A plating company that dumped thousands of gallons of cyanide-laced waste water into the Los Angeles sewer system pleaded guilty.
The water in the Los Angeles sewer system is contaminated.
It is definitely correct because the cyanide-laced waste definitely mixed with the rest of the sewage system in LA, and so the water is now contaminated. I think it fooled the system because the system cannot tell whether the cyanide-waste is a contaminate or not.
