Meet Our Science Fair Winners
 (2000)

PitWatch Issue Volume 5, Number 1

The Committee awarded $50 savings bonds to each of these grade school students and a $250 savings bond to the high school winner. Their science fair projects all explored important topics related to the Berkeley Pit. Congratulations, and keep up the good work! The Committee will offer awards again at the 2001 Science Fair, and students are encouraged to choose projects related to the Pit for next year’s competition.

PitWatch Volume 5, Number 2

In July 2000, Montana Resources suspended mining operations. The suspension has had a direct impact on the Berkeley Pit water levels and efforts are underway to deal with the problem.

The immediate concern is treating the Horseshoe Bend water, which had been diverted away from the Berkeley Pit since 1996. Based on data from July 1 to September 30, 2000, about four to five million gallons per day is entering the Pit from the Horseshoe Bend flow. Montana Resources had been treating this water as part of its mine operations.
