Annual Drinking Water Quality Report-2020-Gunlock Special Service District411 N. Main St.Gunlock, Utah 84733We'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.One of our water sources is a spring located one mile above town in The Santa Clara Drainage.
Our second source is a well located within the Gunlock City limits. The Drinking Water Source Protection Plan for The Gunlock Special Service Districtis 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 low level of susceptibility from potential contamination from sources such as septic tanks & roads. 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 across connection. When the cross connectionis 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.I'm pleased to report that our drinking water meets federal and state requirements.If you
have any questions about this report or concerning your water utility, please contact Judy Leavitt at 1-435-574-2415. 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 on the first Wednesday of February, April, June, September, November and December at 7:00
p.m. in The Gunlock Town Hall.The Gunlock Special Service District 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. 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.Maximum
Contaminant Level Goal (MCLG) - The “Goal”(MCLG) 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.Date- Because of required sampling time frames i.e. yearly, 3 years, 4 years and 6 years, sampling dates may seem out-dated.Waivers (W)- Because some chemicals are not used or
stored in areas around drinking water sources, some water systems have been given waivers that exempt them from having to take certain chemical samples, these waivers are also tied to
Drinking Water Source Protection Plans.

Infants and children who drink water containing lead in excess of the action level could experience delays in their physical or mental development. Children could show slight deficits
in attention span and learning abilities. Adults who drink this water over many years could develop kidney problems or high blood pressure.
Infants and young children are typically more vulnerable to lead in drinking water than the general population. It is possible that lead levels at your home may be higher than at other
homes in the community as a result of materials used in your home’s plumbing. If you are concerned about elevated lead levels in your home’s water, you may wish to have your water tested
and flush your tap for 30 seconds to 2 minutes before using tap water. Additional information is available from the Safe Drinking Water Hotline [phone]). 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. The Gunlock Special Service 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 http://www.epa.gov/safewater/lead.Owners or operators of a public water system are required to provide
public notice for violations of drinking water standards or monitoring requirements.  FromDecember30,2019-February 6,2020 we failed to provide the public notice in regards to lead as
required. We have reviewed why we failed to provide public notice as required and will take steps to ensure that it will not happen again.All sources of drinking water are subject to
potential contamination by constituents that are naturally occurring or manmade. 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.Total Coliform: The Total Coliform Rule requires water systems
to meet a stricter limit for coliform bacteria. Coliform bacteria are usually harmless, but their presence in water can be an indication of disease-causing bacteria. When coliform bacteria
are found, special follow-up tests are done to determine if harmful bacteria are present in the water supply. If this limit is exceeded, the water supplier must notify the public by
newspaper, television or radio. To comply with the stricter regulation, we have increased the average amount of chlorine in the distribution system.Nitrates: As a precaution we always
notify physicians and health care providers in this area if there is ever a higher than normal level of nitrates in the water supply. Lead: Lead in drinking water is rarely the sole
cause of lead poisoning, but it can add to a person's total lead exposure. All potential sources of lead in the household should be identified and removed, replaced or reduced.Some people
may be more vulnerable to contaminants in drinking water than the general population. Immunocompromised 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
from their health care providers about drinking water. 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 The Gunlock Special Service Districtwork 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.
