Fort Worth Star-Telegram, Nov. 25, 2007 This report about industrial pollution in Midlothian mentions a study published in 1995 by the late Marvin Legator, an environmental toxicologist at UTMB. The study found three times more respiratory illnesses in Midlothian - home to most of Ellis County's industries - than in Waxahachie a few miles away. The study also found that the rate of cancer deaths in Ellis County was consistently higher than the rate in neighboring Tarrant County.
