2023 Hidden Hollow Water Quality Report
Is my water safe?
We are pleased to present this year's Annual Water Quality Report (Consumer Confidence
Report) as required by the Safe Drinking Water Act (SDWA). This report is designed to provide
details about where your water comes from, what it contains, and how it compares to
standards set by regulatory agencies. This report is a snapshot of last year's water quality. We
are committed to providing you with the information because informed customers are our best
allies.
Do I need to take special precautions?
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/Centers for Disease Control (CDC) guidelines on appropriate means to le ssen the risk of
infection by Cryptosporidium and other microbial contaminants are available from the Safe
Water Drinking Hotline [phone])
Where does my water come from?
Our water source is one well known as the Hidden Hollow Well. This water source has been
determined to be from a groundwater source.
Source water assessment and its availability
A source protection plan has been developed and is available for review. It contains information
about the source protection zones, potential contamination sources and management
strategies to protect our drinking water.
Why are there contaminants in my drinking water?
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 Environmental Protection Agency's (EPA) Safe Drinking
Water Hotline [phone]). The sources of drinking water (both tap water and bottled
water) include rivers, lakes, streams, ponds, reservoirs, s prings, 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 pick up substances resulting from the presence of
animals or from human activity: microbial contaminants, such as viruses and bacteria, that may
come from sewage treatment plants, septic systems, agricultural livestock operations, and
wildlife; 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; pesticides and herbicides, which may come from a variety of
sources such as agriculture, urban storm water runoff, and residential uses; 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; and radioactive contaminants, which can be natural ly
occurring or be the result of oil and gas production and mining activities. In order to ensure that
tap water is safe to drink, EPA prescribes regulations that limit the amount of certain
contaminants in water provided by public water systems. Food and Drug Administration (FDA)
regulations establish limits for contaminants in bottled water which mus t provide the same
protection for public health.
How can I get involved?
You can contact me anytime you have a concern about your drinking water. I also suggest
attending the annual shareholders meeting that is typically hel d in March of each year.
Water Conservation Tips
Did you know that the average U.S. household uses approximately 400 gallons of water per day
or 100 gallons per person per day? Luckily. there are many low -cost and no-cost ways to
conserve water. Small changes can make a big difference - try one today and soon it will
become second nature.
• Take short showers - a 5-minute shower uses 4 to 5 gallons of water compared to up to
50 gallons for a bath.
• Shut off water while brushing your teeth, washing your hair and shaving and save up to
500 gallons a month.
• Use a water-efficient showerhead. They're inexpensive, easy to install, and can save you
up to 750 gallons a month.
• Run your clothes washer and dishwasher only when they are full. You can save up to
1,000 gallons a month.
• Water plants only when necessary.
• Fix leaky toilets and faucets. Faucet washers are inexpensive and take only a few
minutes to replace. To check your toilet for a leak, place a few drops of food coloring in
the tank and wait. If it seeps into the toilet bowl without flushing, you have a leak. Fixing
it or replacing it with a new, more efficient model can save up to 1,000 gallons a month.
• Adjust sprinklers so only your lawn is watered. Apply water only as a fast as the soil can
absorb it and during the cooler parts of the day to reduce evaporation.
• Teach your kids about water conservation to ensure a future generation that uses water
wisely. Make it a family effort to reduce next month's water bill!
• Visit www.epa.gov/watersense for more information.
Cross Connection Control Survey
The purpose of this survey is to determine whether a cross -connection may exist at your home
or business. A cross connection is an unprotected or improper connection to a public water
distribution system that may cause contamination or pollution to enter t he system. We are
responsible for enforcing cross -connection control regulations and ensuring that no
contaminants can, under any flow conditions, enter the distribution system. If you have any of
these devices listed below, please contact us so that we can discuss the issue, and if needed,
survey your connection and assist you in isolating it if that is necessary.
• Boiler/Radiant heater (water heaters not included)
• Underground lawn sprinkler system
• Pool or hot tub (whirlpool tubs not included)
• Additional source(s) of water on the property
• Watering trough
Source Water Protection Tips
Protection of drinking water is everyone's responsibility. You can help protect your
community's drinking water source in several ways:
• Eliminate excess use of lawn and garden fertilizers and pesticides - they contain
hazardous chemicals that can reach your drinking water source.
• Pick up after your pets.
• If you have a septic system, properly maintain your system to reduce leaching to water
sources.
• Dispose of chemicals properly; take used oil to a recycling center.
• Volunteer in your community. Find a watershed or wellhead protection organization in
your community and volunteer to help. If there are no active groups, consider starting
one. Use EPA's Adopt Your Watershed to locate groups in your community or visit the
Watershed Information Network's How to Start a Watershed Team.
• Organize a storm drain stenciling project with your local government or water supplier.
Stencil a message next to a street drain reminding people "Dump No Waste - Drains to
River" or "Protect Your Water." Produce and distribute a flyer for households to re mind
residents that storm drains dump directly into your local water body.
Additional Information for Lead
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. Hidden Hollow 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 h ours, you can minimize
the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using
water for drinking and cooking. If you are concerned about lead in your 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.
Additional Information for Arsenic
While your drinking water meets EPA’s standard for arsenic, it does contain low levels of
arsenic. EPA’s standard balances the current understanding of arsenic’s possible health effects
against the costs of removing arsenic from drinking water. EPA continues to research the health
effects of low levels of arsenic which is a mineral known to cause cancer in humans at high
concentrations and is linked to other health effects such as skin damage and circulatory
problems.
Water Quality Data Table
In order to ensure that tap water is safe to drink, EPA prescribes regulations which limit the
number of contaminants in water provided by public water systems. The table below lists all of
the drinking water contaminants that we detected during the 2016 calendar year. Although
many more contaminants were tested, only those substances listed below were found in your
water. All sources of drinking water contain some naturally occurring contaminants. At low
levels, these substances are generally not harmful in our drinking water. Removing all
contaminants would be extremely expensive, and in most cases, would not provide increased
protection of public health. A few naturally occurring minerals may actually improve the taste
of drinking water and have nutritional value at low levels. Unless otherwise noted, the data
presented in this table is from testing done in the calendar year of the report. The EPA or the
State of Utah requires us to monitor for certain contaminants less than once per year because
the concentrations of these contaminants do not vary significantly from year to year, or the
system is not considered vulnerable to this type of contamination. As such, some of our data, though representative, may be m ore
than a year old. In this table, you will find terms and abbreviations that might not be familiar to you. To help you better u nderstand
these terms, we have provided the definitions below the table.
To ensure the safest water possible the State has required us to monitor some contaminants not required by Federal regulation . Of
those contaminants only those listed below were found in your water.

Important Drinking Water Definitions
MCLG – Maximum Contaminant Level Goal: 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.
MCL – Maximum Contaminant Level: 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.
TT – Treatment Technique: A required process intended to reduce the level of a contaminant in
drinking water.
AL – Action Level: The concentration of a contaminant which, if exceeded, triggers treatment or
other requirements by a water system.
Variances and Exemptions – State or EPA permission not to meet an MCL or a treatment
technique under certain conditions.
MRDLG – Maximum residual disinfection level goal: 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.
MRDL – Maximum residual disinfectant level: The highest level of a disinfectant allowed in
drinking water. There is convincing evidence that addition of a disinfectant is necessary to
control of microbial contaminants.
MNR – Monitored Not Regulated
MPL – State assigned Maximum Permissible Level
