What can result from a well categorized as non-exempt?

A well categorized as non-exempt requires the owner to obtain a withdrawal permit before extracting groundwater. This means that the usage of water from such wells is subject to government oversight and regulatory processes, which are designed to ensure sustainable water use and protect water resources.

In contrast, exempt wells, often related to smaller withdrawals, do not require such permits and can be accessed with fewer restrictions. Therefore, non-exempt wells are specifically defined by their requirement for permits, ensuring that all water extraction adheres to state regulations aimed at managing and conserving Arizona's water supply.

The other choices reflect scenarios that do not apply to non-exempt wells, as they indicate either restriction-free use, regulatory exemption, or immediate enhancements to irrigation rights, none of which align with the regulatory framework governing non-exempt well operations in Arizona.
