Black water in Crystal City, Texas
Crystal City's water turned black because they went too long in cleaning out the water tank. It had zero to do with oil. The city has a long an storied tradition of corruption. Several years ago in a previous scandal a city official had bypassed his water meter by hooking his house up to a fire hydrant. It was not even a cleverly disguised theft.
Crystal City's woes continue to grow after the mayor, city manager and other officials were arrested and accused of bribery and conspiracy.
