Municipal effluent chlorination and dechlorination ...
Where disinfection is required and chlorine is used, the regulation requires the residual chlorine is to be limited to 0.01 mg/L (10 g/L) (Waste Management Act - 1999 Municipal Sewage Regulation(MSR) - Part 8: Effluent disinfection). Ensuring that this level is met is one concern of the Georgia Basin Ecosystem Initiative (GBEI).
