Crews responded to a chlorine chemical leak at around 8:30 p.m. last night outside the wastewater treatment plant near the Market Street Bridge in Steubenville.

Officials said no chlorine made it to the main wastewater treatment tanks or into the Steubenville-area water table. Chlorine did make it to the intermediate filtration system and officials are assessing the damage to the microbes that clean the wastewater.

Officials are looking where this leak came from and the EPA has been notified.
