At AC by J, we understand the importance of having premium water quality in your Phoenix Valley, AZ, home. So when answering the question, “Is There a Water Quality Problem?” it is crucial to take a closer look at the Valley’s water sources and detected contaminants to unveil a fuller picture.

To provide you with up-to-date and accurate information the following information was gathered from the U.S. Environmental Protection Agency (EPA) and the 2023 Water Quality Report.

Read on with us to gain a comprehensive understanding of the source of Phoenix Valley water, the types of contaminants, and ways to combat the impurities found in your water.

Source of Phoneix Valley Drinking Water:

Before the 1980s, the Valley relied entirely on groundwater. Today, the city’s water comes primarily from renewable surface water and recycled water from the Colorado River, Salt River Project, and aquifers.

So, to break that down more:

Surface Water:

The Colorado River, channeled through the Central Arizona Project canal, is a key source. The CAP Water Treatment Plant employs conventional and advanced processes, ensuring rigorous water treatment. Additionally, the Verde and Salt rivers contribute to the Chaparral Water Treatment Plant.

Recycled Water:

Places in the Valley, like Scottsdale, boast the world’s most advanced water recycling facilities. This plant not only treats water for direct use but also aids in groundwater replenishment and turf irrigation, passing federal drinking water regulations.


While groundwater remains a component, the Valley now relies on a fraction of aquifers, maintaining active wells and employing stringent treatment overseen by regulatory bodies like ADEQ, EPA, and Maricopa County.

Contaminants in the Valley’s Tap Water – Unveiling the Truth

Arsenic Levels:

While meeting EPA standards in 2023, arsenic levels up to 6.7 parts per billion are reported. It is recommended to take action if levels exceed 1 part per billion, particularly in homes with children.

Chromium 6 Concentrations:

Elevated levels of Chromium 6, an unregulated highly toxic metal, pose risks. It is strongly advised to to take proactive steps to remove this hazardous metal from their drinking water. This ends up in our water due to industrial pollution or natural occurrences in mineral deposits and groundwater.

Disinfection Byproducts (DBPs):

Formation of DBPs, while not well-regulated, can be associated with health risks. At home whole-home water filtration addresses these emerging contaminants effectively.

Lead Presence:

Although current lead levels comply with regulations, vigilance is urged due to the potential risks associated with aging lead service pipes and plumbing. Luckily, our team offers exceptional repiping solutions.


Fluctuations in nitrate concentrations within surface water sources can swiftly escalate during brief intervals, often triggered by rainfall or agricultural practices.

Is Municipal Water Treatment Enough For Safe Water?

More than likely, no. Just because water passes federal standards doesn’t mean it’s entirely safe. Phoenix Valley’s water, while meeting legalities, still harbors various impurities. And to us, safeguarding your family’s well-being goes beyond what meets the “legal standard”.

While municipal water treatment is designed to meet safety standards and eliminate various contaminants, the legal limits of tap water contaminants have not been updated in almost 20 years to meet current health standards and education.

Despite municipal efforts, testing water at home and employing appropriate filtration systems ensures an added layer of safety, providing you with confidence in the quality of you and your families drinking water.

At AC by J, we care about more than just meeting regulations – we care about your health. We’re not just providing water services; we’re ensuring a safer, healthier future for you and your loved ones.

Filtration Solutions for Peace of Mind

For those wary of the detected contaminants, at-home drinking water filtration systems emerge as a safe and easy solution. Technologies like reverse osmosis promise to purify tap water, offering reassurance against potential exposure to harmful chemicals or carcinogens.

Reverse Osmosis: A Technological Marvel

Reverse osmosis (RO) emerges as a cutting-edge solution in our comprehensive water treatment arsenal. This advanced technology operates on the principle of selective filtration, effectively eliminating various contaminants present in the city’s water supply.

Contaminant Elimination:

Reverse osmosis utilizes a semi-permeable membrane that acts as a barrier, allowing only water molecules to pass through while blocking impurities such as nitrates, arsenic, lead, chromium 6, and other contaminants found in Phoenix Valley’s water. This selective filtration ensures the delivery of purified water for consumption.

Pressurized Filtration Process:

The RO system applies pressure to the water, forcing it through the specialized membrane. This pressure-driven process facilitates the removal of microscopic particles, dissolved solids, and unwanted substances, delivering water that surpasses regulatory standards.

Comprehensive Purification:

From common impurities to emerging contaminants, reverse osmosis excels in providing a comprehensive purification solution. It effectively addresses the concerns raised in the water quality analysis, assuring residents of a reliable and efficient method to enhance the safety of their drinking water.

Customized Filtration:

AC by J tailors reverse osmosis systems to the unique composition of water, considering specific contaminants identified in the city’s water quality reports. This customization ensures an optimized filtration process, maximizing the removal of potential health risks.

Reverse osmosis technology employed by AC by J not only meets but exceeds expectations in purifying water. By investing in this innovative solution, you take a proactive step towards safeguarding your family’s health.
