Treatment Plant Odor Being Addressed

Residents living near Dubuque’s wastewater treatment plant soon might have a more pleasant experience when they head outdoors. Staff members at Dubuque Water & Resource Recovery Center plan to implement a pilot chemical injection program within the next two weeks to reduce the foul odors coming from the facility. Center Manager William O’Brien said the program will mix hydrogen peroxide in the wastewater treatment plant’s sludge tanks in order to bind sulfur compounds, which emit odorous gases when they break down. Once this is applied, nearby residents should notice an improvement in outdoor air quality.
