampling time frames i.e. yearly, 3 years,
4 years and 6 years, sampling dates may seem out-dated.

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. Greendale Water Company 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 at 1-800-426-4791 or at http://www.epa.gov/safewater/lead.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. We have learned through our monitoring and testing that some constituents
have been detected. The EPA has determined that your water IS SAFE at these levels. 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 1-800-426-4791.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 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 [phone]. We at Greendale Water Company 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.
