York city officials are working on a way to remove the rotten egg smell from the city's new well field.
Officials began to receive complaints about the smell from residents when the new well water was added to the city system.
They say the smell is caused by naturally occurring bacteria feeding on the naturally occurring sulfate in the water. According to officials, that process creates a gas that evaporates quickly from the water, but leaves behind the odor.
Previous efforts by the city to remove the odor failed, so they had to stop using that water. Now the city council intends to hire Utility Service Group to treat the four wells.
Cleaning, inspections and testing of the wells is expected to begin Nov. 1.
