Which of the following would be considered an exempt domestic well?

A domestic well is generally defined as a well used for a single-family dwelling or household, and there are specific criteria regarding its pumping capacity that can determine whether it is exempt from certain regulations. In Arizona, an exempt domestic well is typically one with a maximum pumping capacity of 35 gallons per minute or less. This threshold is established in regulation to delineate which wells can operate without extensive permitting or regulation, thereby simplifying access to groundwater resources for residential use.

The significance of the 35 gallons per minute capacity lies in the need to balance groundwater extraction with sustainable management practices. Wells that exceed this limit may have higher rights and need to adhere to more stringent guidelines, as their operation could potentially impact neighboring water users and the overall water table.

The other options suggest larger capacities or less specificity regarding the usage of the pump. For instance, a pump with a capacity of 50 gallons per minute exceeds the limit for exemption. Similarly, stating that any size pump used for domestic use is exempt fails to recognize the critical threshold set by legislation, and claiming exemption based on general notice of intention to drill does not meet the specific criteria for exemption either. Thus, the correct choice reflects the precise regulations designed to manage domestic water usage effectively.
