Project Description

The Pilgrim and Magma mine are non-operational and have a notable amount of tailings piles left behind. This project will combine testing and extensive research to determine the best way to stabilize the tailing piles to mitigate migration to nearby communities. There will be a site visit where samples will be collected in order to analysis and design the best mixture needed to stabilize the tailings piles. A series of testing will be done to ensure the designed mixture is efficient and effective.

Project Constraints

The project constraints include having the solidification material pass the leachability test where the contaminants must be under the EPA's allowable limits for arsenic and lead.

US EPA Allowable Limits:

Arsenic = 5 ppm

Lead = 5 ppm
