A chemical leak from an asphalt plant has contaminated the water supply in Corpus Christi, Texas. The city has warned residents not to drink or bathe in tap water. Even boiling the water will not make it safe. Residents are forced to purchase bottled water for drinking, cooking and bathing. The chemical that has leaked into the water supply is called Indulin. It is corrosive and can burn a person's skin if in concentrated amounts. It can also cause damage to internal organs if ingested. The chemical is classified as hazardous by the Occupational Safety and Health Administration. City officials eased some restrictions on tap water use Friday while workers flushed water pipes to clear away any traces of the chemical.
