EPA v. KENNECOTT SOUTH ZONE SUPERFUND SITE

Case summary

THE KENNECOTT SOUTH ZONE SITE IS COMPOSED OF SURFACE AREAS CONTAMINATED BY MINING WASTES WHICH MIGRATED FROM SOURCE AREAS INTO DOWN GRADIENT CITIES AND SUBSURFACE AREAS CONTAMINATED BY ACID LEACHATES FROM THE MINING DISTRICT. THE GROUNDWATER CONTAMINATION WAS CAUSED BY THE RELEASE OF ACID MINE DRAINAGE AND ACID LEACHATES FROM MINING ACTIVITIES IN THE BINGHAM CANYON MINING DISTRICT. THE REMEDY HAS BEEN COORDINATED WITH THE STATE OF UTAH'S NATURAL RESOURCE DAMAGE (NRD) SETTLEMENT TO ARRIVE AT A COMPREHENSIVE SOLUTION TO GROUNDWATER CONTAMINATION IN THE VALLEY. EPA EXPECTS THE COMBINED CERCLA/NRD ACTIONS TO COST ABOUT $300 MILLION.
