City of Mesa water customers who reside in the general area of Mesa Drive to the Eastern Canal between McKellips Road and University Drive may notice a subtle change in their tap water. This is due to a temporary increase in groundwater well pumping which causes millions of tiny air bubbles to form and the water to appear cloudy. The air bubbles are formed by a release of pressure and it may take several minutes for the air to escape. As it does, the water will clear from the bottom of the glass, upward. Leftover dissolved air can cause the water to sparkle or have small bubbles.
The increase in well water use is due to system maintenance and is expected to last until October 2013. Residents should be assured that Mesa's water is safe to drink and continues to meet and exceed stringent state and federal water-quality standards.
"Mesa Water’s distribution system is under pressure. Any air present is dissolved in the water until the pressure is released at the tap," Water System Superintendent Steve Ruppenthal said. "Dissolved air in the water is not harmful to people or plumbing or appliances."
