Water Quality Statement
There is a complex and extensive framework in place to ensure clean, safe drinking water is served by every public water system in Arizona. Protection of drinking water quality starts with an assessment of the drinking water source quality and continues through regulations that govern water system design and construction. Finally, drinking water quality is assured through scheduled tests required of all public water systems for a wide variety of potential contaminants. As a result of these regulations and continued testing, drinking water supplies in the United States are among the cleanest and safest in the world.
The Water Utility operates two potable water systems. The Oro Valley Water Service Area (OVWSA) that has a Public Water System Number of AZ0410164. It also operates a potable system that is not located within the Town boundaries, known as the Countryside Water Service Area (CSWSA) that has a Public Water System Number of AZ0410175.
Over the course of a year the Utility collects hundreds of water samples from approximately 19 “point of entry” sites. These sites include groundwater wells, reservoirs and pumping stations. The Utility also samples from 58 “sampling stations” located in neighborhoods throughout the water distribution system specifically selected to represent the water quality that is delivered to our customers. Lead and copper samples are taken from 50 private residences within the Oro Valley area. The Utility provides all water quality testing results to the Arizona Department of Environmental Quality (ADEQ) and works closely with that agency to ensure all federal and state standards are met.
The Utility’s State certified water operators are legally responsible for the health and safety of our customers. The operators meet this responsibility by maintaining a daily vigilance over the system’s production, distribution, and water quality. All our Operators are licensed and attend continuing education and training through Personal Development Hours required by ADEQ. This also benefits our community and adds value to the Water Utility. Additionally, comprehensive emergency plans have been developed to ensure an immediate response to any adverse water situation. The Town’s water system is in full compliance with all State and Federal regulations.
