Home My WebLink AboutDDW-2024-009408 1 2023 Annual Drinking Water Quality Report Boundary Springs Water Company We’re very pleased to provide you with this year's Annual Water Quality Report. We want to keep you informed about the excellent water and services we have delivered to you over the past year. Our goal is and always has been, to provide to you a safe and dependable supply of drinking water. WATER SOURCES Your water source is from the Lower Boundary Spring located in Mill Creek Canyon. This spring produces about 700 gallons per minute of water. SOURCE PROTECTION Boundary Springs Water Co. has a Drinking Water Source Protection Plan that is available for review. It contains information about source protection zones, potential contamination sources, and management strategies to protect our drinking water. The Lower Boundary Spring has been determined to have a low susceptibility level to potential contamination events. The only potential contamination source that could affect the spring is the road. We have also developed management strategies to further protect our sources from contamination. If you have any questions or concerns regarding source protection, please contact Larry Hall with Aqua Environmental Services at 801-209- 6382. QUESTIONS The water system is currently contract operated by Aqua Environmental Services Inc (AES). If you have any questions about this report or concerning your water utility, please contact Larry Hall of Aqua Environmental Services Inc at 801-209-6382. We want our valued customers informed about their water utility. If you want to learn more, please attend any of Boundary Springs regularly scheduled meetings. For information on upcoming meeting locations, dates, and times please contact Cary Hunter at 801- 505-3380, Scott Benson at 801-824- 5784, Rick Diehl at 801-557-5666, or John English at 801-272-6606. YOU CAN PREVENT BACK FLOW There are many connections to our water distribution system. When connections are properly installed and maintained, the risks 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 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. 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. 2 MONITORING PERIOD AES routinely monitors for constituents in our drinking water in accordance with the Federal and State laws. The following table shows the results of our monitoring through December 31st, 2023. Some of the data in the table is prior to the 2023 calendar year because different testing schedules are required for different chemicals. 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. 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 (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. Parts per quadrillion (ppq) 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 (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) - (mandatory language) A treatment technique is a required process intended to reduce the level of a contaminant in drinking water. 3 Maximum Contaminant Level (MCL) - (mandatory language) 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. 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.

Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. Boundary Springs Water Co. 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. TEST SUMMARY As you can see by the above tables, our system had no violations of any contaminants, and we are happy to report 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. “I DRINK BOTTLED WATER BECAUSE IT’S SAFER” All sources of drinking water are subject to potential contamination by constituents that are naturally occurring or are man-made. Those constituents can be microbes, organic or inorganic 9 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. WHAT ABOUT FLOURIDE? Our water contains very little natural Fluoride and we do not currently add any Fluoride to the water. WHAT ABOUT HOME TREATMENT? As can be seen from this report, your water is safe from your tap. If you decide to install a treatment device on your service, you must take the responsibility for the maintenance of it. It is possible to make your water unsafe by not taking proper care of your personal treatment devices. Our water is hard and you may want to install a water softener. Water is usually softened by ion exchange systems. Sodium and potassium exchange systems are the only methods shown to work effectively. Magnetic systems have not proven to be effective. SPECIAL HEALTH ALERT 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). WHAT DETERMINES THE MCL LEVEL? Maximum Contaminant Levels or 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. Thank you for allowing us to continue providing you with clean quality water. We are pleased to keep you informed and educated on all water matters within our service area. We continue to present you with this report every year. Please call if you have any questions or concerns. Prepared By:
