Phytostablization of Mine Tailings with Compost-Assisted Direct Planting
Research Brief - July 2016
Amending mine waste with compost is a viable and promising alternative to the expensive process of covering an entire site with a thick soil or rock cap followed by seeding, according to research from the University of Arizona Superfund Research Program (UA SRP) Center. A recent field study at the Iron King Mine and Humboldt Smelter Superfund site showed that adding amendments and seeds led to establishment of native plants and sustained growth on mine tailings over 4 years.
SRP researchers quickly inform communities near Colorado mine spill
Environmental Factor - October 2015
Following the Aug. 5 Gold King Mine spill of about three million gallons of mineral-polluted water into a tributary of the Animas River in Colorado, researchers from the University of Arizona (UA) Superfund Research Program (SRP) moved quickly to inform affected communities about potential health and environmental risks.
