North Pole Refinery - Project Home



The discovery of sulfolane in drinking water wells in 2009 near the North Pole Refinery, about 15 miles east of Fairbanks, has led to an extensive groundwater investigation. Flint Hills Resources of Alaska, owner of the refinery, responded quickly by providing affected residents with alternate drinking water. Sulfolane is an emerging contaminant, therefore, the long-term health effects from exposure through drinking water are not yet understood. The groundwater plume is approximately 2 miles wide, 3.5 miles long and over 300 feet deep, making it one of the largest in the state, with many private properties impacted. Approximately 400 alternate drinking water supplies have been provided to the affected properties. For additional details, see Frequently Asked Questions.
