Emmanuel Charles

I have been a hydrologist with the USGS New Jersey Water Science Center since 1993. My work relates primarily to groundwater systems, numerical modeling, estimating recharge, the use of artificial neural networks, and a variety of water-quality issues including those with detention basins.

Biography

I grew up and worked on the family farm until I changed course and earned a B.A. in geology from Franklin and Marshall College and an M.S. in geology from Miami University. Before USGS, I worked for several hydrogeologic consulting firms and spent six years with the New Jersey Geological Survey.

EDUCATION

M.S., Geology, 1989, Miami University, Oxford, Ohio

B.A., Geology, 1984, Franklin and Marshall College, Lancaster, Pennsylvania

WORK EXPERIENCE 

1993-present, USGS New Jersey Water Science Center, Hydrogeologist, Performed a wide range of project activities including: Developed four numerical ground-water models to assess groundwater flow regimes in southern New Jersey. Coordinated a variety of activities for a study of the occurrence, transport and fate of pollutants in the atmosphere, unsaturated zone, and unconfined-aquifer system in a coastal plain settting. Prepared detailed basin-scale assessments of unconfined aquifer systems: hydrogeologic framework, water-table maps, streamflow and base-flow statistics, groundwater and surface-water quality, and land-use, water-use and population trends.

1989-1993, New Jersey Geological Survey, Trenton, NJ, Principal Geologist, Developed a now widely-used empirical methodology to estimate groundwater recharge in New Jersey.

1987-1989, New Jersey Geological Survey, Trenton, NJ, Principal Geologist, Provided technical and regulatory support for groundwater pollution cases.

1987, STS Geotechnical Consultants, Lansing, Michigan, Part-time Assistant Geologist, Provided technical and consulting support for geotechnical and groundwater pollution cases.

1985-1986, Graduate assistant Miami University, Oxford, Ohio, Research Assistant and Teaching Assistant for undergraduate geology courses and a graduate geology course.

1981-1984, Carlyle Gray & Associates, Lancaster, Pennsylvania, Part-time Assistant Geologist, Office and field work for a variety of geological and environmental cases.
