Arizona House Passes Bill To Answer Important Questions About Arizona’s Water
By Daniel Stefanski |
How much water does Arizona currently have? That’s the question on the mind of Arizona lawmakers this legislative session.
Last week, Arizona House Republicans revealed that a small group of legislators had previously sent a letter to the Arizona Department of Water Resources (ADWR), asking the agency “to provide basic information on the following details related to Arizona’s rural groundwater basins:
- The average depth-to-water level in each basin
- The maximum depth of each basin
- The average depth of each basin
- The total volume of groundwater in each basin
- The number of index wells in each basin.”
The letter, which was authored by State Representative Gail Griffin, Senator Tim Dunn, and former Senator Sine Kerr, was transmitted to ADWR on December 23, 2024.
Speaking about the reasoning behind the letter to ADWR, Representative Griffin said, “The intent was to give Arizonans a better understanding of the groundwater supply beneath their feet. For the last two years however, none of the Department’s assessments have included this basic information – such as ‘how much water do we have’ and ‘how long will that water last.’ This information is a fundamental component of the ‘supply’ side of the ‘supply and demand’ equation and needs to be included in each of the Department’s five-year ‘Supply and Demand’ Assessments.”
According to the press release issued by House Republicans, ADWR “provided a preliminary response to the December 23 letter, stating the number of active index wells in each basin and the maximum depth of each basin at its deepest point.” The response shared that the “Wilcox and Gila Bend groundwater basins are 4,800 feet deep at their deepest point.” However, as the release highlights, “The Department has yet to provide the total amount of groundwater that is available to each of these depths.”
Representative Griffin is not at all satisfied with ADWR’s incomplete answers. She said, “Just because you drill a well does not guarantee that there will be one hundred years’ worth of water. Republicans and Democrats both agree we need to know how much water is available in order to make informed decisions on critical groundwater policy. It’s also essential to our ability to plan for the future. How are we supposed to plan if we don’t know how much water we have?”
With these questions in mind, Griffin introduced a bill (HB 2271) this legislative session “to update the 5-year Supply and Demand Assessment statute and require the Department to include this information in its reports, moving forward.” If the proposal was signed into law, it would “provide critical answers to these basic questions, such as, ‘How much water do we have?’ and ‘How many years will that water last at the current rate of decline?’” Answering these questions would allow legislators to “plan to add new tools that work for rural Arizona, such as groundwater recharge, replenishment, and reuse.”
Focusing on her bill, Griffin said, “we understand that additional steps may be necessary to gather this information, but we also believe that taking these steps is a necessity to do our jobs effectively. I think the Department wants to make decisions based on science and that, if we give it the time and opportunity to gather this information, it will result in a better and more constructive dialogue for everyone.”
HB 2271 was approved by the Arizona House of Representatives last week.
