Holly Peterson Presents on Water Quality


Assistant Professor of Geology Holly Peterson presented a paper on water quality at a research meeting in Santiago, Chile. The international event, April 20-25, was the 10th International Conference on Acid Rock Drainage and the International Mine Water Association 2015 Conference.

Holly presented “The Effects of Preferential and Matrix Flow and Water Residence Time on Seasonal Fluctuations in Mine Waste Rock Effluent Water Quality.” The peer-reviewed paper, co-authored with K. Ulrich Mayer and Roger Beckie of the University of British Columbia, has been published in the proceedings of the conference.

The study examined the flow and quality of water that emerged from three piles of rock at the Antamina Mine in Peru. Each pile – 36 meters by 36 meters and 10 meters tall – consists of a different type of waste rock from the mine. The mine, located about 4,500 meters above sea level in the Andes Mountains, experiences distinct wet and dry seasons.
