Annual Drinking Water Quality Report
Mountain Green Water Association
2020

We'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 source has been determined to be from groundwater which comes from the Mountain Green
Water Association well, system No. 15015.

SOURCE PROTECTION PLAN
The Drinking Water Source Protection Plan for Mountain Green Water Association 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 low level of susceptibility from potential contamination from sources such as road, homes, City Park, and tightly
controlled sewer lines. 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.

CROSS CONNECTION CONTROL
There are many (19) 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.

I'm pleased to report that our drinking water meets federal and state requirements.

QUESTIONS
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 William Weaver at 801-876-3374 or Rick Poll at 801-876-3059.

PLEASE ATTEND
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 annually, usually on the first Wednesday of March each year.

Mountain Green Water Association 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.

CONSTITUENT TABLE DEFINITIONS
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 (pap) 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 (pot) 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 (pap) 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 (phi/L) - picocuries per liter is a measure of the radioactivity in water.
Milligrams per year (memo/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
3
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 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.

IPS SECTION: Physical Facility Points.
There are currently no Significant Deficiencies noted or points assessed to our water system.

We do have IPS points assessed for a lack of training for a Certified Operator, a lack of storage capacity for fire suppression needs and three well
structure deficiencies. All have often been discussed in our shareholders meeting as well as corrections that are feasible. For further information
please see the annual shareholder meeting notes.

The following is the 2020 Annual Drinking Water Quality Report for the Mountain Green Water Association, number 15015.

- The sources of drinking water for our system include (pick the applicable source types for your system: 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 pickup substances resulting from the
presence of animals or from human activity.
- Contaminants that may be present in source water include:
1.Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems,
agricultural livestock operations, and wildlife.
2.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.
3.Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban storm water runoff, and
residential uses.
4.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.
5.Radioactive contaminants, which can be naturally-occurring or be the result of oil and gas production and mining
activities.
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 EPAs Safe Drinking Water Hotline at [phone].
In order to ensure that tap water is safe to drink, EPA prescribes regulations which limit the amount of certain contaminants
in water provided by public water systems. FDA regulations establish limits for contaminants in bottled water which must
provide the same protection for public health. 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 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. We 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.

ANNUAL DRINKING WATER QUALITY SUMMARY

We are happy to report that we had no new water system violations in 2020. A special thanks goes to all those who assist in collecting and
returning samples for testing.

In 2019 there were 3 Water System Violations; one for failure in MONITORING ROUTINE for Nitrate, one for a FOLLOW-UP or ROUTINE
TAP M/R (LCR) violation for Lead and Copper, and one for this report (CCR) was not received on time. All were cleared and a report is
available upon request. In 2018 we had one Water System Violations for failure to provide a TRIGGERED GROUNDWATER SOURCE
bacteriologic analysis results, E. coli (major). In 2017 we also had one Water System Violations for failure to provide a TRIGGERED
GROUNDWATER SOURCE bacteriologic analysis results, E. coli (major) and a violation for failure in MONITORING ROUTINE for Nitrate
(all were cleared).

No impurities have ever been detected through our stringent sampling efforts. 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. During the year of 2013, the State of Utah conducted an exhausting review of all water
systems in Morgan County and they reported that our area has the purest water in the entire state of Utah.

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.

The Maximum Contaminant Level (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]).
