Chandler Soil Testing & Brownfield Cleanup Rules

Environmental Protection Arizona 4 Minutes Read ยท published February 09, 2026 Flag of Arizona

Chandler, Arizona property owners and developers must follow local and state procedures for soil testing and brownfield cleanup when redevelopment or construction may encounter contaminated soils. This guide summarizes which city divisions and state programs typically apply, what permits or submissions are commonly required, how enforcement and appeals work, and practical action steps to begin testing or a cleanup process in Chandler.

Overview of Authority and When Testing Is Required

Soil testing and remediation in Chandler commonly involve coordination between City of Chandler planning and building divisions and state cleanup programs. Developers should order site assessments when prior land use suggests contamination (gas stations, industrial sites, dry cleaners) and before grading, digging, or change of use that requires a building permit. Official program guidance is maintained by the City of Chandler and by the Arizona Department of Environmental Quality (ADEQ) and the U.S. EPA for brownfields and voluntary cleanup programs.City planning & development[1] ADEQ Brownfields and cleanup programs[2] EPA Brownfields program[3]

Start a Phase I environmental site assessment if the site has a history of potential contamination.

  • Site assessments: retain a qualified environmental consultant to prepare Phase I and, if needed, Phase II reports.
  • Permit filings: submit required documentation with your building or grading permit application to City of Chandler Planning & Development or Building Safety.
  • State notifications: if contamination is identified, coordinate with ADEQ or the ADEQ Voluntary Remediation Program for closure options and state-level approvals.
