Annual Drinking Water Quality Report 2020North Logan CityWe'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 and source water sources.Our water sources are TP004 Intake, Water Canyon Springs, 1900 N 50 W Well, Green Canyon Well 1, Beef Hollow Well, Green
Canyon Well 2, Green Canyon Well 3 and Green Canyon Well 4. The Drinking Water Source Protection Plan for North Logan City 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 lowlevel of susceptibility from
potential contamination. 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 Zac Root at 435-752-1310. 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. Please contact Zac Root for more information on our meetings.North Logan Cityroutinely 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.Parts per quadrillion (ppq) or Picograms per liter (picograms/l) - one part per quadrillion corresponds to one minute in 2,000,000,000 years
or one penny in $10,000,000,000,000.Picocuries per liter (pCi/L) - picocuries per liter is a measure of the radioactivity in water.Millirems per year (mrem/yr) - measure of radiation
absorbed by the body.Million Fibers per Liter (MFL) - million fibers per liter is a measure of the presence of asbestos fibers that are longer than 10 micrometers.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.Maximum Residual Disinfectant Level (MRDL) - 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. Maximum Residual Disinfectant
Level Goal (MRDLG) - 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. Date- Because of required sampling time frames i.e. yearly, 3 years, 4 years and 6 years, sampling dates may seem outdated.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.

Discharge from rubber and chemical factoriesIf 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. North Logan City 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.We periodically
monitor for Nitrate in the water supply to meet all regulatory requirements. In 2020 we failed to take the required samples. Testing for Nitrate is used to ensure that the public is
provided with safe drinking water. This violation does not necessarily pose a health risk. We have reviewed why we failed to take the required samples 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.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 North Logan City 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.
