A tank overflow in McHenry County led to the release of about 21,000 gallons of source water—salty, mineral-rich water drawn from underground—onto nearby cropland. The spill, reported by Murex Petroleum, occurred northeast of Glenburn on March 23. State environmental officials are now investigating and overseeing cleanup efforts. No immediate threats to drinking water have been reported. Ongoing updates are available through North Dakota’s public spill reporting system.
