Raw sewage leaking into Nogales wash is still being investigated for its cause

NOGALES, AZ — By taking a close look at the Nogales wash, the water is visibly clear.

The Arizona Department of Environmental Quality says that may be because the utility in Nogales, Sonora has begun chlorinating the water to kill any bacteria.

The department of environmental quality says on January 16, a wastewater treatment plant in Sonora began having issues resulting in raw sewage leaking into a tunnel under the border and eventually into the wash.

Since discovering the leak, the US and Mexico sections of the International Boundary Water Commission have been in contact with the utility in Sonora to determine the cause.

The department of environmental quality advises people to avoid contact with the wash in this area and make sure pets stay away.

Officials says the flow is intermittent and the USGS gauge in the area is recording normal readings.
