Waste products from Pharmaceuticals

I saw waste chemicals drained into the bay area. That company used Alcohol 70% and 90% unlimited and all drained to the bay area.
When I complaint to the Safety Department of that company, I was fired.
I want to safe enviroment especially sea animals.
How can we know how many tons of waste chemicals those Pharmaceutical companies drain to the bay everyday?
We need to stop that action in proper way.
