This case involves multiple residents of a neighborhood that allegedly contracted neurological disorders due to toxic exposure to chemicals. Residents were diagnosed with toxic encephalopathy, schizophrenia, and tremors, among others. The neighborhood in question borders a natural gas power plant. The residents observed changes in their water quality over the course of several months. The running water in their homes had become foamy and grey in color. A soil test detected elevated levels of a number of toxic chemicals and blood tests of some of the affected residents revealed elevated levels of the same chemicals. An expert in neurotoxicology was sought to opine on the link between toxic chemical exposure and neurological disorders.
