Jennifer Hall-Massey knows not to drink the tap water in her home near Charleston, W.Va.
In fact, her entire family tries to avoid any contact with the water. Her youngest son has scabs on his arms, legs and chest where the bathwater -- polluted with lead, nickel and other heavy metals -- caused painful rashes. Many of his brother's teeth were capped to replace enamel that was eaten away.
Neighbors apply special lotions after showering because their skin burns.
