<br />Susan A. Wyman, P.E., P.G.
<br />• Schwartzwalder Mine, Colorado - Developed an extensive water quality database and prepared time-series
<br />plots to evaluate geochemical evolution of surface water, groundwater, and the mine pool. Assisted in
<br />equilibrium geochemical modeling. Performed mass balance mixing models to predict mine water chemistry.
<br />• Schwartawalder Mine, Colorado - Designed and conducted a water quality survey to determine electrical
<br />conductivity, pH, and temperature along a 1.6-mile reach of Ralston Creek.
<br />• Schwartzwalder Mine, Colorado - Collected stream samples to investigate water quality above and below
<br />Schwartz Trend Crossing on Ralston Creek.
<br />• Schwartzwalder Mine, Colorado - Compiled and evaluated mitigation options for groundwater in alluvium and
<br />fill. Engineered HDPE pressure piping system for gathering and conveyance of alluvial groundwater to the
<br />water treatment plant. Designed HDPE gravity piping system for conveyance of treated water to engineered
<br />outfall on Ralston Creek.
<br />• Van Tuyl Ranch, Colorado - Provided pro bono services to City of Gunnison and Western State College for the
<br />water resources evaluation of the Van Tuyl Ranch Management Plan. Provided mentoring and equipment to
<br />Western State College students in monitoring well installation, development, and sampling.
<br />• Blackfoot Bridge Mine, Idaho - Designed baseline monitoring program for surface water. Conducted quarterly
<br />field sampling, evaluated data, and prepared summary reports in support of environmental impact analysis for
<br />an open pit phosphate mine, as a Yd party EIS contractor to the US Bureau of Land Management.
<br />• North Rasmussen Ridge Mine, Idaho - Evaluated potential geochemical impacts to surface water and
<br />groundwater from selenium and other constituents related to open pit phosphate mining, as a third parry EIS
<br />subcontractor. Tasks included the analysis of climatological data, developing pit wall runoff predictions,
<br />modeling unsaturated flow through capped backfill using UNSAT-H and HELP3, assisting in the development
<br />of a groundwater flow model using Modflow and MT3D to assess the potential migration of COPCs in
<br />groundwater, developing spreadsheet analytical models for surface water impact analysis, and preparing the
<br />Water Resources Technical Report for the US Bureau of Land Management.
<br />• North Rasmussen Ridge Mine, Idaho - Evaluated the site hydrologic systems and regulatory framework and
<br />prepared the mine's Surface and Groundwater Monitoring Plan for submission to the Idaho Department of
<br />Environmental Quality.
<br />Taylor Ranch Project - Designed and implemented baseline monitoring program for surface water,
<br />groundwater, and domestic wells. Developed database of historical and ongoing sampling results for water.
<br />soil, and air. Technical lead on water resource issues in public hearings and permitting applications for state
<br />and county environmental permits.
<br />• Lisbon Valley Mine, San Juan County, Utah - Located, designed, drilled, completed, and developed 5 industrial
<br />water supply wells capable of producing more than 1,200 gpm (630 MGY). Specified and installed high-
<br />capacity pumps and designed piping system for conveying well field water to 200,000 gallon storage tank.
<br />• Seminoe Road Pilot Project, Carbon County, Wyoming - Designed, installed, and tested a water treatment
<br />system for the removal of iron, manganese and barium at 3 surface water discharge points associated with 18
<br />coal bed methane (CBM) production wells.. Designed piping, valves, aeration tanks, filter tanks, and surface
<br />water NPDES outfall, including pressurized and gravity-fed segments. Provided recommendations for erosion
<br />control at outfalls and in-channel drainage structures.
<br />• Kinross Gold K-2 Mine, Washington - Designed a pumping and piping system to convey background mine
<br />water inflow from the 1290 level to a near-surface infiltration gallery. Evaluated water quality and potential
<br />water treatment requirements. Calculated friction losses and surge pressures, and specified pipe size and pump
<br />requirements for pressurized steel pipe system. Designed HDPE gravity piping system from the portal to the
<br />infiltration bed. Provided dimensions and specifications for infiltration bed components.
<br />• Kinross Gold K-2 Mine and Key Mill Site, Washington - Designed three gravity-fed infiltration systems for
<br />above-ground and in situ bioremediation of underdrain water and mine water via denitrification and sulfate
<br />reduction. Engineered the infiltration systems, prepared design report, and wrote O&M manual for infiltration
<br />bed components.
