Can You Drink Tap Water in Queen Creek?

Yes, Queen Creek's tap water is generally considered safe to drink as Queen Creek 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, Queen Creek's water utility, Town of Queen Creek, had 5 non-health-based violations of the Safe Drinking Water Act. For more details on the violations, please see our violation history section below. The last violation for Queen Creek was resolved on Dec. 31, 2019. This assessment is based on the Town of Queen Creek 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 Queen Creek Tap Water

The most recent publicly available numbers for measured contaminant levels in Queen Creek 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 Queen Creek's water quality reports, or getting your home's tap water tested to see if you should be filtering your water.

Queen Creek Tap Water Safe Drinking Water Act Violation History - Prior 10 Years

Below is a ten year history of violations for the water system named Town of Queen Creek for Queen Creek in Arizona. For more details please see the "What do these Violations Mean?" section below.

From Oct. 1, 2019 to Dec. 31, 2019, Queen Creek had 5 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, Combined Uranium, Combined Radium (-226 and -228), Radium-228, Radium-226.

From June 1, 2017 to Aug. 31, 2017, Queen Creek had 2 non-health based Safe Drinking Water Act violations with the violation category being Monitoring and Reporting, more specifically, the violation code was Monitoring and Reporting (DBP) which falls into the Disinfectants and Disinfection Byproducts Rule rule code group, and the Stage 2 Disinfectants and Disinfection Byproducts Rule rule code family for the following contaminant codes: TTHM, Total Haloacetic Acids (HAA5).

Is there Lead in Queen Creek Water?

Based on the EPA’s ECHO Database, 90% of the samples taken from the Queen Creek water system, Town of Queen Creek, between sample start date and sample end date, were at or below, 0.00225 mg/L of lead in Queen Creek water. This is 15.0% of the 0.015 mg/L action level. This means 10% of the samples taken from Queen Creek contained more lead.

While Queen Creek water testing may have found 0.00225 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 Queen Creek 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 - Williams AFB - near Queen Creek 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 Queen Creek 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.

Queen Creek 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 Queen Creek's Water. If you would like to see the original version of the report, please click here.


Water Quality Report


Where Our Water Comes From

The Town of Queen Creek’s drinking water comes from groundwater sources. Groundwater is pumped from a combination of the 22 active drinking water wells located throughout the water distribution system. Water is either pumped directly into the distribution system or pumped to fill a water storage tank for future use. A small amount of chlorine disinfection is applied at entry points to the distribution system in order to maintain federal drinking water standards.


Our Commitment to Service

The Town of Queen Creek Water Division is proud to present the 2020 Annual Water Quality Report demonstrating our exceptional water quality. Through the challenges brought by the COVID-19 pandemic, we remain dedicated to meeting the challenges of new regulations, source water protection, water conservation, and community outreach and education while continuing to serve the needs of our community. Thank you for allowing us the opportunity to serve you and your family.

The Water Division ended 2020 with over 30,000 active connections, attributed to the remarkable new single-family home and commercial growth. We expect continued growth, and with the acquisition of the Diversified Water System will serve an estimated population of approximately 95,000 by end of 2021.

The Water Division continues to focus on system integrity and reliability through infrastructure lifespan. Nearly 15 miles of new waterlines have been designed and approximately 20 miles installed, allowing the water system to operate more efficiently. Construction began on the Barney Farms three million gallon reservoir, to be completed and in service by the end of 2021. Construction was completed on the Church Farms East three million gallon reservoir.

Two wells were rehabilitated and added to our water sources. Two wells were purchased and developed with intent to be online by end of 2021. The water service area was extended to the south with the purchase and merger of the Diversified Water System, adding two active wells and three expected to be completed by end of 2021. We continue to aggressively pursue our meter testing and replacement program, which helps the Water Division ensure that water meters measure accurately, minimizing water loss.

Our geographic information systems and technology staff continue to develop efficiency improvements through technological changes, allowing staffing to access information remotely and enabling faster responses, work order completions and emergency mitigation. Improvements are continually evaluated to allow customers more access to billing and scheduling.

The Covid-19 pandemic challenged delivering our water conservation vision in-person, technology and a partnership with the City of Chandler came to the rescue and we delivered 11 virtual water conservation workshops. With our educational partnerships we provided our water conservation message through educational videos to over 3,000 students in our water service area.

We excitingly embrace the growth the Town of Queen Creek is experiencing. The Water Division remains dedicated to providing reliable high quality water. We greatly appreciate the partnership we have cultivated with the community and are honored to serve you in the future.

Paul Gardner, Utilities Director





Substances That Could be in Water

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. Contaminants that may be present in source water include:

Microbial contaminants, such as viruses and bacteria, which 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 byproducts of industrial processes and petroleum production, and can also come from gas stations, urban storm water runoff, and septic systems.

Radioactive contaminants, which can be naturally occurring or be the result of oil and gas production and mining activities.

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 online at or by calling the EPA’s Safe Drinking Water Hotline at (800) 426-4791.

Count on Us

Delivering high-quality drinking water to our customers involves far more than just pushing water through pipes. Because tap water is highly regulated by state and federal laws, water system operators must be licensed and are required to commit to long- term, on-the-job training before becoming fully qualified.

Our licensed water professionals are knowledgeable on a wide range of subjects, including mathematics, biology, chemistry, and physics.

Some of the tasks they complete on a regular basis include:

  • Operating and maintaining equipment to produce and store water.
  • Monitoring and inspecting machinery, meters, gauges, and operating conditions.
  • Conducting tests and inspections on water and evaluating the results.
  • Maintaining optimal water chemistry.
  • Applying data to formulas that determine treatment requirements, flow levels, and concentration levels.
  • Documenting and reporting test results and system operations to regulatory agencies.
  • Serving our community through customer support, education, and outreach.

So, the next time you turn on your faucet, think of the skilled professionals who stand behind every drop.





Water Quality

To ensure that tap water is safe to drink, the EPA prescribes regulations which limit the amount of certain contaminants in water provided by public water systems. FDA regulations establish limits for contaminants in bottled water which must provide the same protection for public health. Some people may be more vulnerable to contaminants in drinking water than the general population.

The Water Division continues to take hundreds of water samples to determine the presence of microbiological and various contaminants in the system. Additionally, the Water Division participates in the Arizona Department of Environmental Quality Monitoring Assistance Program (MAP) to perform regular sampling and testing of all system wells for radioactive, inorganic, volatile organic, and synthetic organic contaminants. Efforts to sample and test our water has documented that the Town of Queen Creek water has exceeded all health standards. The table below shows only those contaminants that were detected in the water, many more were tested with no measurable amounts detected. Although all the substances listed here are under the Maximum Contaminant Level (MCL), we feel it is important

that you know exactly what was detected and how much of the substance was present in the water.

Source Water Assessment

In 2002, the Arizona Department of Environmental Quality (ADEQ) completed a source water assessment for six groundwater wells used by the Queen Creek Water Company, now known as the Town of Queen Creek Water Division. The assessment reviewed adjacent land uses that could pose risks to water sources. These risks include, but are not limited to, gas stations, landfills, dry cleaners, agricultural fields, wastewater treatment plants, and mining activities. Once ADEQ identified

the adjacent land uses, the source waters were ranked according to their potential to become contaminated. The result of the assessment for the six wells was low risk from adjacent land use and low risk to source water. For more information or to request a copy of the source water assessment, please contact Nicole Petker at (480) 358-3459 or email

IMPORTANT Health Information

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 for infections. These people should seek advice from their health care provider about drinking water. EPA/CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline at (800) 426-4791.

While your drinking water meets EPA standards for arsenic, it does contain low levels of arsenic. EPA’s standard balances the current understanding of 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.

Nitrate in drinking water at levels above 10 ppm is a health risk for infants of less than six (6) months of age. High nitrate levels in drinking water can cause “blue baby syndrome.” Nitrate levels may rise quickly for short periods of time because of rainfall or agricultural activity. If you are caring for an infant, you should ask advice from your health care provider. Visit for additional information.

Lead in Home Plumbing

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. The Town of Queen Creek is responsible for providing high-quality drinking water, but we 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 before using water for drinking or cooking. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline at

Benefits of Chlorination

Disinfection, a chemical process used to control disease-causing microorganisms by killing or inactivating them, is unquestionably the most important step in drinking water treatment. By far the most common method of disinfection in North America is chlorination. Before communities began routinely treating drinking water with chlorine (starting with Chicago and Jersey City in 1908), cholera, typhoid fever, dysentery, and hepatitis A killed thousands of U.S. residents annually. Drinking water chlorination and filtration have helped to virtually eliminate these diseases in the U.S. Significant strides in public health are directly linked to the adoption of drinking water chlorination. In fact, the filtration of drinking water plus the use of chlorine is probably the most significant public health advancement in human history.


Potent Germicide Reduction in the level of many disease-causing microorganisms in drinking water to almost immeasurable levels.

Taste and Odor Reduction of many disagreeable tastes and odors like foul-smelling algae secretions, sulfides, and odors from decaying vegetation.

Biological Growth Elimination of slime bacteria, molds, and algae that commonly grow in water supply reservoirs, on the walls of water mains, and in storage tanks.

Chemical Removal of hydrogen sulfide (which has a rotten egg odor), ammonia, and other nitrogenous compounds that have unpleasant tastes and hinder disinfection. It also helps to remove iron and manganese from raw water.
