Speakers
Daniel S. Fisher, P.G.
Hydrogeologist with the Florida Geological Survey and Owner/Principal of Wetstone Solutions LLC.Mr. Fisher has more than 30 years of experience constructing hundreds of customized, site-specific, calibrated groundwater flow and contaminant transport models for both private and public clients. As a senior level hydrogeologist, he brings a comprehensive understanding of geology, hydrogeology, chemistry, mathematics, and physics to the table while using specialized investigative techniques such as graphical analyses, statistics, groundwater flow modeling and contaminant transport modeling. His experience includes all aspects of remedial and hydrogeological investigations including soil/groundwater sampling programs; groundwater monitoring system design; monitoring and extraction well installation and development; aquifer characterization, testing and evaluation; and many types of environmental data collection, management, and interpretation techniques in many geologic terranes. Mr. Fisher has experience with conceptual and actual designs for remediation of fuel and solvent-related soil and groundwater contamination at privately and publicly owned waste management sites. He knows the natural chemical characteristics of groundwater, as well as the occurrence and behavior of man-made organic and inorganic contaminants. Mr. Fisher’s experience allows him to conceptualize and describe complex problems and to present solutions in three-dimensions in order to bring clarity to complex technical discussions. He uses a wide variety of mathematical and modeling tools including: GMS, MODFLOW, MODPATH, MT3DMS, RT3D and PEST as well as simpler, less labor-intensive analytical models.
