<br />Susan A. Wyman, P.E., P.G. <br />• Schwartzwalder Aline. 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 />• SchwarL-walder 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 />• Schwartwalder Mine, Colorado - Collected stream samples to investigate water quality above and below <br />Schwartz Trend Crossing on Ralston Creek. <br />• Schwartzwalder Aline, 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 />• Io'an 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 3'd party EIS contractor to the US Bureau of Land Management. <br />. North Rasmussen Ridge :Aline. 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 party 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 Malley 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 Aline and Key Alill 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. <br />9150.100630 Page 2 of 6
