    Buffelgrass Complaints

    PDEQ, in coordination with other state and local agencies, is committed to addressing the serious threat posed by the spread of buffelgrass in the Sonoran Desert. The Pima County Board of Supervisors has recently adopted an ordinance to facilitate this effort. Please read the provided buffelgrass information prior to submitting a complaint by phone (call (520) 724-7400 and ask to speak to a Complaint Coordinator) or through the online Buffelgrass Complaint Form.

    Mold Complaints

    PDEQ does not have the authority to investigate or address mold concerns inside residences or businesses in Pima County. It is the property owner’s responsibility to determine if mold is present and if so, to properly remediate it. There are many mold remediation businesses you can hire to determine if mold is present in your home and to clean up the mold, if you are unable to do it yourself.

    In addition, the U.S. Environmental Protection Agency has information and resources on their website that might be helpful, including ways to prevent and control mold, guidelines for cleaning up mold, and general information on mold and other indoor air quality topics.
