GARLAND, Texas - Late Sunday evening, Garland ISD acknowledged for the first time that the EPA has alerted the district of a potential environmental hazard. The hazard is related to the Globe-Union battery manufacturing plant. The EPA found elevated levels of lead near the banks of a creek outside the fence of Park Crest Elementary. Faced with an ill family member, Don Phillips began to wonder three years ago if it was connected to the old Globe-Union battery manufacturing site that used to operate near his family's home. A Facebook post he made quickly gained traction.
