Students from Port Chester Middle School and JFK Elementary School were evacuated about 10 a.m., but classes had resumed by late morning.
Port Chester Police Chief Richard Conway said Con Edison crews responded to the area and determined the odor was likely caused by a minor gas leak or sewage line backup. Utility and emergency crews continued to investigate, Conway said.
More than a half-dozen calls were made from area residents along Bowman Avenue, Southview Street, Olivia Street and South Ridge Street.
