Review of New Groundwater Quality Information and Potential Impact on Geochemical Pit Lake Model

Document ID:

Year Published: 
2015
Summary: 

Additional water quality information was submitted by Rosemont Copper Company to the Coronado National Forest on January 17, 2015, representing the most complete database of groundwater quality available (Rosemont Copper Company 2015).

As part of the review conducted in the Supplemental Information Report to evaluate whether these additional data would change conclusions in the FEIS, the groundwater quality samples for wells PC-1 through PC-8 were evaluated and compared to the average concentrations used as ambient groundwater quality inputs in the geochemical pit lake model (Tetra Tech 2010). The samples used as inputs to the geochemical pit lake model were collected during the first round of groundwater sampling in 2008. Additional rounds were conducted in 2012 and 2014 and these results were part of the information provided by Rosemont Copper Company in January 2015.
