Electromagnetic Survey of the Headwaters of North Branch of Potomac River, Important Tributaries, and Impacting Mines

 

Paul Petzrick, Maryland Power Plant Research Program, Annapolis, Maryland

 

In 1999, the National Energy Technology Laboratory (NETL) acquired a Helicopter Electromagnetic Survey (HEM) of the Kempton/Coketon Mine Complex for the Maryland Power Plant Research Program (PPRP).  NETL’s interest was in studying remote sensing as a means of identifying water quality problems from mining, and PPRP’s interest was in planning geoengineering projects to permanently restore water quality in streams degraded by abandoned pre-law mines.  The 1999 HEM revealed important benefits and limitations of this type of survey that might now be performed by drones.  The data from the 1999 survey is particularly important when coupled with other data collected for PPRP by Garrett College and the Western Maryland Regional GIS Center in understanding the massive two-State, 64 square kilometer, surface and underground mine complex that disturbs the headwaters of the Potomac River.

 

Mr. Petzrick’s presentation will discuss interpretation of the HEM data, the importance of software for conversion of the data to useful graphics for planning restoration projects, and alternate methods of remote sensing and their conversion to useful graphics.  The data and its interpretation in each case has been the subject of significant review by NETL and its support contractor and similarly by experts at PPRP’s support contractor, Environmental Resources Management, Inc.  The importance of historical information and utilization of water quality data as a tool in assessing environmental issues will also be addressed.

 

Biography

 

Paul Petzrick is a Senior Engineer and Scientist at the Maryland Power Plant Research Program (PPRP) with a focus on Civil and Environmental Engineering.  He has been with this Program in the Maryland Department of Natural Resources for 23 years after finishing 30 years of Federal service that included 20 years as a Navy Civil Engineer Corps officer and 7 years of Senior Executive Service at the U.S. Department of Energy.  He had applied mathematics education at the University of Wisconsin and has Engineering Degrees from the U.S. Naval Academy, RPI, and Princeton (M.S. 1966).  At PPRP he is primarily responsible for the beneficial use of by-products (ash and CO2) of producing electricity.
