The tailings would fundamentally change the physical and chemical characteristics of the lake, raising the lake bed by 50 feet and expanding the area from 23 to 60 acres. Coeur Alaska proposed to temporarily re-route nearby streams around Lower Slate Lake until they could purify the water and re-introduce the natural flow patterns.

The Johns Hopkins study involved two vans that drove the same routes repeatedly over the course of a month last year. Researchers used instruments that measure gases in real time as they flow ...
Permits typically require reporting of wastewater flow and the results of one or more chemical tests corresponding to the effluent limitations. Typical monitoring parameters include pH, biochemical oxygen demand (BOD), total suspended solids (TSS), nutrients (nitrates and phosphorus), various toxic pollutants, temperature, etc.
