Gas drilling came to southern Colorado's Raton Basin in the late 1990s, and along with it heavy traffic, noise—and what many locals believe—contaminated water caused by industry.

The state investigated the matter and published a report suggesting TBA was naturally occurring among other explanations. Now the case is closed and the report—not only leaves more questions than answers—it leaves residents left high and dry—with water they feel they dare not drink.
