Guam - Guam Waterworks Authority Contractors discovered chlorine inside one of the old gas tanks located at the Northern Wastewater Treatment Plant last night. According to GWA Spokesperson Heidi Ballendorf as a result the surrounding area is being evacuated today to facilitate its removal.

Last month GWA's contractor, Veolia Water Guam, LLC began the removal of several chlorine gas tanks as part of an ongoing cleanup and maintenance project. Ballendorf says this is the seventh tank to be removed and so far the only one in which chlorine was detected inside.

The Guam Fire Department is on scene monitoring the tank's removal.
