Buckeye Water Resources is committed to providing you with the best drinking water possible.

We are required by law to meet all drinking water standards established by the y the Environmental Protection Agency.

The EPA established the Clean Water Act (1972) and Safe Drinking Water Act (1974) to ensure everyone has clean, safe and reliable drinking water whenever they need it. Both the Arizona Department of Environmental Quality (ADEQ) and Maricopa County Environmental Services Department (MCESD) enforce these standards.

Our certified water operators sample water throughout the system daily and perform over 150 tests for new wells. They also work closely with the EPA, the Arizona Department of Environmental Quality and the Maricopa County Environmental Services Department to ensure all drinking water standards are met 365 days a year, 7 days a week and 24 hours a day.


Since Buckeye relies almost entirely on groundwater, we are well aware the Total Dissolved Solids (TDS) concentrations (typically calcium, sodium, arsenic and magnesium) that occur naturally in our water are not aesthetically (smell, taste, hardness) pleasing to customers.

The TDS concentrations are due to naturally occurring minerals in the ground where our wells are located. These minerals dissolve in the water and require reverse osmosis treatment for removal.

We could implement additional, expensive treatment processes to reduce the TDS, but these costs would then be passed on to you, our customer, which is not a cost effective option.

The EPA has only established a secondary standard for TDS, because it is not considered a risk to human health. The secondary standard was established as a guideline to assist public water systems with managing their drinking water for aesthetic considerations, such as taste, color and odor.  

Some other naturally occurring minerals, such as arsenic and fluoride, and nitrates (nitrates can be naturally occurring or man-made), do have a primary standard  set by the EPA, and our Water Resources staff tests regularly to ensure your drinking water is within the established limits.

Despite these challenges, Buckeye’s drinking water meets or surpasses all standards set by the EPA.
