The impact on the aquatic environment of industrial effluent has to be determined. ETP (Effluent Treatment Plant) has a limit on discharge after treatment.

I would start by determining the mixing zone concentration: USEPA Technical Support Document Water Quality Based Toxics Control

Then Look at USEPA Guidance on determination and use of Water-Effect Ratios for metals.
