WQARF Registry

The Water Quality Assurance Revolving Fund (WQARF) Registry lists sites in Arizona that may pose a risk to public health or the environment due to hazardous substances and have current or planned investigation and cleanup. Currently, there are 38 sites on the WQARF Registry | Download WQARF Registry >

Based on the type of contamination, the contamination’s location and the number of people that may be affected, a registry site’s score can reach a maximum of 120. Whether the site is currently being remediated or investigated, ADEQ takes steps to identify the contamination and prevent exposure.
