Can You Drink Tap Water in Orem?

Yes, Orem's tap water is generally considered safe to drink as Orem has no active health based violations of the Safe Drinking Water Act (SDWA) that we are aware of. Other factors such as lead piping in a home, or low levels of pollutants on immunocompromised individuals, should also be considered, however. To find more recent info we might have, you can check out our boil water notice page or the city's water provider website.

According the EPA’s ECHO database, from April 30, 2019 to June 30, 2022, Orem's water utility, Orem City Water System, had 0 violations of the Safe Drinking Water Act. For more details on the violations, please see our violation history section below. The last violation for Orem was resolved on Dec. 31, 2014. This assessment is based on the Orem City Water System water system, other water systems in the city may have different results.

While tap water that meets the EPA health guidelines generally won’t make you sick to your stomach, it can still contain regulated and unregulated contaminants present in trace amounts that could potentially cause health issues over the long-run. These trace contaminants may also impact immunocompromised and vulnerable individuals.

The EPA is reviewing if it’s current regulations around pollutant levels in tap water are strict enough, and the health dangers posed by unregulated pollutants, like PFAS.

Water Quality Report for Orem Tap Water

The most recent publicly available numbers for measured contaminant levels in Orem tap water are in its 2020 Water Quality Report. As you can see, there are levels which the EPA considers to be acceptable, but being below the maximum allowable level doesn’t necessarily mean the water is healthy.

Lead in tap water, for example, is currently allowed at up to 15ppb by the EPA, but it has set the ideal goal for lead at zero. This highlights how meeting EPA standards doesn’t necessarily mean local tap water is healthy.

EPA regulations continue to change as it evaluates the long term impacts of chemicals and updates drinking water acceptable levels. The rules around arsenic, as well as, lead and copper are currently being re-evaluated.

There are also a number of "emerging" contaminants that are not currently. For example, PFAS (Per- and polyfluoroalkyl substances), for which the EPA has issued a health advisory. PFAS are called "forever chemicals" since they tend not to break down in the environment or the human body and can accumulate over time.

We recommend looking at the contaminants present in Orem's water quality reports, or getting your home's tap water tested to see if you should be filtering your water.

Orem Tap Water Safe Drinking Water Act Violation History - Prior 10 Years

Below is a ten year history of violations for the water system named Orem City Water System for Orem in Utah. For more details please see the "What do these Violations Mean?" section below.

From April 1, 2013 to June 30, 2013, Orem had 3 non-health based Safe Drinking Water Act violations with the violation category being Monitoring and Reporting, more specifically, the violation code was Monitoring, Regular which falls into the Chemicals rule code group, and the Radionuclides rule code family for the following contaminant codes: Radium-226, Radium-228, Gross Alpha, Excl. Radon and U.

From Oct. 1, 2012 to Dec. 31, 2012, Orem had 3 non-health based Safe Drinking Water Act violations with the violation category being Monitoring and Reporting, more specifically, the violation code was Monitoring, Regular which falls into the Chemicals rule code group, and the Radionuclides rule code family for the following contaminant codes: Gross Alpha, Excl. Radon and U, Radium-226, Radium-228.

From Oct. 1, 2012 to Dec. 31, 2012, Orem had 1 non-health based Safe Drinking Water Act violation with the violation category being Monitoring and Reporting, more specifically, the violation code was Monitoring, Regular which falls into the Chemicals rule code group, and the Inorganic Chemicals rule code family for the following contaminant code: Arsenic.

From Jan. 1, 2012 to Dec. 31, 2012, Orem had 1 non-health based Safe Drinking Water Act violation with the violation category being Monitoring and Reporting, more specifically, the violation code was Monitoring, Regular which falls into the Chemicals rule code group, and the Inorganic Chemicals rule code family for the following contaminant code: Nitrate.

Is there Lead in Orem Water?

Based on the EPA’s ECHO Database, 90% of the samples taken from the Orem water system, Orem City Water System, between sample start date and sample end date, were at or below, 0.0022 mg/L of lead in Orem water. This is 14.7% of the 0.015 mg/L action level. This means 10% of the samples taken from Orem contained more lead.

While Orem water testing may have found 0.0022 mg/L of lead in its water, that does not mean your water source has the same amount. The amount of lead in water in a city can vary greatly from neighborhood to neighborhood, or even building to building. Many buildings, particularly older ones, have lead pipes or service lines which can be a source of contamination. To find out if your home has lead, we recommend getting you water tested.

No amount of lead in water is healthy, only less dangerous. As lead accumulates in our bodies over time, even exposure to relatively small amounts can have negative health effects. For more information, please check out our Lead FAQ page.

Are there PFAS in Orem Tap Water?

Currently, testing tap water for PFAS isn’t mandated on a national level. We do have a list of military bases where there have been suspected or confirmed leaks. There appears to be at least one military base - Sustained Airborne Training Facility Salt Lake City - near Orem with suspected leaks.

With many potential sources of PFAS in tap water across the US, the best information we currently have about which cities have PFAS in their water is this ewg map, which you can check to see if Orem has been evaluated for yet.

Our stance is better safe than sorry, and that it makes sense to try to purify the tap water just in case.

What do these Violations Mean?

Safe Drinking Water Act Violations categories split into two groups, health based, and non-health based. Generally, health based violations are more serious, though non-health based violations can also be cause for concern.

Health Based Violations

  1. Maximum contaminant levels (MCLs) - maximum allowed contaminant level was exceeded.
  2. Maximum residual disinfectant levels (MRDLs) - maximum allowed disinfectant level was exceeded.
  3. Other violations (Other) - the exact required process to reduce the amounts of contaminants in drinking water was not followed.

Non-Health Based Violations

  1. Monitoring and reporting violations (MR, MON) - failure to conduct the required regular monitoring of drinking water quality, and/or to submit monitoring results on time.
  2. Public notice violations (Other) - failure to immediately alert consumers if there is a serious problem with their drinking water that may pose a risk to public health.
  3. Other violations (Other) - miscellaneous violations, such as failure to issue annual consumer confidence reports or maintain required records.

Orem Water - Frequently Asked Questions

WHERE DOES MY WATER COME FROM?
Orem uses a variety of sources to provide water to its residents and customers. Approximately 60% of Orem’s water comes from surface water sources, whereas 40% comes from ground water sources. Surface water sources include the Provo River, Deer Creek Reservoir, and Jordanelle Reservoir. All of Orem’s surface water is treated (filtered and disinfected) at the Don A. Christiansen Regional Water Treatment Plant (DACRWTP), which is operated by the Central Utah Water Conservancy District (CUWCD). Orem’s ground water sources consist of nine deep wells located throughout the city. Wells pump from subterranean aquifers and provide 25% of Orem’s water. Two mountain spring sources located in Provo Canyon contribute 15% of Orem’s water. Ground water (wells and springs) is pure enough to not require treatment. All of Orem’s water, whether from surface or ground water, is blended together within the distribution system. In 2020, Orem produced over 9.2 billion gallons of clean, safe drinking water to its customers. Health Care Alert The DACRWTP has tested for cryptosporidium in its source water and the results show no presence. Cryptosporidium may at times be present in its untreated sources. Cryptosporidium must be ingested to cause disease and it may be spread through means other than drinking water. Ingestion of this parasite may cause abdominal infection. Symptoms of infection include nausea, diarrhea, and abdominal cramps. Based on current knowledge, cryptosporidium does not present a health risk for the general public. Cryptosporidium has never been found in the DACRWTP’s finished (treated) water. 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 of infections. These people should seek advice about drinking water from their health care providers. More information about contaminants and potential health effects can be obtained by calling the EPA’s Safe Drinking Water Hotline at (800) 426-4791. They can provide EPA/CDC guidelines on appropriate means to lessen the risk of infection caused by cryptosporidium and other microbial contaminants. Bacteriological And Chemical Testing More than 1,460 drinking water samples were analyzed for bacteriological contamination in 2020. No bacteriological contamination was confirmed in these samples. Additional sampling was performed for disinfection byproducts, nitrates, inorganics, metals, pesticides, volatile organic compounds, radioactive materials, and other contaminants. Only trace amounts of contaminants identified in this document were detected in Orem source water. Orem drinking water meets or exceeds water quality standards set by the USEPA and the State of Utah.
WHAT ARE LEAD’S HEALTH AFFECTS?
The primary source of lead exposure for most children is lead-based paint in older homes, though lead in drinking water can add to that exposure. If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Infants and children who drink water containing lead in excess of the action level could experience delays in their physical or mental development, including behavioral problems and learning disabilities. Children six years old and under are most at risk because this is when the brain is developing. Children could show slight deficits in attention span and develop learning disabilities. Adults who drink this water over many years could develop kidney problems or high blood pressure. The current maximum contaminant level (MCL) for lead is 0.015 mg/L, and the EPA is recommending the addition of a triggered level of 0.010 mg/L. Systems above 0.010 mg/L, but below 0.015 mg/L would be required to set an annual goal for conducting replacements of city-owned service lines and conduct outreach to encourage residents to replace their plumbing that may be contributing to lead. Lead in tap water is primarily from materials and components associated with service lines and home plumbing. The most important time to flush your internal plumbing is after long periods of no use, such as first thing in the morning, after work, or upon returning from vacation. Running cold water from the faucets for drinking can improve water quality by drawing fresh water into the home, particularly after long periods of time when water has not been used. Typically, 30 seconds to 2 minutes (or until you feel the temperature of the water change) is sufficient. Use cold water for cooking and drinking. When purchasing replacement plumbing products, make sure the products have been tested and certified to “lead-free” standards. Additional information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available at the USEPA Safe Drinking Water Hotline at (800) 426-4791 or https://www.epa.gov/ground-water-and-drinking-water/ basic-information-about-lead-drinking-water.

Orem Water Quality Report (Consumer Confidence Report)

The EPA mandates that towns and cities consistently monitor and test their tap water. They must report their findings in an annual Consumer Confidence Report. Below is the most recent water quality report from Orem's Water. If you would like to see the original version of the report, please click here.

City of Orem

2020 Consumer Confidence Report

This Water Quality Report provides information about the excellent water the City of Orem delivers to you every day. Our number one goal is to provide you and your family a safe and dependable supply of drinking water. Employees always strive to deliver a quality product and protect the city’s precious water resources. To ensure the safety of your water, water professionals routinely monitor for water quality according to federal and state laws, rules, and regulations. This water report is based on the results from the most recent testing done in accordance with these laws and regulations.

Ensuring Safe Tap 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 the water poses a health risk. National Primary Drinking Water Regulations (NPDWRs or primary standards) are legally enforceable standards that apply to public water systems. Primary standards protect public health by limiting the amount of certain contaminants in water provided by public water systems. Orem treats its water according to these regulations. The Food and Drug Administration (FDA) has established limits for contaminants in bottled water to protect public health. Some people may be more vulnerable to contaminants in drinking water than the general population.

Safe Drinking Water

In 1974, the Federal Safe Drinking Water Act (SDWA) was passed to establish standards for public drinking water. The law was amended in 1986 and again in 1996 and requires many actions to protect drinking water. The United States Environmental Protection Agency (USEPA) and the Utah State Department of Health set water quality standards that require water suppliers to monitor and treat potentially harmful contaminants. Drinking water standards specifically relate to your health and are generally based on health affects which may occur if a person were to drink two liters (about two quarts) of water each day for seventy years.

Where Does My Water Come From?

Orem uses a variety of sources to provide water to its residents and customers. Approximately 60% of Orem’s water comes from surface water sources, whereas 40% comes from ground water sources. Surface water sources include the Provo River, Deer Creek Reservoir, and Jordanelle Reservoir. All of Orem’s surface water is treated (filtered and disinfected) at the Don A.

These people should seek advice about drinking water from their health care providers. More information about contaminants and potential health effects can be obtained by calling the EPA’s Safe Drinking Water Hotline at (800) 426-4791. They can provide EPA/CDC guidelines on appropriate means to lessen the risk of infection caused by cryptosporidium and other microbial contaminants.

Bacteriological And Chemical Testing

More than 1,460 drinking water samples were analyzed for bacteriological contamination in 2020. No bacteriological contamination was confirmed in these samples. Additional sampling was performed for disinfection byproducts, nitrates, inorganics, metals, pesticides, volatile organic compounds, radioactive materials, and other contaminants. Only trace amounts of contaminants identified in this document were detected in Orem source water. Orem drinking water meets or exceeds water quality standards set by the USEPA and the State of Utah.

Source Water Contaminants

The sources of drinking water for the City of Orem include rivers, lakes, streams, reservoirs, wells, and springs. As water travels over the surface of the land or through the ground, it dissolves naturally occurring minerals and, in some cases, radioactive materials. It can also dissolve or pickup substances from human or animal activity. The following contaminants may be present in source water before it is treated:

  • Microbial contaminants, such as viruses and bacteria, come from sewage treatment facilities, septic systems, agricultural livestock operations, and wildlife.
  • Inorganic contaminants, such as salts and metals, are naturally occurring or can result from urban storm water runoff, industrial or domestic wastewater discharges, oil and gas production, mining, and farming.
  • Pesticides and herbicides come from a variety of sources such as agricultural and residential uses.
  • Radioactive contaminants are naturally occurring in water and soil.
  • Organic chemical contaminants, including synthetic and volatile organic chemicals, are byproducts of industrial processes and petroleum production. These contaminants can also come from gas stations, urban storm water runoff, and septic systems.

Variances and Exemptions

Due to the high quality of Orem’s water, the State of Utah and USEPA have granted the City of Orem and the Don A. Christiansen Regional Water Treatment Plant exemptions that allow for a reduction in conducting some chemical testing less frequently.

Water Quality Data (Primary Standards)

The following tables list all detected contaminants in Orem’s drinking water system during the period between 2016 to 2020. The presence of these contaminants does not necessarily indicate the water poses a health risk. A list of definitions and abbreviations is found below for reference. The interval for testing monitoring schedule is determined by the type of contaminates, source, and quality of the water. Monitoring is required at least every 9 years for surface water and every 3 years for ground water.

What Are Lead’s Health Affects?

The primary source of lead exposure for most children is lead-based paint in older homes, though lead in drinking water can add to that exposure. If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Infants and children who drink water containing lead in excess of the action level could experience delays in their physical or mental development, including behavioral problems and learning disabilities. Children six years old and under are most at risk because this is when the brain is developing. Children could show slight deficits in attention span and develop learning disabilities. Adults who drink this water over many years could develop kidney problems or high blood pressure. The current maximum contaminant level (MCL) for lead is 0.015 mg/L, and the EPA is recommending the addition of a triggered level of 0.010 mg/L. Systems above 0.010 mg/L, but below 0.015 mg/L would be required to set an annual goal for conducting replacements of city-owned service lines and conduct outreach to encourage residents to replace their plumbing that may be contributing to lead.

How Can I Reduce My Family’s Exposure To Lead In Tap Water?

Lead in tap water is primarily from materials and components associated with service lines and home plumbing. The most important time to flush your internal plumbing is after long periods of no use, such as first thing in the morning, after work, or upon returning from vacation. Running cold water from the faucets for drinking can improve water quality by drawing fresh water into the home, particularly after long periods of time when water has not been used. Typically, 30 seconds to 2 minutes (or until you feel the temperature of the water change) is sufficient. Use cold water for cooking and drinking. When purchasing replacement plumbing products, make sure the products have been tested and certified to “lead-free” standards. Additional information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available at the USEPA Safe Drinking Water Hotline at (800) 426-4791 or https://www.epa.gov/ground-water-and-drinking-water/ basic-information-about-lead-drinking-water.

Citizen Participation

If you would like to participate in decisions that affect drinking water quality in the City of Orem, you are invited to attend an Orem City Council meeting. These public meetings are typically held on the 2nd and 4th Tuesday of each month at 6:00 p.m. in the City Council Chambers at the Orem City Center located at 56 North State Street in Orem, Utah. More information about contaminants and potential health affects can be obtained by visiting www.epa.gov/safewater/ or calling the USEPA Safe Drinking Water Hotline at (800) 426-4791.

Protecting our Valuable Water Resources

Many of the homes and businesses in Orem are built within the city’s drinking water source protection zones as established in accordance with State regulations. The City of Orem obtains its drinking water from both ground water, such as wells and springs, and surface water. Much of Provo Canyon is the watershed area supplying Orem with high quality water we have come to expect. Improper usage, storage, and disposal of chemicals or other substances could potentially contaminate the ground water and surface water sources. Examples of such substances are fertilizers, pesticides, cleaning solvents, motor oil, and fuels. All residents and property owners are encouraged to use best management practices when using and storing these substances. Proper storage, mixing, spill cleanup, watering, and disposal procedures for chemicals are essential in protecting our environment. The complete Drinking Water Source Protection Plan for the City of Orem is available for review at the Orem Public Works Department,1450 West 550 North Orem, Utah, 84057, www.orem.org, or the Utah Division of Drinking Water website: https://deq.utah.gov/division-drinking-water.

The city is a member of the Provo River Watershed Council, together with state agencies, conservancy districts, municipalities, and other members of private and public organizations. Together, we work to protect this precious watershed. As part of the Provo River Watershed Council, we promote and support watershed best management practices through partnerships, collaboration, education, and water quality monitoring. These efforts help ensure high quality source water for the DACRWTP.

PRECAUTIONARY STATEMENT: All pesticides and herbicides have both benefits and risks. Benefits can be maximized and risks minimized by reading and following the product labels. Pay close attention to the directions for use and the precautionary statements. The information on labels contains both instructions and limitations. The labels are legal documents and it is a violation of both federal and state laws to use pesticides and herbicides in a manner that is inconsistent with its labeling. The applicator is legally responsible for the proper use of these products.

Pesticides and Herbicides

Though pesticides are helpful in controlling pests, and herbicides produce beautiful, healthy lawns and gardens, these products can be dangerous and have harmful affects on the environment when improperly used. When using pesticides and herbicides, you must follow label directions carefully to minimize harm to people and beneficial plants and animals. For more information on alternative pest control methods and proper application and disposal of pesticides and herbicides, contact the Utah State University Extension at (801) 851-8460.

When using pesticides and herbicides:

  • Use pesticides and herbicides only when absolutely necessary. Properly identify pests and use the proper treatment. Read and follow label directions, which is the law. Chemicals must be in their original containers and approved for use in our area.
  • Store chemicals in a cool, dry, well-ventilated location out of the sun such as a locked cabinet or room. They should be kept in their original containers and out of reach of children or animals. Keep the container tightly closed when not in use.
  • The storage areas should have an impermeable floor (such as concrete) to eliminate the risk of leaks or spills from spreading and leaching into the unprotected ground.
  • Never mix chemicals where they can enter into storm drains or ditches (e.g. streets, gutters, sidewalks, etc.). Mix on an impermeable surface so spills can be cleaned up thoroughly.
  • Never dispose of excess or unwanted chemicals by dumping them on the ground, in a ditch, gutter, or storm drain. Such practices allow the hazardous chemicals to move directly into streams and lakes where they can harm fish and wildlife. In addition, pesticides dumped down the household drain can kill beneficial organisms that help treat waste water in treatment plants or septic systems.
  • Clean up spills and properly dispose of any extra chemicals by following manufacturer’s instructions.
  • Dispose of empty containers as instructed on the label.
  • Don't over water after application.

Unregulated Contaminant Monitoring (UCMR 4)

The 1996 Safe Drinking Water Act (SDWA) amendments require the EPA to issue a new list of no more than 30 unregulated contaminants to be monitored by public water systems once every five years. The city has completed the UCMR 4 testing for 30 contaminants. The EPA uses the Unregulated Contaminant Monitoring Rule (UCMR) to collect data for contaminants that are suspected to be present in drinking water but do not have health-based standards set under the SDWA. The City is preparing to begin testing for the UCMR 5 contaminants, during the 2023 to 2025 period.

CROSS CONNECTIONS

Exactly, what is a cross connection and why should I care? A cross connection is any connection that provides a path for contamination to occur and is not protected by a backflow prevention device or assembly. Common hazards in and around your house can contaminate your drinking water as well as your neighbor’s. These hazards are known as cross connections and can result in contaminated water backflowing into your home’s drinking water supply without you even knowing. Backflow events can occur every day in all types of water systems causing people to become sick or ill. Poor water quality can result in just a few moments, but backflow prevention is very cost effective. A small backflow assembly or device prevents backflows from occurring and can save millions of dollars in remediation expenses.

Examples of cross connections include a hose-end sprayer for fertilizers or pesticides that you use in your yard, a hose forced into a drain pipe to free a plug, or a hose end left submerged in a swimming pool, laundry sink, or any other container filled with fluids. In each of these examples, it may be possible for contaminated water to be introduced into the drinking water system. To protect your water from these types of cross connections, make sure to have hose bib vacuum breakers (Figure 1) installed on each of your hose bibs. These simple devices are inexpensive and can be purchased from your local hardware store.

The City has adopted a Cross Connection Control Program that is required by federal and state agencies and designed to preserve safe drinking water once the water supply has entered the system. Cross connection control is the methods, practices, and procedures used to prevent contamination and pollution of drinking water from backflow. These controls are important and ensure that your drinking water remains safe from bacteria,

chemicals, and other substances that may enter the water system during abnormal pressure changes. The proper installation, use, and maintenance of this protection is required for backflow devices or assemblies and is outlined in Section 21-1-14 of the Orem City Code which can be accessed through the Government menu at https://www.orem.org.

2020 Sanitary Survey

All public drinking water systems are periodically inspected to assess their construction, operations, and record keeping. The inspections identify conditions that may present a sanitary or public health risk. Points are assigned for any deficiencies. State of Utah officials completed a survey of Orem's system in July 2020 and did not assign any points against Orem's water system approval rating. For more information about sanitary surveys please got to deq.utah.gov/drinking- water/sanitary-surveys.

Wise Water Use

Utah is the second driest state in the nation. Water conservation by individual citizens is an important part of making sure we'll have enough today and in the future. Here are some things we can all do to help preserve this precious resource:

  • Fix plumbing leaks.
  • Take shorter showers.
  • Replace regular shower heads with low-volume heads. Remember, a bath takes about 36 gallons of water. A shower takes about 25.
  • Be conservative with toilet flushes. Don't use the toilet for trash disposal.
  • Don't leave the water running when shaving or brushing teeth.
  • Wash full loads of laundry and dishes, not partial loads.
  • Don't rinse dishes with running tap water. Instead, rinse dishes by dipping.
  • Keep a pitcher of cold water in the refrigerator instead of running tap water until it cools.
  • Water lawn, gardens, etc. in the coolest part of the day. Deep soak weekly instead of lightly sprinkling daily. Water the plants, not concrete.
  • Use a bucket when washing cars. Don't let the hose run.

Reminder

Always take extra precautions, the water may be safe to drink when it leaves the sewage treatment plant but it may pick up pollutants during its way to your tap. We advise that you ask locals or hotel staff about the water quality. Also, note that different cities have different water mineral contents.

Sources and Resources

It looks like in Orem, the water they are serving may be pretty unsafe. I have seen some reports stating that they are not using chloramine, a perfect disinfection ingredient for drinking water. Other people have indicated that they think they are but haven’t verified it. It would seem that whoever is deciding to serve tap water in Orem needs to research the subject.

Yes, tap water is safe. However, other things are not. For instance, the city of Orem uses chlorine as a means of disinfection. In addition to using chloramine for that purpose, they use a chloroform agent to kill bacteria before the chlorine gets added to the water.

There are other areas of the country that use different methods besides chlorine, such as iodine. I’m sure you’ve heard of iodine tablets. These are widely used in other countries around the world for the same purpose. Of course, if your area doesn’t connect with a chloramine connection like the one in Orem, you probably don’t need an iodine tablet. However, these aren’t used in the United States.
