AZ HB2271

Amends section 45-105, Arizona Revised Statutes, to modify the Department of Water Resources director's duties regarding groundwater basin assessments.

Requires the director to include specific technical measurements in five-year water supply and demand assessments for each groundwater basin, including average depth-to-static level, bedrock depth, and total groundwater volume available.

Mandates assessments include data on active index wells (total number, average distance between wells, and geographic density) to measure groundwater monitoring coverage across each basin.

Requires assessments to track groundwater availability in years at current depletion or recharge rates and document stormwater and groundwater recharge project activity and volumes for the preceding five-year period.

Maintains existing requirement to complete assessments for all 51 groundwater basins and active management areas at least once every five years, with director able to contract outside entities to conduct assessments.
