Continuing Education Information

This webinar is open to the public and is designed to qualify for 6.0 PDHs for professional engineers in most states; please refer to specific state rules to determine eligibility.

HalfMoon Education is an approved continuing education sponsor for engineers in Florida (Provider License No: CEA362), Indiana (License No. CE21700059), Maryland, and New Jersey (Approval No. 24GP00049300). HalfMoon Education is deemed an approved continuing education sponsor for New York engineers and geologists via its course approval with the Practicing Institute of Engineering (PIE).

*This webinar has been evaluated for compliance with NYS Mandatory Continuing Education requirements for professional engineers and geologists by the Practicing Institute of Engineering, and has been approved for 6.0 PDHs. HalfMoon Education has not applied for state geologist continuing education approval in other states requiring such.

The Association of State Floodplain Managers has approved this course for 6.0 CECs for floodplain managers.

Attendance will be monitored, and attendance certificates will be available after the webinar for those who attend the entire course and score a minimum 80% on the quiz that follows the course (multiple attempts allowed).

*On-Demand Credits*

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.
