Charles Schalk

Charles started his career in 1990 in the Ohio WSC, where he worked on hydrogeologic flow modeling, database management, and wetlands identification. After moving to Maine in 2003, he worked on flood-insurance studies, algal bloom issues, and road-salt investigations. Charles is a member of the Ground-Water Users Group.

Education  M.S. degree, The Ohio State University, Department of Agricultural Engineering, 1990 B.S. degree, The Ohio State University, Department of Agricultural Engineering, 1988, cum laude with distinction  Selected Work History 2003-present - Hydrologist, U.S. Geological Survey, Augusta, Maine 1990-2003 - Hydrologist, U.S. Geological Survey, Columbus, Ohio 1988-1990 - Graduate fellow, Ohio Agricultural Research and Development Center and The Ohio State University 1984-1988 - Student employee, The Ohio State University Selected Work Experience:         2003-current (U.S. Geological Survey, Maine):  Committee member and chairman of the Ground-Water Users Group, a national committee that oversees the development of, testing of, documentation of, and training for the Ground-Water Site Inventory, a USGS national ground-water database. Worked closely with the Office of Ground Water to present ground-water related tools and developments to general audiences at conferences Investigated primary production of algae in a river system in northern Maine, in cooperation with the Houlton Band of Maliseet Indians. Used a USGS model (WSMP) to derived estimates of primary production and related them to natural and anthropogenic factors. Provided geographical information systems (GIS) support for many projects Participated in and managed scoping efforts for flood studies in Maine. Worked closely with State agencies to compile flood-related information and prepare and hold meetings with local managers and officers 2001-2003 (U.S. Geological Survey, Ohio) Committee member and chairman of the Ground-Water Users Group, a national committee that oversees the development of, testing of, documentation of, and training for the Ground-Water Site Inventory, a USGS national ground-water database Technical liaison with U.S. Environmental Protection Agency, Region V; U.S. Air Force Aeronautical Systems Center, Wright-Patterson Air Force Base; and contractors doing hydrogeological and contamination studies in the Evendale, Lockland, and Reading area of southwestern Ohio Proposed and managed several projects, including particle tracking at a municipal well field, nonjurisdictional delineation of wetlands, statewide estimates of ground-water vulnerability, development of digital GIS databases, and sampling for animal antibiotics in the environment Helped construct a ground-water-flow model using GMS for a phytoremediation project in Ft. Worth, TX Spoke at several conferences regarding USGS-Air Force programs and flow-modeling work Participated in technical conferences about phytoremediation, database management, and animal pharmaceuticals in the environment 1990-1995 (U.S. Geological Survey, Ohio) Constructed two separate three-dimensional, steady-state and transient ground-water-flow models using MODFLOW and a GIS interface (ARC/INFO) Sampled ground and surface water in a haz-waste Level D environment Measured saturated hydraulic conductivity by the slug method Lectured on ground-water-flow modeling and GIS applications to Air Force personnel Populated and managed a large relational database for an extensive water-quality project. Included data entry, handling, loading, and quality-assuring; developed applications (in C) for reporting purposes Managed an Air Force project, overseeing the writing of the report at the end of the project Measured in-situ unsaturated hydraulic conductivity by three methods Installed metering equipment for flow and water-quality monitoring at a drainage research site Thesis: Modifying the hydrology component of the ADAPT model (FORTRAN programming and code development to simulate hydrologic processes and response in the unsaturated zone)
