west dallas lead smelter

Does anybody know of anyone who worked at the lead smelter in west dallas, or in cadillac heights? I am doing a research project on these smelters,a dn the contamination that they left behind in the air and soil. If anybody has any memories, or leads to interesting people to discuss this with, please call me. 214-906-4152. Or email me: leo12086@gmail.com

Thanks,
Laura
