Progress is ongoing in repairing the partial breach in the International Outfall Interceptor (IOI).
Officials ask that the public refrain from entering this area to allow agencies representatives to conduct their surveys and for the safety of the employees working in the area.
The Nogales International Airport has issued a Notice to Airmen (NOTAM) for a one nautical mile around the worksite. Officials have requested that drone use be restricted in the areas crews are working.
Santa Cruz County Health Services and the Arizona Department of Health Services are advising the public to stay out of the Nogales Wash and the Santa Cruz River. Even in the absence of untreated wastewater, stormflows are typically high in pollutants that can be harmful to human health such as bacteria and pathogens. Water near and downstream of the IOI partial breach is of particular concern and should be avoided.

Arizona Department of Environmental Quality (ADEQ) continues to sample daily along the Santa Cruz River.
The Department of Agriculture shares the concerns of livestock owners and farmers in the region. Until there is more information about the extent of the situation, it is recommend not using water from the Santa Cruz River to water food crops or gardens. Livestock should not be in the river or drinking from it.
