Can You Drink Tap Water in Aurora?

Yes, Aurora's tap water is generally considered safe to drink as Aurora 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, the city's water provider website, or Aurora's local Twitter account.

According the EPA’s ECHO database, from April 30, 2019 to June 30, 2022, Aurora's water utility, City of Aurora, 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 Aurora was resolved on March 31, 2016. This assessment is based on the City of Aurora 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 Aurora Tap Water

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

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

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

From Jan. 1, 2016 to March 31, 2016, Aurora 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 Aurora Water?

Based on the EPA’s ECHO Database, 90% of the samples taken from the Aurora water system, City of Aurora, between sample start date and sample end date, were at or below, 0.0013 mg/L of lead in Aurora water. This is 8.7% of the 0.015 mg/L action level. This means 10% of the samples taken from Aurora contained more lead.

While Aurora water testing may have found 0.0013 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 Aurora 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 - Buckley Annex - near Aurora 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 Aurora 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.

CITY OF AURORA, COLORADO | 2021

In Colorado, we rely heavily on snowmelt for our water supply, but from year to year, it can be difficult to predict how much will be available. That’s why we’ve developed a diverse water portfolio that allows us to access water from a variety of sources, ensuring that we will have adequate supplies to meet demand.

Our water travels from 180 miles away and our system includes the use of reservoirs, the natural river system, pipes, tunnels and pumps, all of which help us pull the water we own from the Colorado, Arkansas and South Platte river basins. That water is stored in 12 reservoirs and lakes: Aurora, Homestake, Turquoise, Twin Lakes, Spinney Mountain, Jefferson, Strontia Springs, Rampart, Quincy, Pueblo, Henry and Meredith.

IT’S GREAT WATER.

DRINK IT UP.

EPA’s Safe Drinking Water Hotline 800.426.4791

City of Aurora Water Customer Service 303.326.8645

Colorado Source Water Assessment and Protection is a state program designed to provide consumers with information about their drinking water, as well as provide opportunities for public involvement. The Colorado State Source Water Assessment Report is available by calling 303.692.2000,

or by visitingwww.Colorado.gov/cdphe/ccr.

City of Aurora | All data from January 1, 2020 to December 31, 2020, unless otherwise noted. Public Water System Identification CO0103005.

The table details the contaminants detected in Aurora’s drinking water during 2020. All are well below allowed levels. To safeguard your health, Aurora tests for approximately150 other contaminants that were not detected, and therefore are not included in the table of detected contaminants. Tests on our water are conducted in our Quality Control Laboratory, which is certified by the Colorado Department of Public Health and Environment (CDPHE). Independent laboratories conduct other tests as necessary. Each year, more than 85,000 tests are conducted. We also test for contaminants not yet regulated by the U.S. Environmental Protection Agency (EPA).

The state permits monitoring less than once per year for some contaminants because the concentrations of these contaminants do not vary significantly. Some of the data, though representative, may be more than one year old. Colorado has a statewide waiver for dioxin monitoring. Aurora has monitoring waivers for cyanide and asbestos. The waivers were granted because the CDPHE determined the Aurora water system is not vulnerable to these contaminants.

Action Level (AL): The concentration of a contaminant, which, if exceeded, triggers treatment or other requirements that a water system must follow.

Maximum Contaminant Level (MCL): The highest level of a contaminant 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 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.

Maximum Residual Disinfectant Level (MRDL): The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants. Maximum Residual Disinfectant Level Goal (MRDLG): The level of a disinfectant allowed in drinking water, 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.

Secondary Maximum Contaminant Level (SMCL): The concentration of a contaminant that is recommended, but not enforceable, in drinking water due to its effect on taste, color, odor or appearance.

Treatment Technique (TT): A required process intended to reduce the level of a contaminant in drinking water.

Waiver: State permission not to test for a specific contaminant.

N/A: Not applicable

NTU: Nephelometric Turbidity Units (a measure of water clarity)

pCi/l: Picocuries per liter (a measure of radioactivity)

ppm: Parts per million

ppb: Parts per billion

Notes:

  1. Turbidity is a measure of the clarity of water and has no health effects. Nevertheless, turbidity may interfere with disinfection and provides a medium for microbial growth.
  2. Must be less than 0.3 NTU in 95 percent of monthly samples. The higher the percentage the better.

Aurora is required to monitor its drinking water for specific contaminants on a regular basis. Results of regular monitoring are an indicator of whether or not our drinking water meets health standards.

Cryptosporidium

Cryptosporidium (crypto) is a microbial pathogen found in surface water throughout the United States. Aurora Water tested for crypto in 2017 and detected less than 0.091 organisms per liter in its source water. Current

test methods do not determine if these source water organisms are dead or if they are capable of causing disease. Although filtration removes crypto, the most commonly used filtration methods cannot guarantee 100 percent removal. Monitoring indicates the presence of this organism in our source water, but it has never been detected in our treated water.

Ingestion of crypto may cause cryptosporidiosis, an abdominal infection. Symptoms of infection include nausea, diarrhea and abdominal cramps. Most healthy individuals can overcome the disease within a few weeks.

However, immunocompromised people are at greater risk of developing a life-threatening illness. Immunocompromised individuals are encouraged to consult with their doctor about any appropriate precautions they should take to avoid infection. Cryptosporidium must be ingested to cause disease, and may be spread through means other than drinking water.

Lead

Aurora’s water supply does not contain lead, however, lead was one of several materials used prior to 1960 in service lines to connect buildings to the city’s water mains. Infants, young children and expectant mothers are typically more vulnerable to lead in drinking water than the general population. Aurora Water carefully monitors its water treatment processes to minimize the risk of service line corrosion.

If you are concerned about elevated lead levels in your home’s water, you may wish to have your water tested. In addition, you may consider flushing your tap for 30 seconds to two minutes before using tap water. Additional information on lead in drinking water is available from the Safe Drinking Water Hotline at 1.800.426.4791. You can also visit epa.gov/lead for more details.

Radon

Radon is a radioactive gas that you cannot see, taste or smell. It is found in the soil throughout the United States. Radon can move up through the ground and into a home through cracks and holes in the foundation. It can reach high levels in all types of homes. Radon can also be released from tap water from showering, washing dishes and other household activities. Compared to it entering the home through the soil, radon entering the home through tap water will be, in most cases, a small source of radon in indoor air.

Radon is a known human carcinogen. Breathing air that contains it can lead to lung cancer. Drinking water that contains radon may also cause increased risk of stomach cancer. If you are concerned about it in your home, test the air in your home. Testing is inexpensive and easy. Fix your home if the level in your air is four (4) picocuries per liter of air (pCi/L) or higher. There are simple ways to fix a radon problem that are relatively inexpensive. For additional information, call the state radon program at 303.692.3030 or call the EPA Radon Hotline at 800.SOS.RADON.

Source Water Assessment

The CDPHE has completed a source water assessment of the potential for contaminants reaching any of Aurora Water’s terminal supplies, the last stop for the water before it is treated. The potential sources of contamination that may exist are: EPA areas of concern; permitted wastewater discharge sites; above ground, underground and leaking storage tank sites; solid waste sites; existing or abandoned mine sites; other facilities; commercial, industrial and transportation activities; residential, urban recreational grasses; quarries, strip mines and gravel pits; agriculture; forests; septic systems; oil and gas wells and roads. For more information on the report, contact the CDPHE by calling 303.692.2000 or visiting Colorado. gov/cdphe/ccr. The report is located under “Guidance: Source Water Assessment Reports.”

The sources of drinking water (both tap water and bottled water) include

rivers, lakes, streams, ponds, reservoirs, springs and wells. As the 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 bacteria and viruses, which may come from wastewater treatment plants, septic systems, agricultural livestock operations and wildlife.
  • Inorganic contaminants, such as salts and metals, can be naturally occurring or result from urban stormwater runoff, industrial or domestic wastewater discharges, oil and gas production, mining or farming.
  • Pesticides and herbicides that come from a variety of sources such as agriculture, urban stormwater runoff and residential uses.
  • Organic chemical contaminants include synthetic and volatile organic chemicals, which are byproducts of industrial processes and petroleum production, and also may come from gas stations, urban stormwater runoff and septic systems.
  • Radioactive contaminants can be naturally occurring or the result of oil and gas production and mining activities.

To ensure tap water is safe to drink, the EPA prescribes regulations that limit the amount of certain contaminants in water provided by public water systems. The Food and Drug Administration regulations establish limits for contaminants in bottled water that must provide the same protection for public health.

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. Some people may be more vulnerable to contaminants in drinking water than the general population. Immunocompromised people, people with cancer undergoing chemotherapy, people who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly people and infants can be particularly at risk from infections. These people should seek advice about drinking water from their health care providers. The EPA and the Centers for Disease Control guidelines on appropriate means to lessen the risk of infection by crypto and other microbial contaminants are available from the Safe Drinking Water Hotline at 1.800.426.4791.

AURORA WATER’S DRINKING WATER TREATMENT FACILITIES

The Thomas J. Griswold and the Charles A. Wemlinger water purification facilities use direct filtration processes, which include coagulation, flocculation, filtration and disinfection. Both facilities have the capacity to treat up to 80 million gallons of water per day. The Peter D. Binney Water Purification Facility has two treatment trains. One train uses a conventional treatment process, which includes coagulation, flocculation, sedimentation and biological filtration and the other uses an advanced treatment process, which includes softening, advanced UV oxidation, biological filtration and granular activated carbon filtration. Both processes are then combined and undergo disinfection. The facility has the capacity to treat up to 50 million gallons of water per day.

All three facilities have achieved the Phase IV “Excellence in Treatment” designation, the highest level awarded by the Partnership for Safe Water (PSW). The PSW is an alliance of six prestigious drinking water organizations, including the American Water Works Association and U.S. Environmental Protection Agency. Aurora Water is the only water provider in the country to earn this designation at three facilities. To date, a total of 19 treatment plants in the United States have successfully achieved this designation.

Aurora Tap Water

Have you ever wondered if the Aurora Tap Water? I have to admit I was skeptical when I first saw it on TV. I thought, “Is this some kind of joke or is this for real?” The truth is if you are looking for great-tasting, filter-free tap water then this could be it.

You see our bodies only process so much of the various toxins and contaminants we come into contact with on a daily basis. Over time the build-up can become very severe and cause major health problems. Our bodies can not filter out enough contaminants in order to make us feel, look or even taste right. Water is life itself and without it, we would quickly become weak, dehydrated, and dying. It’s that simple.

Now, when I say that this drinking water is “filtered well” this does not mean that there are no chemicals or contaminants remaining in the tap water at all. What they do filter out is most of the harmful bacteria and parasites, as well as the heavy metals and herbicides that have found their way into our groundwater supplies over the years. I have been drinking this aqua product for about a month now and am thoroughly enjoying it. It does taste good and is moderately priced, and in my honest opinion – a far better value than the vast mountain of tap water that I was previously drinking!

Aurora Water

In case you are not familiar with the name, Aurora drinking water is a high-quality filtered tap water solution that has been manufactured to give you pure spring-like water. It comes from the Aurora Borealis National Park in Norway where the highest quality is found. There are no harmful chemicals or pesticides used in this filter and thus it is considered to be one of the best choices in the market. With its effectiveness and the benefits that it provides to you, it is no doubt that you will choose this water purifier to filter your water.

When you use this drinking water purifier, you do not need to worry about the loss of essential minerals found in normal tap water because it removes all these minerals which make the drinking water taste bad for most people. Moreover, it also removes any traces of calcium, iron, or sodium that can cause harm to your health. Since it uses a carbon base, no trace of minerals such as potassium or magnesium will be left in the final product. This makes it highly effective in eliminating all tap water contaminants, thus giving you crystal clear water.

You can enjoy the tap water that you drink without worrying about mineral deficiencies. This filter is easy to install and easy to maintain, which means you don’t have to worry about changing filters very often. It comes in an ideal compact size that makes it a practical choice. You can easily carry it in your bag or backpack and use it anywhere you go.

Aurora Drinking Water

Aurora drinking water has emerged as the leading selling item in the United States. The popularity of this product cannot be overlooked because it comes from such an unlikely source – an effort to improve the quality of human health in one of the coldest climates on Earth. In Arizona, the winter months can be brutal, literally, and temperatures drop below the freezing point of ice in some places. People who live there face a number of health issues that arise from being outdoors all day long. In an effort to alleviate these health problems, health-conscious people are looking for ways to warm their bodies inside and outside of their homes.

They turn to drink water purification devices to ensure that they are doing everything they can to maintain good health. Unfortunately, not all purification devices work the same, and some are downright substandard. Some purification systems offer only a tiny fraction of what you need to get rid of toxins and chemicals in your tap water. Other companies make outrageous claims about turning tap water into a “bio-active” substance. Despite these high claims, many experts advise that it would be impossible to produce such a substance and that such products do not have any real effect on your body.

When you buy a quality machine, you are getting a great investment in your health. A high-quality machine will use ultra-violet light to kill any organisms or bacteria that may be lurking in your drinking water. These methods are incredibly effective, but they require specialized equipment. For people who live in places that cannot afford these specialty items, it makes sense to choose a tap water purification system based on its ability to remove harmful toxins from your drinking water. With such a machine, you can feel confident that you are getting the best quality possible.

Aurora Water Safe to Drink

The long-awaited release of the new “Aurora” bottled water is causing quite a stir among consumers. The new product from the Aurora Company has all the benefits of traditional filtered purified tap water but at a much more reasonable price. Is the new water safe to eat?

There are some definite advantages to drinking this type of water. In addition to not having to worry about dangerous levels of chlorine and lead in the water due to the ion exchange process at the manufacturing plant, consumers are now getting the minerals they need in their drinking water. The minerals found naturally in groundwater are lost through the filtration process during the distillation process. Through the use of reverse osmosis, the company was able to replace the lost minerals. This is the same way all water companies purify their water in order to make it safe to drink for human consumption.

The only real disadvantage to the new water is found in the production of the Aurora product. The company spent millions of dollars developing the water and to not have any side effects present in the end is a huge positive. Unfortunately, some of the bacteria still found in traditional water bottles can still be found in the final product. In addition to this, consumers might be finding that they are negatively affected by the added sugar content of the final product. Sugar can be a positive thing as long as it is eaten in moderation, but if consumed too much it can have some negative consequences on the body.

Aurora Water Sources

The first thing that we need to do is figure out what exactly makes up this type of water. When we figure that out, it will be easier for us to find the uses for it. This article will give you all the basic information that you need about these types of water sources so that you can know exactly what they are and how they work.

The first thing that these sources do is provide minerals to our drinking water. You may not have heard about them much until now, but they really are quite important. In fact, there are a lot of minerals that we get from our environment that we cannot get from drinking water alone. These minerals can come from the clay and other rocks that are found in our environment. Once we add certain minerals to our tap water, we find that it becomes clearer for us to drink.

Do you ever find that you are losing hair or getting skin problems because your drinking water is contaminated? Many people don’t realize this problem until it is too late. This is why you will want to make sure that you are keeping your drinking water sources clean with these amazing minerals. You will be surprised at the many different benefits of having them around. We are going to cover the basics of them in a future article, but until then just keep reading and you will be able to find out everything that you need to know.

Aurora Water Treatment

For years, people have relied on Aurora Water Treatment in Boulder, Colorado to help give them clean and safe to drink water. The city of Boulder actually took a long time to develop its own water treatment facility. Although it has long been the capital of the water treatment industry, Boulder did not get its start until the nineteen seventies when it was first used as a ski resort town. Today, with all of its technological advancements, it is easier than ever for homeowners to have easy access to clean, freshwater from their home tap water purification system.

The city of Boulder actually uses over seven thousand feet of the underground piping system to convey clean, filtered water throughout the city. Every water outlet has a registered color code to signify what the water contains, which can be used to make any responsible decision on the best option for your family’s drinking supply. Because of the system’s high degree of filtration, you will never have to worry about the chemicals in your water messing up your body or leaving behind dangerous metals in your hair to find a way home. Aurora Water Treatment has actually cleaned off a number of dangerous contaminants, including mercury, cadmium, and chromium. They even have a special PH level indicator that helps the water pass through the plumbing system with ease and makes sure that the water doesn’t have to pass through several different filters before being categorized and marked as clean.

With over fourteen hundred licensed water providers in the Boulder area, it is important that you make sure that you only deal with the most established companies. There are quite a few fly-by-night companies that have popped up in recent years offering their water purification services. Be sure to always ask a company how old they are, where they are located, and what their process is. If a company cannot answer these questions quickly or easily, look elsewhere for a cleaner alternative. Aurora Water Treatment, in Boulder and throughout the rest of Colorado, is the best place to go if you want clean, purified water.

Aurora Drinking Water Quality

It’s time to take a long hard look at your Aurora drinking water quality. This is the single most important thing you can do to protect your home and your family from the possible dangers of low-quality drinking liquid. We have all seen television commercials about the new “carbon filtering” systems being endorsed by some of the largest bottled beverage companies. While these systems are supposed to improve the quality of our tap liquid, the reality is that they just mask the problem instead of solving it.

Carbon filtering systems simply remove some of the material that makes up the carbon base of the water. So while it may technically improve the quality of your liquid, the problems that are created by removing these impurities from the water will still exist. The only way to be completely safe is to have a complete water purification system installed in your home. There is no other solution that will remove all of the contaminants that are lurking in our tap water.

One of the biggest ways that we are harming our health is through the consumption of unsafe tap liquid. So it is absolutely critical that we make sure that we are taking every step necessary to ensure that we are always getting the highest quality liquid available. While there is nothing that you can do to change the number of impurities that may be present in any particular area, you can make a difference in how you react to those impurities. Simply purchasing a system that offers a high level of filtering will make a huge difference in your ability to protect yourself and your family from the many different contaminants that can find their way into your home. By purchasing a high-quality water filter system, you will be taking the first steps toward ensuring that your family remains healthy.
