NOGALES, Ariz. (AP) — Authorities say a broken pipe has resulted in untreated wastewater getting into the Nogales Wash.

Officials with the Nogales public works discovered the broken pipe on Tuesday.

They say a dislodged section of cement partially sheared the pipe below the waterline, causing the discharge of the wastewater into the wash.

The breach happened in the International Outfall Interceptor, which transports wastewater from both sides of the border to the Nogales International Wastewater Treatment Plant.

Santa Cruz County health services officials say the location of the partial breach is in a sparsely populated area of the county.

They are advising people who live in areas where there is water running in the wash to keep out of those areas.

It was unclear Wednesday when the pipe would be repaired.
