198 oil and gas wells found abandoned near Carlsbad Caverns

Almost 200 oil and gas wells sit abandoned within a 30-mile radius of Carlsbad Caverns National Park.

The caverns, which contain a complex system of underground caves, filter local groundwater sources and could be susceptible to contamination from industrial sources like orphaned wells.

A study conducted by the National Parks Conservation Association ranked Carlsbad Caverns as the national park or monument with the second-most nearby abandoned wells in New Mexico.
