Expert Testimony

For nearly a decade, SSP&A assisted with the development and implementation of long-term management of contaminated groundwater at the Anaconda Copper Mine Site in Lyon County, Nevada.

SSP&A was initially retained to provide expert review and evaluation of hydrologic, hydrogeologic, and geochemical conditions at the former Leviathan Mine Site, and to assess the sources of impacts of mining-related residues on groundwater and surface water.

For over 10 years SSP&A consulted to the NYSDEC spills department, evaluating and simulating the fate and remediation of fuel spills at multiple sites.

SSP&A was retained to develop a groundwater transport model that would explicitly account for the long-term fate of arsenic and boron in aquifers underlying the Coronet Industries Alternative Site, located in Plant City, Florida.

To address concerns regarding groundwater/surface-water interactions and potential Rio Grande Project Supply impacts, SSP&A provided expert hydrogeologic support in the evaluation of the Tulla Resources application and developed possible strategies for offsetting any potential impacts.

To assist the State in their management of water resources in the Carlsbad Basin, SSP&A developed a graphical user interface for evaluation of water rights transfer applications which integrates an existing superposition groundwater model and advanced applications of the Glover-Balmer and Theis equations for analysis of locations outside the active extents of the groundwater model.

SSP&A developed and calibrated a highly-detailed and refined historical groundwater flow model of the Lower Rio Grande Basin.

SSP&A provided expert services for the State of New Mexico, New Mexico Environment Department (NMED), and members of the Navajo Nation in lawsuits related to a mine blowout at the Gold King Mine in Silverton, Colorado.
