Work continues on the International Outfall Interceptor (IOI) to fix a partial breach. The breach was discovered last week near the intersection of Old Tucson Road and the Nogales Wash.
Bank stabilization and other preparatory work is proceeding on schedule.
In the meantime, Public Health officials from Santa Cruz County and the State of Arizona advise people to stay out of the Nogales Wash and Santa Cruz River. Even in the absence of untreated wastewater, storm flows are typically high in pollutants that can be harmful.
