WILLISTON, N.D. (AP) -- An early morning lightning strike caused a fire at a saltwater disposal well near the northwestern North Dakota town of Ross.
State Health Department environmental geologist Kris Roberts says lightning hit the well owned by Fort Worth, Texas-based Basic Energy Services at 4:30 a.m. Friday. He says fires were still burning as of 7:30 a.m. and that the site likely will be destroyed.
Roberts says one worker was on site at the time of the strike but was not injured.
Saltwater is a byproduct of oil production. It is between 10 and 30 times saltier than seawater and is disposed of in special wells.
