Signs warning of contaminated water were being removed from The Hook area.  They were put up after a weekend spike in E. coli levels in effluent discharged from the Hood River Wastewater Treatment Plant.  New Hood River Public Works Director Rich Rice told City Councilors Tuesday evening that water samples showed the discharge was back within Oregon Department of Environmental Quality limits.  Rice adds a new ultraviolet system is being installed in the plant to help reduce these kinds of issues.  That should be operating in a few weeks.  Rice said an investigation in to what may have caused the spike is underway.  There was a similar spike in September of 2021.
