Can You Drink Tap Water in Azusa?
Yes, Azusa's tap water is generally considered safe to drink as Azusa 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, Azusa's water utility, Azusa Light and Water, 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 Azusa Light and Water 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 Azusa Tap Water
The most recent publicly available numbers for measured contaminant levels in Azusa 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 Azusa's water quality reports, or getting your home's tap water tested to see if you should be filtering your water.
Azusa Tap Water Safe Drinking Water Act Violation History - Prior 10 Years
Below is a ten year history of violations for the water system named Azusa Light and Water for Azusa in California. For more details please see the "What do these Violations Mean?" section below.
Is there Lead in Azusa Water?
Based on the EPA’s ECHO Database, 90% of the samples taken from the Azusa water system, Azusa Light and Water, between sample start date and sample end date, were at or below, 0.0 mg/L of lead in Azusa water. This is 0% of the 0.015 mg/L action level. This means 10% of the samples taken from Azusa contained more lead.
While Azusa water testing may have found 0.0 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 Azusa 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 - AZUSA CA NCCOSC MORRIS DA - near Azusa 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 Azusa 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
- Maximum contaminant levels (MCLs) - maximum allowed contaminant level was exceeded.
- Maximum residual disinfectant levels (MRDLs) - maximum allowed disinfectant level was exceeded.
- Other violations (Other) - the exact required process to reduce the amounts of contaminants in drinking water was not followed.
Non-Health Based Violations
- 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.
- 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.
- Other violations (Other) - miscellaneous violations, such as failure to issue annual consumer confidence reports or maintain required records.

The Azusa Water System
The City of Azusa, a municipality incorporated December 29, 1898, maintains ownership and operation of the municipal utility referred to as Azusa Light & Water (ALW). ALW is entrusted with the responsibility for providing water utility service within its municipal boundaries, and, since acquiring the Azusa Valley Water Company in 1993, providing water utility service to portions of the communities surrounding the City of Azusa. Serving approximately 24,077 active service connections with an estimated customer population of 106,400, the combined and integrated water systems of the City of Azusa and the Azusa Valley Water Company comprise Azusa Light & Water, the largest municipal water utility in the San Gabriel Valley.

Azusa produces its water from the upper reaches of the San Gabriel River, near the mouth of San Gabriel Canyon, far upstream of the contaminated groundwater zones found elsewhere in the San Gabriel Valley.
Contamination Limits
Drinking water may reasonably be expected to contain at least small amounts of contaminants. 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 activities. The presence of contaminants does not necessarily indicate that drinking 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-
Nitrates
Nitrate in drinking water at levels above 10 mg/L, measured in Nitrate as Nitrogen, is considered a health risk for infants of less than six months of age. High Nitrate levels in drinking water can interfere with the capacity of the infant’s blood to carry oxygen, resulting in serious illness; symptoms include shortness of breath and blueness of the skin. High Nitrate levels may also affect the ability of the blood to carry oxygen in other individuals, such as pregnant women and those with specific enzyme deficiencies.
Well Nitrate levels may rise for short periods of time due to rainfall or agricultural activity. Where higher Nitrate levels are present, you should seek advice from your healthcare provider or choose to use bottled water for mixing formula and juice for your baby; if you are pregnant, you should drink bottled water. Water purveyors are required by DDW regulations to issue warnings to customers when drinking water nitrate levels exceed 10 mg/L. Average Nitrate levels
Immuno-
Compromised
People
Some people may be more vulnerable to constituents in the water than the general population.
chemotherapy, persons with HIV/AIDS or other immune system disorders, some elderly persons, and infants, can be particularly at risk from infections.
These people should seek advice about drinking water from their healthcare providers. USEPA/Centers for Disease Control (CDC) guidelines on appropri- ate means to lessen the risk of infection from microbial contaminants are available from the Safe Drinking Water Hotline
Definitions
Notification Level & Action Level —
The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.
Cryptosporidium — A microscopic organism which, when ingested, can cause diarrhea, fever and other gastrointestinal symptoms. The organism comes from animal waste and may occur in surface watersheds. If detected, cryptosporidium is eliminated by an effective treatment combination including sedimentation, filtration and disinfection.

Definitions (cont.)
Maximum Contaminant Level Goal
(MCLG) — The level of contaminant in drinking water below which there is no known or expected risk to health. Maximum contaminant level goals are set by the EPA.
Maximum Residual Disinfectant
Level (MRDL) — The level of a disinfectant added for water treatment that may not be exceeded at the consumer’s tap.
Maximum Residual Disinfectant
Level Goal (MRDLG) — The level of a disinfectant added for water treatment below which there is no known or expected risk to health. MRDLGs are set by the U.S. EPA.
Maximum Contaminant Level (MCL)
- The highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the public health goals and maximum contaminant level goals as is economically and technologically practicable.
Primary Drinking Water Standard —
Primary maximum contaminant levels, specific treatment techniques adopted in lieu of primary MCLs, and
monitoring and reporting requirements for MCLs that are specified in regulation.
Public Health Goals (PHG) — The level of a contaminant in drinking water below which there is no known or expected risk to health. Public health goals are set by the California Environmental Protection Agency.

sampled in the Azusa distribution system range from, ND to 6.0 mg/L Nitrate as Nitrogen for groundwater and ND (nondetectable) for surface water.
Trihalomethanes
Trihalomethanes (THM’s) are a family of disinfection byproduct chemicals formed when a disinfectant such as chlorine is added to the water supply and mixes with naturally occurring organic material found primarily in Surface Water. Disinfection is an important and necessary step in the water treatment process that protects against harmful bacteria and other potential contamination. Chlorine is the most widely used and approved water system disinfectant in the United States.
The amount of Total THM’s allowed in drinking water is regulated by the EPA, which has set a Total THM (TTHM) annual average safe limit of 80 μg/L in drinking water. Results of a health study released in early 1998 suggest that women who drink five glasses of water daily and are in the first three months of pregnancy may have an increased risk of miscarriage from TTHM levels in drinking water above 80 μg/L. State officials have cautioned that the study is not definitive and have stated that more study on the issue is needed. Average TTHM levels sampled in the Azusa distribution system for all four quarters in 2020 are 41.3 μg/L for the groundwater and surface water blend.
This Consumer Confidence Report reflects changes in drinking water regulatory requirements during 2016. All water systems are required to comply with the state Total Coliform Rule. Beginning April 1, 2016, all water systems are also required to comply with the federal Revised Total Coliform Rule. The new federal rule maintains the purpose to protect public health by ensuring the integrity of the drinking water distribution system and monitoring for the presence of microbials (i.e. total coliform and E. coli bacteria). The USEPA anticipates greater public health protection as the new rule requires water systems that are vulnerable to microbial contamination to identify and fix problems. Water systems that exceed a specified frequency of total coliform occurrences are required to conduct an assessment to determine if any sanitary defects exists. If found, these must be corrected by the water system.
To maintain high quality water, Water Treatment Plant Operators certified by the State Water Resources Control Board Division of Drinking Water (DDW) are operating Azusa’s Joseph F. Hsu Water Filtration Plant on a regular basis, treating and monitoring the quality of the drinking water we serve.
Drinking Water Contaminants
Inorganic contaminants — Salts and metals, which can be naturally occurring or result from urban stormwater runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming.
Microbial contaminants — Viruses and bacteria which may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife.
Organic chemical contaminants — Synthetic and volatile organic chemicals, which are byproducts of industrial processes and petroleum production, and can also come from gas stations, urban stormwater runoff, and septic systems.
Pesticides and herbicides — Can come from a variety of sources such as agriculture, urban or stormwater runoff, and residential uses.
Radon — Can be naturally occurring or the result of oil and gas production and mining activities.
Perchlorate — Some people who drink water containing perchlorate in excess of the notification level may experience effects associated with hypothyroidism. Perchlorate interferes with the production of thyroid hormones, which are required for normal pre- and postnatal development in humans, as well as normal body metabolism.
Arsenic — 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. Environmental Protection Agency continues to research the health effects of the 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.

showering, washing dishes, and other household activities. Radon entering the home through tap water will, in most cases, be a small source in indoor air as compared to radon entering the home through soil. Radon is a known carcinogen and breathing air containing radon can lead to lung cancer. Drinking water containing radon may cause increased risk of stomach cancer. If you are concerned about radon, testing the air in your home is inexpensive and easy. For information call EPA’s Radon Hotline
Treatment Technique — A required process intended to reduce the level of a contaminant in drinking water.
Turbidity — A measure of the cloudiness of the water. Turbidity is monitored because it is a good indicator of water quality. High turbidity can hinder the effectiveness of disinfection.
Variance — State or EPA may give permission not to meet an MCL or a treatment technique under certain conditions.ADON).
Unregulated
Contaminants
Boron — Some men who drink water containing boron in excess of the notification level over many years may experience reproductive effects, based on studies in laboratory animals.
Manganese — Manganese exposures resulted in neurological effects. High levels of manganese in people have been shown to result in adverse effects to the nervous system.

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. Azusa Light & Water is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cooking. If you are concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline or at http://www.epa.gov/lead.
LEAD TESTING IN SCHOOLS
The State Water Resources Control Board, Division of Drinking Water (DDW), in collaboration with the California Department of Education, have taken the initiative to test for Lead in drinking water at all public schools serving kindergarten or any of grades
