Heap Leach Draindown Estimator (HLDE)
Why should industry need to spend $100,000 on draindown modeling for heap leach pads for bonding purposes? There should be a method to simplify the modeling while still obtaining results that are sufficient for bonding purposes.

Not All Contamination Comes from Mining Operations
The former International Smelter & Refining Company smelter (IS&R) produced copper, lead and zinc for 70 years. The site was listed on the NPL in July 2000. One of the Agency concerns was that the smelter was responsible for elevated nitrate and arsenic concentrations found in wells at a nearby town.

Response to Selenium Contamination at Phosphate Mines in Southeastern Idaho
Selenium contaminated vegetation and surface water related to phosphate overburden disposal was discovered in southeast Idaho in 1997. Shortly afterward, phosphate mining companies and regulatory agencies joined in response to the potentially widespread problem throughout the phosphate mining area.

Integration of Surface Water Management with Mitigation of Groundwater Impacts at a Proposed Phosphate Mine Overburden Facility
Environmental impact evaluation of proposed phosphate mine overburden fills at theJ.R. Simplot Smoky Canyon Mine, in Southeastern Idaho indicated that leaching of the overburden by infiltrating precipitation could potentially contaminate local groundwater with selenium.
