Mr. Leavitt has been involved in the construction industry for over 15 years and has extensive experience with engineering, design, and calculation of surface water hydrology, fluid mechanics, and water resource problems. He has built, restored, remodeled, and stabilized many commercial and residential buildings. He has been responsible for reproducing and installing historically accurate windows, doors, logs and timbers, and other architectural millwork. He has designed and constructed alley ways, loading chutes, working corrals, and miles of fence. In recent years, Mr. Leavitt was also responsible for all construction tasks related to the placement of a five-mile long water pipeline and installation of an associated water tank supply system on a private ranch located in Big Horn Basin, Wyoming. All of the projects Mr. Leavitt has been involved with have been on time and under budget. Projects included the construction, rehabilitation and improvement of numerous buildings (hotels, cabins, campgrounds and dormitories) located on nine (9) separate properties within Yellowstone National Park. Responsibilities included peer review of plans and specifications, maintaining and remodeling of all buildings leased to the concessionaire, inspection of work performed, photo documentation, and preparation of detailed project reports for the National Park Service. Some of the buildings included Old Faithful Inn, Lake Hotel and Mammoth Hot Springs Hotel. He has been involved with many pipeline, erosion control, agricultural ditches, and responsible for all aspects of the rehabilitation of historic buildings and cabins including carpentry in the Bighorn Basin. Construction site de-watering in Cheyenne and Yellowstone National Park. Consulting on gas line easements, water storage, road development, placement of Coal Bed Methane (CBM) wells, plugging of water monitor wells, and research related to cost of re-injecting the excess CBM water in Campbell County Wyoming. Multiple storm sewer, sewer, water pipeline, removed and replaced fire hydrants, installed and maintained man holes and catch basins, and utility construction projects in El Paso County, Colorado.
Joe Alexis, P.E.
Project Mining/Metallurgical Engineer
Reclamation Services
Mr. Alexis has ten years experience in environmental remediation of mined lands and government installations that produced hazardous chemical materials and nuclear waste. Joe also has an additional twenty years of involvement in coal and mineral processing, including separation techniques and equipment related to froth flotation, magnetic separation, electro-static separation and gravity concentration. Mr. Alexis oversaw the construction and operation of coal and mineral pilot plants in the countries of South Africa, Canada, Madagascar and the U.S. Also in that time he designed, assisted in the construction and oversaw operations of a dredging and coal preparation facility for the recovery of fine coal from abandoned slurry ponds located in the Central U.S.
Reclamation/Construction
Reclamation Services
Mr. Kralic has over 15 years of “hands on” experience in the development, construction, operation, maintenance, and reclamation of mine sites. For the past 11 years, Mr. Kralic has focused primarily on small mine closures and disturbed land reclamation projects. His skills involve contractor management, production scheduling, compliance monitoring and documenting, and the coordination of field work projects. Mr. Kralic also has extensive experience and knowledge in metal fabrication, polyurethane mine closures, the operation and maintenance of process solution and stormwater control systems, streambed and streambank restoration, historic building restoration, and all types of monitoring and sampling (water, soil, and air). His experience and skill is highly regarded as an equipment operator in the reclamation and construction industries. Mr. Kralic is also trained and certified in First Aid, Hazmat, MSHA, and First Responder.

Senior Project Manager
Reclamation Services
Mr. Adams has designed, coordinated and managed environmental and mine reclamation projects over the past 15 years. With more than 25 years in mining, exploration, reclamation, and project management, Mr. Adams has extensive experience and practical knowledge in geology, permitting, environmental compliance, hydrology, budgeting, planning, construction management, and revegetation. As Site Manager, Mr. Adams was responsible for all reclamation and closure planning for the $12 million Basin Creek Mine Project. Responsibilities included conceptual engineering and hydrological designs, cost estimation, bid solicitation and contractual agreements, and construction oversight. Mr. Adams has experience in all phases of mining projects including exploration, sustainable development, production, reclamation and closure.
Dr. Donald H. Marx
Chief Scientist
Mycorrhizae and Soils
Dr. Marx is a world renown authority on mycorrhizal fungi and their practical
application. His is the 1991 recipient of the prestigious Marcus Wallenberg Prize awarded by the King of Sweden (considered the Nobel Prize in Forestry) for his international work on mycorrhizae for improved tree establishment on degraded land with the USDA Forest Service. For the past 40 years, Dr. Marx has pioneered the practical use of mycorrhizal fungi on native trees, forbs and grasses to solve problems in the reclamation/reforestation of mined land and other degraded sites. He has conducted field research in cooperation with several state AML programs, federal agencies and private mining companies to revegetate adverse sites, such as mined-lands, pollution-damaged sites like Copper Basin, Tennessee, borrow pits and other severely eroded sites. Dr. Marx's scientific and practical experience on the natural approach to reclamation programs is now available to PHC-REC clients.
Dr. Scott Kenner, Ph.D., P.E.
Senior Hydrologist/Engineer
Geomorphology/ Hydrology/ Mine Land Reclamation Design
Dr. Kenner has extensive experience in geomorphology and hydrology studies, sedimentation and erosion features and designs, surface mining and mine land reclamation design, and drainage and flood control designs. Regarding Surface Mining, Dr. Kenner designed a determination of hydraulic consequences of haul road, sedimentation ponds, and a diversion channel in Florence, CO. For the office of Surface Mining, he designed a manual for the control of surface runoff through sedimentation ponds in the Navajo Mine located in Farmington, NM. His experience also includes an analysis and preliminary design of erosion and scour protection for the Redlands Parkway Bridge, Grand Junction, Co. He's also done analysis in erosion protection, sedimentation, and hydraulics in Phoenix and Tucson, AZ. as well as in Alamo WA. Regrading Flood and Drainage control, he was in charge of flood insurance studies for the Arkansas River in Basin, CO. as well as completing a preliminary design and analysis of flood control and drainage improvements in Lafayette, CO. Dr. Kenner was responsible for designing a master plan for storm drainage in Upper Westerly Creek in Aurora, CO. Dr. Kenner is associated with numerous professional affiliations including the American Society of Engineers, the Water Environment Federation, the American Water Resources Association, the American Geophysical Union, and the National Society of Professional Engineers. He has been recognized for his numerous publications for the US Office of Surface Mining, the South Dakota Department of Environmental and Natural Resources, the Florida Department of Transportation, and the University of Florida, Gainesville. Dr. Kenner is incredibly qualified for any type of analysis and design for PHC-REC clients and is a prominent figure in our reports, reviews, and evaluations.
