Yuma biosolids dispute remains unresolved after July 23 town hall

Five days after a July 23 town hall in Yuma, the dispute over AgTech’s biosolids operations remains unresolved. Residents raised concerns about flies, odors and alleged effects on animals and loved ones, but the meeting did not produce a shutdown order, enforcement action or final regulatory decision.

The town hall was held at the Yuma Civic Center from 6 p.m. to 7:30 p.m. and ran longer than scheduled because many questions remained unanswered, according to KYMA’s report. The event was hosted by Arizona Attorney General Kris Mayes.

Residents described serious concerns

The Civic Center was packed with Yuma-area residents, including longtime residents and newcomers. Several people told officials that flies had become unbearable and said they believed the problem was affecting animals or making loved ones ill.

Those accounts are resident allegations, not established scientific or regulatory findings. The town hall did not determine whether AgTech’s operations caused flies, odors, illness or animal problems.

AgTech operations manager Kevin Good urged residents to examine available research and said rumors should stop. In earlier public comments reported by KAWC, the company said its handling of treated biosolids is safe and that the material is used to improve agricultural soil.

County authority is limited

Yuma County says it cannot unilaterally close the operation because key decisions involving biosolids permitting and State Trust Land leasing are controlled by state agencies. That distinction matters for residents seeking immediate action from county officials: a county meeting or complaint does not automatically change the operation’s legal status.

The county also reports that AgTech’s lease is in holdover status. In practical terms, that means the lease is continuing under an existing arrangement while its status is addressed. It is not the same as a newly approved long-term lease, and it is not a shutdown order.

According to the county’s biosolids information page, recent inspections at six AgTech sites found no fly larvae. The county also points to earlier research identifying agricultural produce composting and decomposition as major contributors to countywide fly populations. Those findings provide context, but they do not by themselves disprove residents’ reports or establish the cause of any particular health complaint.

State study will take years

Arizona’s 2026 Senate Bill 1336 created a Biosolids Study Committee after the bill was signed by the governor on June 22. The committee is directed to review biosolids use for agricultural and other purposes in Arizona, including use on State Trust Land, and to evaluate the policy of accepting biosolids from other states.

The Arizona Department of Environmental Quality’s legislative summary says ADEQ, the Arizona Department of Agriculture and the State Land Department will provide meeting space, staff and support services to the committee. The committee’s report and recommendations for possible rule or legislative changes are due by December 31, 2028.

That deadline means the state policy process is only beginning. For Yuma residents, the next meaningful developments are likely to come from additional inspections, state permitting decisions, State Land Department lease activity and the committee’s future meetings and recommendations.

For now, the town hall gave residents a public forum but did not resolve the underlying dispute. The documented inspection information, the company’s position and the residents’ accounts remain separate pieces of an issue that still requires further scientific, regulatory and policy review.
