WILLARD -- State officials say fuel oil from a Chevron pipeline spill at Willard Bay State Park is seeping into groundwater and making its way beyond containment booms.
Utah parks and recreation chief Fred Hayes tells KTVX-TV in Salt Lake City that containing and cleaning up the oil could now take weeks or months.
The northeast Great Salt Lake park was closed after the 20,000-gallon pipeline rupture was discovered March 18 at the bay off Interstate 84 south of Brigham City.
State water quality director Walt Baker says that once crews stop groundwater seepage, contaminated soil will be removed.
Gov. Gary Herbert has criticized Chevron's third pipeline leak in the last three years.
The company was fined more than $400,000 for the two earlier spills.
