Annual Drinking Water Quality Report
Green Hills Country Estates Water & Sewer
Improvement District 2023

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 goal is to provide you with a safe and dependable supply of drinking water. Our water sources
have been determined to be from groundwater sources. Our water source comes from WS001-
Kelley Well and WS002-Maple Well.

The Drinking Water Source Protection Plan for Green Hills Country Estates 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 are located in remote and
protected areas and have a low level of susceptibility to potential contamination. Please contact
us if you have questions or concerns about the 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 an 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.

If you have any questions about this report or concerning your water utility, please reply by email
at [e-mail] or Contact Steven Benjamin at [e-mail] or 801-
791-7667. 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 board meetings. They are typically held
the third Monday of each month.

Green Hills Country Estates routinely monitors for contaminants 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, 2023. All drinking water, including
bottled drinking water, may be reasonably expected to contain at least small amounts of some
contaminants. It's important to remember that the presence of these contaminants 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 contaminants
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.
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.
Date- Because of required sampling time frames i.e. yearly, 3 years, 4 years and 6 years,
sampling dates may seem out-dated.

Synthetic Organic Contaminants including Pesticides and Herbicides

Results from the 11/2019 samples for Pesticides and Herbicides were all ND (non-Detects)

Semi-Volatile and Volatile Organic Contaminants:

Results from the 11/2019 Samples for Semi-volatile and volatile organic compounds were ND (Non-Detects)

Because of the high level of turbidity from the Maple Well (WS002), there is an increased
chance that the water may contain disease-causing organisms. Turbidity results for 2023
range from: 5.3 NTU to 73 NTU with 12 of the 12 samples exceeding the MCL of 5.0 NTU.
During 2023, one of the twelve Bacteria samples taken from WS002 (Maple Well) was
present for Total Coliform. However, the repeat sample result was total coliform absent.

SIGNIFICANT PHYSICAL DEFICIENCY (SIG) .
The water system is operating under a Compliance Agreement/Executive Order (CA/EO)
for turbidity, manganese, iron and gross alpha exceedances from the Utah Department of
Drinking Water (DDW) for the Maple Well (WS002). The CA/EO calls for treating the Maple
5
Well (WS002) for these conditions which will require the construction of a treatment plant.
The estimated completion time frame for the treatment plant is December 2026. As of the
date of this report the District has submitted treatment plant engineering design plans to
the State Department of Environmental Quality for approval. Once approval is obtained
requests for construction proposals will be released with treatment plant construction start
to begin within 2-3 months.

General disclosure: 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. Green
Hills Country Estates 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.

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 (800-
426-4791).
