The go-ahead from state regulators has been given to a Dallas-based company that allows them to bury low-level radioactive waste near the Texas, New Mexico border.

The Texas Commission on Environmental Quality sent a letter to Waste Control Specialists today confirming the dump site was up to specifications. This comes after a year long effort by the company for approval, as environmental groups across the nation fought to preserve the geology of the site.

Some were concerned about the contamination of nearby ground water sources. The dump site, about 360 miles west of Dallas, will hold low-level radioactive waste from 38 states.
