2024 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 lessen 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 (800-
426-4791). The sources of drinking water (both tap water and bottled water) include 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 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 naturally 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 must
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 held 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 the
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 remind residents that storm drains dump directly into your local water body.
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.
Lead
Service Line Inventories
Hidden Hollow Water Company has completed an initial lead service line inventory. This inventory includes information on the
service line material that connects water mains to buildings/houses. This inventory can be requested by contacting the water
company.
Hidden Hollow Water Company determined that all service lines are non-lead.
Results of Lead and Copper Samples Collected That Year
Five lead samples were collected in 2022. Sampling results can be obtained by contacting the water company.

Updated Mandatory Health Effects Language
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 and removing lead pipes but cannot control the variety of materials used in plumbing
components in your home. You share the responsibility for protecting yourself and your family from the lead in your home
plumbing. You can take responsibility by identifying and removing lead materials within your home plumbing and taking steps to
reduce your family’s risk. Before drinking tap water, flush your pipes for several minutes by running your tap, taking a shower, doing
laundry or a load of dishes. You can also use a filter certified by an American National Standards Institute accredited certifier to
reduce lead in drinking water. If you are concerned about lead in your water and wish to have your water tested, contact the Hidden
Hollow Water Company. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is
available at http://www.epa.gov/safewater/lead.
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 more than a year old. In this table, you will find terms and
abbreviations that might not be familiar to you. To help you better understand 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
