The Arizona Legislature convened on June 23, 2025, to address significant environmental concerns regarding groundwater contamination following the burial of over two million chickens at Hickman’s Valley Farm. The meeting focused on the state’s decision to issue a waiver allowing this burial, which has raised alarms among local residents and environmental activists.

The discussion began with legislators expressing their apprehensions about the potential impact on groundwater supplies. A state representative highlighted that the waiver was accompanied by a $1.5 million investment to facilitate the burial process. This financial support, coupled with the waiver, prompted questions about the adequacy of state measures to protect Arizona's unique aquifer systems, which are designated for drinking water use.

Officials from the Arizona Department of Environmental Quality (ADEQ) defended their actions, stating that the burial method was approved by the U.S. Department of Agriculture (USDA) and is commonly used across the country. However, they acknowledged that Arizona's specific water concerns necessitate a more cautious approach. The ADEQ explained that the decision to allow the burial was made under emergency conditions, as the chickens had already been depopulated and were decomposing rapidly in extreme heat.

The waiver granted a 90-day period for assessing the hydrological conditions of the site, during which the state would determine whether an Aquifer Protection Permit (APP) would be required. Legislators questioned the rationale behind initially permitting the burial without a thorough understanding of the groundwater depth and soil conditions. ADEQ officials clarified that the urgency of the situation necessitated immediate action, but they later mandated that no further burials occur until a comprehensive assessment could be completed.

As the meeting progressed, concerns were raised about the lack of a liner requirement in the temporary waiver, which could potentially allow contaminants to seep into the aquifer. ADEQ representatives stated that if the assessment indicated a risk of contamination, they would require remediation measures, which could include pumping and treating groundwater to prevent off-site migration of pollutants.

The meeting concluded with a commitment from state officials to closely monitor the situation and ensure that the necessary steps are taken to protect Arizona's groundwater resources. The outcome of the ongoing assessments will determine the future of the burial site and the potential need for further action to safeguard public health and the environment.
