Subject: Rockville Pipeline Company Consumer Confidence Report Customer Notification
Dear Mr. Davis:
Enclosed is the Rockville Pipeline Company Consumer Confidence Report which was also emailed to acsmith@utah.gov on January 20, 2025. It contains the water quality information for our
water system for the calendar year 2024.
We are mailing this report to our customers. We have also made copies of the report available at our office and on our web page.
If you have any questions, please contact me at 435-705-5060.
Sincerely,
Robert Snyder, President
Rockville Pipeline Company
Annual Drinking Water Quality Report
Rockville Pipeline
2024
We are 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. Our water sources are Rimrock Spring andWells 3,4,5. Our wells draw from the Shinarump aquifer.
Rockville Pipeline Co. has a Drinking Water Source Protection Plan that is available for review to our customers at our office. It provides more information such as potential sources
of contamination and our source protection areas.It has been determined we have a low susceptibility level to contamination. Our source is in a remote location, and there are no potential
contamination sources in the protection zones, so we consider our source to have a low susceptibility to potential contamination events.
There are many connections to our water distribution system. When connections are properly installed and maintained, the concerns are 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 we 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.
If you have any questions about this report or concerning your water utility, please contactRobert Snyder, (435) 705-5060, from 9 am to 4 pm. 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 on the first Tuesday of January, April, July, & October
at 10 AM, Call (435) 705-5060 for an agenda.The meeting place is the Rockville Pipeline office.
Rockville Pipelineroutinely 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,2024. All drinking water, including bottled drinking water, may be reasonably expected to contain at least small amounts of some constituents.
It is 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 have provided the following definitions:
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.
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.

Water additive used to control microbes
All sources of drinking water are subject to potential contamination by constituents that are naturally occurring or are 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.
Rockville Pipeline Company has completed the lead service line inventory and determined that all service lines are non-lead.
Here is information about radium-228/226 in the RPC drinking water system:
Test results received in 2023 show that our water source exceeded the standard, or maximum contaminant level (MCL), for combined radium 226/228 which is 5pCi/L. The average level of
combined radium 226/228 from quarterly sampling in 2024 at the well was 7pCi/L. This is not an emergency, but we wanted to make sure you are aware of what we are doing to correct this
situation.
What does this mean?
This is not an immediate risk. Certain minerals are radioactive and may emit a form of radiation known as alpha radiation. Some people who drink water containing alpha emitters in excess
of the MCL over many years may have an increased risk of getting cancer.
“The likelihood of developing cancer of genetic mutations from short-term exposure to the concentrations of radionuclides found in drinking water supplies is negligible. However, long
term exposures may result in increased risks of genetic effects and other effects such as cancer, precancerous lesions, benign tumors, and congenital effects.” (EPA Radionuclides Final
Rule, at page 76720.)
What is being done?
We are working with the Utah Division of Drinking Water to evaluate the water supply and research options to correct the problem. These options could include treating the water to remove
the radium 226/228, blending with water from other sources, or filtering to remove the radium 226/228. We will keep you informed as the evaluation progresses.
What should I do?
You do not need to use an alternative (e.g., bottled) water supply.
However, if you have specific health concerns, consult your doctor 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 (800-426-4791).
We at Rockville Pipeline work diligently 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.
