In remarks to the Legislature in January, Roth described the Hilo plant’s condition as “really terrible.”
Unless investments are made to fix the problems, the wastewater plant could turn into Hawaii’s “next Red Hill,” Roth said. He was referring to the Navy’s underground storage fuel facility on Oahu where fuel leaks contaminated […]
