A chlorine leak Tuesday afternoon at Picatinny Arsenal was brought under control with minimal spread into the air.
A caller reported smelling an odor of chlorine in the area shortly after 1:30 p.m., according to Public Affairs Specialist Eric Kowal.
Picatinny Arsenal Fire & Emergency Services quickly responded. Members of the Morris County HAZMAT team also were called to the scene as a precaution after initial reports suggested the possibility of a chemical spill.
However, authorities determined that there was only a small leak and no actual spill, Kowal said.
"There was a small leak in a supply unit for one of our two water treatment facilities, but the amount was negligible," he said. "No one had to be evacuated or treated, and at no time did the leak pose a threat."
Firefighters and emergency responders were still on the scene as of 4 p.m., but by that point, the leak was said to be fully contained.
