"The low-income neighborhood of older wood-frame homes in West Dallas is a far cry from the suburb of newly built brick houses in Frisco 30 miles to the north. But the two North Texas communities share a bond: Both were contaminated by industrial lead for nearly half a century."
"The 1984 closure of RSR Corp.’s smelter, where used car batteries were recycled, was just the beginning of West Dallas’ struggles with lead. Contamination from the smelter still exists there today, residents say. That raises questions about the road ahead for Frisco, where cleanup is just starting at the Exide Technologies smelter that shut down Nov. 30."
