The Raton Basin which straddles the Colorado/New Mexico border has seen intense natural gas drilling and production in the past two decades. In 2008, a homeowner near Trinidad, Colorado, who was having his water well tested learned that it was contaminated by a chemical known as "Tert-butyl alcohol" or "TBA." TBA is a man-made subtance found in many household items such as perfumes, cosmetics and paint removers. But one place it shouldn't be found? Underground.
