Can You Drink Tap Water in Glendale?

Yes, Glendale's tap water is generally considered safe to drink as Glendale 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 Glendale's local Twitter account.

According the EPA’s ECHO database, from April 30, 2019 to June 30, 2022, Glendale's water utility, Glendale-City, Water Dept, had 0 violations of the Safe Drinking Water Act. For more details on the violations, please see our violation history section below. This assessment is based on the Glendale-City, Water Dept 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 Glendale Tap Water

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

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

Below is a ten year history of violations for the water system named Glendale-City, Water Dept for Glendale in California. For more details please see the "What do these Violations Mean?" section below.

Is there Lead in Glendale Water?

Based on the EPA’s ECHO Database, 90% of the samples taken from the Glendale water system, Glendale-City, Water Dept, between sample start date and sample end date, were at or below, 0.0041 mg/L of lead in Glendale water. This is 27.3% of the 0.015 mg/L action level. This means 10% of the samples taken from Glendale contained more lead.

While Glendale water testing may have found 0.0041 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 Glendale 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 - DFSP Norwalk - near Glendale 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 Glendale 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.

IMPORTANT INFORMATION

ABOUT YOUR DRINKING WATER

The water delivered to you by Glendale Water & Power continuously passes tough State and Federal quality standards. This booklet is a detailed report on the water we delivered

to you in 2020.

State and Federal Regulation

In order to ensure that tap water is safe to drink, the U.S. Environmental Protection Agency (U.S. EPA) and the State Water Board (Department) prescribe regulations that limit the amount of certain contaminants in water provided by public water systems. State Water Board regulations also establish limits for contaminants in bottled water that provide the same protection for public health.

Customer Participation and Assistance

Comments from the public are welcome and may be presented at the Glendale Water & Power Commission meetings held the first Monday of each month, at 4:00PM, at 633 E. Broadway, Room 105 (MSB 105)..

A Message from Michael De Ghetto, Chief Assistant General Manager - Water

Glendale Water & Power (GWP) is committed to the safety of the water served to the residents and businesses in Glendale and in 2020 the City’s water continued to meet all federal, state and local water quality standards. The dedication, personal commitment, and technical expertise of Glendale Water

  • Power’s water professionals continued to ensure the safety of the water served to the residents of Glendale during

the COVID-19 pandemic. As designated essential workers by the State and Federal Government, Water Quality Section staff not only continued to maintain the safety of Glendale’s drinking water, they also continued to improve it by implementing a portable chloramination system that can be moved to different facilities as needed to improve the chloramine residual as needed. GWP’s Water Engineering team continued to oversee the operation of the Glendale Water Treatment Plant (GWTP), and GWP received two

updates to the City’s “permit to operate a water system” related to continuous improvements at the GWTP. To ensure the continued safety of Glendale’s water GWP’s staff take more than 5,700 water quality samples every year and they monitor the testing and compliance of over 2,800 backflow prevention assemblies that help ensure contamination does not enter the water system. In addition, GWP is committed to the environment and has been reducing the City’s reliance on imported water through the use of recycled water system which has been in operation since 1978, and by cleaning up local groundwater to drinking water standards for over 20 years at the GWTP as part of an EPA Superfund clean-up project. By having this treatment plant in place, GWP has been able to protect the City’s water supply even as new types of contaminants are discovered in the environment. GWP is Glendale owned and Glendale focused, and this focus extends to GWP’s team of water professionals and the work they do to ensure the quality and sustainability of all of the City’s sources of water.

Frequently Asked Questions

Why does my water leave a white residue on glass and metal surfaces?

The white, crusty residue sometime left behind when water dries on a surface is a product of water hardness. Hardness is basically an indication of the presence of minerals in water. Minerals are naturally occurring and do not pose a health risk. Mineral

Why do GWP crews let water run down the street?

One way GWP maintains water quality is by cleaning pipelines using a flushing process to clean out sediment and minimize the potential for stagnant water. This process maintains disinfectant residuals and reduces the chances of bacterial growth in the water distribution system. Pipeline cleaning is an important, routine process and a non-wasteful, beneficial use of water.

Cross-Connection Control Program

To protect drinking water systems from potential contamination, State law requires that utilities like GWP, maintain an effective Cross-Connection Control Program. A cross-connection can occur when a potable water line is directly or indirectly connected to an unknown supply. Regulations require installation of backflow prevention devices at all locations where actual or potential cross-connections exist. An unprotected or

Recycled Water

The drought in the late 1980s paved the way for Glendale to develop an alternative source of water for non-potable uses. This alternative source is recycled water. Within Glendale, we have two separate water systems, one for drinking water and one for recycled water. Recycled water is domestic wastewater that undergoes extensive treatment. Glendale’s supply of recycled water comes from the Los Angeles/Glendale Water Reclamation Plant which produces 14 million gallons of recycled water per day. Even though the end product of all of this treatment meets Federal and State drinking water standards, recycled water cannot be used for human consumption. Glendale’s recycled water system helps minimize the impacts of drought and helps conserve our valuable sources of drinking water. Currently, recycled water use in Glendale is 6% of the total annual water used. GWP has 85 service connections that provide recycled water for public area irrigation, cooling towers, street cleaning, dust abatement, and flushing urinals and toilets in several dual- plumbed buildings. Glendale businesses and agencies using recycled water save significant costs over the use of drinking water. As the importance of water conservation becomes greater than ever, increasing our use of recycled water will improve our chances of meeting our water conservation goals while still meeting the water needs of all our customers. This will also reduce the costs of

deposits, usually calcium, may form in larger quantities in water that is either too hot or too cold; this is why customer frequently see deposits on tea kettles and in ice cubes. A mild vinegar solution is usually sufficient to clean fresh mineral deposits on glass and metal surfaces.

My drinking water is reddish brown. Why?

Reddish-brown water can be caused by rust dislodged from the drinking water pipes in the street, those leading to, or inside, your home, or from your hot water tank. If you are having trouble and your neighbors are not, then the color is likely originating somewhere in your plumbing system. Let your water run until it clears up before using it.

Should I install a home water treatment device?

This is a personal decision. These devices are not needed to make the water meet federal, state, or local standards. In fact, if the devices are not properly maintained, they may cause problems of their own. You may consider a home treatment device if you desire to change the taste of your water.

How is the inside of a pipe cleaned after a water main break?

After the work is done, the inside of the pipes are disinfected with a chlorine solution to kill off germs. In some cases, water is flushed through the main at a high velocity by opening a fire hydrant which also allows the water main to be cleaned.

My water often looks cloudy when taken from a faucet and then clears up. Why?

The cloudy or milky water is caused by tiny air bubbles. After a while, the bubbles rise to the top and dissipate into the air. The cloudiness occurs more often in the winter when the drinking water is cold. Air in water does not pose a health risk.

Why does my water smell like a rotten egg?

The most common cause of the rotten egg or sewage smell is from the gases released by bacterial growth in drain pipes. When you run your faucets, the water enters the drain pipe and forces these gases out, resulting in the smell. To determine if the smell is coming from the drain or the water, fill a glass with water, take it into another room and smell the water in the glass. If you do not smell the same odor from the water in the glass, then the odor is coming from the drain. Cleaning the drain with a mild bleach solution should resolve the problem.

Why does my water smell like chlorine?

State and Federal regulations require that water utilities, including GWP, maintain a disinfectant residual throughout the distribution system. The purpose is to prevent water-borne illnesses by suppressing the growth of bacteria and other potential contaminants. GWP, like many other utilities, uses chlorine and chloramines to comply with these requirements. You may, at times, experience a chlorine taste or odor.

inadequately protected cross-connection could contaminate the City’s drinking water supply. Examples of potential cross- connections include fire sprinkler systems, lawn irrigation, cooling systems and high pressure boilers. Implementing an effective cross-connection control program involves conducting facility inspections, evaluating the degree of potential hazard to public health, identifying the appropriate protection device, and providing training for onsite supervisors. Once devices are installed, there is a need for regular inspections and testing to ensure their proper operation as well as maintenance of accurate and up-to-date records. In 2020, GWP oversaw the testing and maintenance of 2812 backflow devices, 97% of which were in compliance with State regulations. Glendale has never experienced contamination due to a cross-connection.

  1. Aluminum has a secondary MCL of 200 ppb.
  2. Total coliform MCL: No more than 5% of the monthly samples may be total coliform-positive.
  3. Lead and Copper Rule compliance based on 90th percentile of all samples being below the action level. Samples were taken from 50 customer taps. Testing is required every three years.
    This data was collected in 2020. Next testing is in 2023. In 2018, GWP conducted Lead testing at 25 schools per the request of Glendale Unified School District.
  4. Copper has a secondary MCL of 1000 ppb.
  1. Analysis was on water before blending with MWD supply.
  2. Compliance is based on Locational Running Annual Average (LRAA) for the stage 2 DBPR. “Citywide Average” represents highest LRAA.
  3. Hardness in grains/gallon can be found by dividing ppm by 17.1.
  4. For GWP sources, data represents the amount of naturally occuring fluoride. For MWD sources, data is after fluoride added at MWD treatment plant. Glendale’s distribution system fluoride levels were monitored in 2020 - range 0.45 ppm - 0.86 ppm with an average of 0.67 ppm.
  5. Foothill Well was offline throughout 2020; thus, no data is available for this source. The Well will be returned to service after rehabilitation.
  6. AI < 10.0 = Highly aggressive and very corrosive water. AI >/= 12 = Non-aggressive water. AI (1.0 - 11.9) - Moderately aggressive water.
  7. Compliance was based on RAA. Bromate was tested at effluent of Jensen (ki) and Weymouth (kii) Treatment Plants where ozone is used as a disinfectant.
  8. While your drinking water meets the federal and state standard for arsenic, it does contain low levels of arsenic. The arsenic standard balances the current understanding of arsenic’s possible health effects against the costs of removing arsenic from drinking water. The U.S. Evirontmental Protection Agency 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.
  9. The State allows us to monitor for some contaminants less than once per year because the concentrations of these contaminants do not change frequently. Some of our data, though representative, are more than one year old. Radiological sampling was last conducted in June 2020.
  10. Turbidity is a measure of the cloudiness of the water.
    We monitor it because it is a good indicator of water quality. High turbidity can hinder the effectiveness of disinfectants.

REGULATED CONTAMINANTS WITH SECONDARY MCLS

 

 

 

 

 

 

 

Nitrate

Nitrate levels may rise quickly for short periods of time because of rainfall or agricultural activity. Nitrate in drinking water at levels above 10 mg/L is a health risk for infants of less than six months of age. Such nitrate levels in drinking water can interfere with the capacity of the infant’s blood to carry oxygen, resulting in a serious illness; symptoms include shortness of breath and blueness of the skin. Nitrate levels above 10 mg/L may also affect the ability of the blood to carry oxygen in other individuals, such as pregnant women and those with certain specific enzyme deficiencies. If you are caring for an infant, or you are pregnant, you should ask advice from your health care provider. Glendale’s water is tested at the source for contamination then treated to maintain levels below the MCL to ensure the water delivered to our customers is safe to drink.

Lead

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. GWP 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 www.epa.gov/lead.

Water Quality Terms in This Report

Maximum Contaminant Level (MCL):

The highest level of a contaminant that is allowed in drinking water. Primary MCLs are set as close to the PHGs (or MCLGs) as is economically and technologically feasible. Secondary MCLs are set to protect the odor, taste, and appearance of drinking water.

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 are set by the USEPA.

Public Health Goal (PHG):

The level of a contaminant in drinking water below which there is no known or expected risk to health. PHGs are set by the CalEPA.

Primary Drinking Water Standard (PDWS):

MCLs and MRDLs and treatment techniques (TTs) for contaminants that affect health along with their monitoring and reporting requirements.

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 drinking water disinfectant 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.

Regulatory Action Level:

The concentration of a contaminant which, if exceeded, triggers treatment or other requirements that a water system must follow.

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

Source Water Contaminants

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, may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife.

Inorganic Contaminants, such as salts and metals, that 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, that 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 by-products of industrial processes and petroleum production, and can come from gas stations, urban storm water runoff, agricultural application, and septic systems.

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

Disinfection By-Products, which include Trihalomethanes (THMs) and Haloacetic Acids (HAAs), are generated by the interaction between naturally occurring matter and disinfectants, such as chlorine.

Sources of Glendale’s Water

In 2020 Glendale Water and Power delivered 8 billion gallons of potable water to our customers. 59% was purchased from the Metropolitan Water District, after being imported and treated from Northern California and the Colorado River. 34% comes from local groundwater sources extracted from the Verdugo and San Fernando Basins. In addition, 7% of total water used in 2020 was recycled water delivered by the Los Angeles-Glendale Water Reclamation Plant. The plant’s highly treated waste water meets or exceeds the water quality standards for recycled water and is used ONLY for irrigation and industrial processes.

Important Information for People with Compromised Immune Systems

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. USEPA/Centers for Disease Control (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 (1-800-426-4791).

Explanation Regarding Contaminants

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 by calling the USEPA’s Safe Drinking Water Hotline (1-800-426-4791).

Glendale Tap Water

Glendale Tap Water Filter offers some of the cleanest drinking water in Southern California. There is an oversized filter located on the roof, but since it is a roof that can occasionally be breezy, sometimes it rains, and that means that the water can flow into other parts of the park. Glendale has a high percentage of people who have to pay for water at each stop, which means they are getting filthy water. The water tastes terrible and has chemicals in it from the treatment plant.

If you use the tap water at your home or business and then use the filter, there is no reason to drink that water. The filter will take out any of the chemicals and other things that could harm you. You will still get all of the healthy minerals in tap water, such as potassium and calcium. Glendale also sells an air cooler, refrigerator, and grill. The filter is easy to remove and replace, so you do not need to worry about buying a new air cooler or refrigerator when it gets old.

Glendale has two water stations, but it is recommended that you do not drink from any station that is within the city limits. The water from these stations has been filtered and is the safest water for you to drink. It will not harm your body, and it will keep you hydrated. When you visit Glendale, you can see where all of the water stations are located and see where the filter is located. You can take a test drive of this water system and see if it is right for you.

Glendale Drinking Water

It is widely known that the Glendale drinking water treatment facility is considered to be among the best municipal water treatment centers in the United States. It is not uncommon for people in this area to visit the treatment facility themselves to test their water quality. If you live in or around Glendale, you know that drinking clean water from your tap can be very important indeed. The problem is that many people don’t have any idea where to get high-quality drinking water. Luckily, when you choose to use a water filter for your home, there is no need for frustration.

When you are shopping for a drinking water filtration system for your home, you should keep a few things in mind. The first thing you want to think about is cost. Since the amount of money you will spend to purchase and install a filtering system will vary greatly, you need to make sure that you do not overpay.

Another thing that you need to think about is what kind of water you drink. Glendale is a busy city, so their supply will be much different from the supply they receive at home. Also, Glendale is a large metropolis, so you will probably end up having to use a filter for your drinking water more than once. Even if you only have a water filter for drinking at home, you still need to remember to replace the cartridges regularly to ensure that your drinking water remains as pure as possible. Of course, you can also buy water filters for your showerheads and other areas of your home, but these tend to be a bit more expensive. Since you will probably be using a water filter for most of your drinking water, it may make more financial sense to purchase a good water filtration system and spend the extra money than to go out and buy several different ones for different parts of your home.

Glendale Water Quality

Glendale is one of the towns in Southern California, suffering from drought problems for quite a while now. It has seen a drop in the amount of rainfall over the past few years and, as a result, has started to suffer from deteriorating water quality. Glendale has implemented several water conservation measures to curb this problem, most notably banning wooding on roads and within the city limits. In the past, the town relied on wells as its primary source of water. However, with the increasing demand for bottled water in Glendale, many are now turning to other sources such as boreholes and underground pools to meet their water requirements. However, as a precautionary measure, Glendale has insisted that any resident who wants to take any of these alternative measures must first get a water report from the town water plant.

The quality of Glendale’s tap water depends mainly on where it was acquired. The most common way of developing this is through the tap of the resident. The type of water found in the area is usually of poor quality, as most of it originates from the wastewater treatment plants of major cities throughout California. These wastewater treatment plants, among others, have a poor environmental track record and often contaminate drinking water, primarily if they are not appropriately maintained.

Although the towns have made efforts to improve the local streams and rivers’ water quality, these measures have yet to bear any results. Even if there is some trace of pollutants in the water, it would be too late to affect the water supply before it leaves the reservoir. On the other hand, boreholes are an excellent way of detecting if there has been any contamination in the groundwater, as many such homeowners are now opting for these alternatives over installing expensive filtration systems.

Glendale Water Utility

Glendale is a small city on Phoenix’s outskirts in southern Arizona, just east of the San Diego border. Glendale sits just below the famous Red Rock desert. It is a popular tourist destination because of the many beautiful hiking, fishing, and RV attractions that the city offers to visitors from out of town. Many Glendale water utility companies provide water services for the region. This article will take a look at one of them. This company is called Arizona Natural Gas. It provides both hot and cold water and was recently sold to a local business owner who happens to be very successful with his business.

Glendale’s city is quite progressive in its views on water conservation and waste management and has made some headway in these efforts in recent years. As a result of these efforts, many people who live in or near Glendale and work at businesses that deal with water utility issues tend to have very positive feelings about the city. Many of them take great pride in their community and the level of government support they feel. It should be noted that this positive attitude is not necessarily shared by all residents but more so by Glendale’s business owners, as most of them tend to take a very laissez-faire attitude to issues of public safety and waste management.

One such business owner is Johnnie Johnson. Mr. Johnson owns and runs two RV parks in Glendale. He also owns this water utility company that serves the area. He started his business in the early 90s and, at the time, was pretty new to the industry. Mr. Johnson said that he tried to get the city to install new meters on his water utilities, but they wouldn’t budge. They felt it wasn’t necessary. He decided to pursue the matter using the government as a means to get what he wanted.

Glendale Water Quality Report

A Glendale water report can be as informative as it is frightening. The city is located right in the heart of Southern California’s beautiful Orange County, so you know that you’re in good hands with this team of experts. After you dig into their report, you learn some of why you should care about what they found.

First of all, when you own a piece of land and manage a water body, you have a responsibility to protect that water for future generations. This means that a well must be well-maintained, not only from leaks but also from heavy corrosion caused by weathering, so that you don’t end up poisoning your children or your grandchildren. This also means that when you get a report from a lab, you know that you’re going to be accumulating high-quality water, no matter where you drill into the earth. This is because state law mandates that we have minimum standards, and a company cannot make up any of these standards. The result is that you’ll have clean, clear, safe water for your home well.

That’s the good news. Now, the bad news. A Glendale water report doesn’t tell you everything you need to know. For instance, one of the most dangerous minerals in groundwater that Glendale is concerned about is arsenic. So, while the city does test for this and other metals, they haven’t tested for arsenic and other chemicals that could contaminate the groundwater, which means that your kids are at risk, too.

Glendale Water Treatment Plant

The Glendale water treatment plant is located in the center of suburbia. It is run by the city of Glendale, a community of more than 25 thousand people. The City of Glendale, AZ, takes pride in being one of the most environmentally conscious communities in all of Arizona. The city is proud to be the state’s LEED-certified green building association. The water treatment plant itself has been certified by the Environmental Protection Agency as one of the best low-cost, high-quality water treatment and prevention plants around.

The facility itself operates two treatment centers, one indoors at the city hall and the other outdoors at the nearby community park. The indoor facility serves about thirteen thousand people every day, while the outdoor facility serves two to three thousand people on any given day. The Glendale water treatment plant processes more than four hundred tons of water each day. The plant can process three hundred tons per day, making it the largest water treatment plant in the entire state.

While many cities and residents of Glendale want the plant to shut down, the city council passed a resolution in June of 2021 which states that they expect the plant to remain operational until 2021. This resolution was put into effect so that Glendale’s citizens will have a clear understanding of what is happening at the water treatment plant. These are steps that every Arizona city should take to maintain a clean and healthy environment for its residents.

Glendale Drinking Water Standards

Glendale, AZ, has some excellent drinking water standards. The city keeps regular testing to ensure the water supply is safe by ensuring the quality meets or exceeds EPA standards. They also install treatment systems where needed, but this process has proved to be quite costly. It costs about ten thousand dollars to treat a gallon of water, so most of the city’s water is treated through reverse osmosis. A more affordable solution would be to use granular carbon with carbon blocks or carbon granules.

Since there are so many contaminants in the drinking water, the EPA has established multiple drinking water standards. These are set for strength, acidity, and other characteristics of the water. There are no requirements on how the treated water should be disposed of. Currently, it is illegal to throw the water away, but that will change as environmental laws become more strict.

You can help ensure your family’s health by ensuring that your tap water meets EPA drinking water standards. If you have noticed a change in the taste or smell or are noticing cloudy spots or discoloration, call your local water department immediately. You can also purchase an effective home purifier, which will eliminate any chlorine, volatile organic compounds, pesticides, herbicides, or other contaminants from your drinking water. These can be particularly effective if used together with a granular carbon filter.
