While the company may be following the law, it is clear they could dispose of their waste more safely and be more responsible stewards of the neighborhood. However, that would cost the company more money, and may affect profit margins, result in slower growth, and provide fewer jobs for the locals.
I believe that, if the company continued disposing of their waste unsafely, they would not be conducting their business with respect or integrity. The potential danger to health outweighs the risk of creating less jobs for locals
