Abstract:

Soil and groundwater contamination at the Montana Post & Pole site in Butte, Montana, one of the nation's oldest Superfund sites, has developed into one of the most significant environmental issues. Product thickness was observed more than 5 feet in one groundwater monitoring well near the apparent source. the extent of the contaminant plume is about 1,350 feet long and 130 feet wide near the source area. A previously installed passive oil recovery system, comprised of recovery trenches and infiltration galleries, was installed as a temporary remedial measure in 1985. The newly installed product recovery system has recovered approximately 35 gallons of free-phase product daily since January 1993 and has surpassed the approximate 11,000 gallons recovered in seven years by the previous passive system.
