Environmental group Chattahoochee Riverkeeper threatens to sue Atlanta over unsafe wastewater plant, citing high E. coli levels in the river.

Environmental group Chattahoochee Riverkeeper is threatening to sue the city of Atlanta for an allegedly unsafe wastewater treatment plant, linked to high E. coli levels in the Chattahoochee River. The group claims the city's proposed corrective action plan is insufficient, and will file a federal lawsuit if the issues aren't resolved. High E. coli levels can lead to serious health issues, particularly for vulnerable populations.
