The Georgia Water Coalition on Wednesday announced its annual “Dirty Dozen,” highlighting threats to Georgia’s water. The list includes three local coastal issues: offshore drilling, pollution in the Altamaha River and continued risks to coastal groundwater. And it gave a special shout out to the state’s stalling of the Palmetto Pipeline, adding it as a “Clean 13” to the dirty dozen. “It is not a list of the most polluted water bodies in our state,” said Juliet Cohen, executive director of Chattahoochee Riverkeeper, a member of the coalition.
