urging and Sampling Device Selection Criteria; Operational Characteristics, Applications and Limitations of Grab Samplers, Suction-Lift Pumps & Electric Centrifugal Submersible Pumps

Description

There are a lot more useful and appropriate purging and sampling device options available than the bailer!  Learn what types of sampling devices are appropriate for a variety of analytical parameters, and which devices should never be used for some parameters. This series of 2 modules (GWM-20 and GWM-21) provides a detailed discussion of a wide range of devices available for purging and sampling ground-water monitoring wells, including their principles of operation, operational characteristics, materials of construction, and limitations.  The discussion will provide a framework for evaluating any device to determine its suitability and appropriateness for site-specific and individual well-specific applications.  Field videos are included within each module to explain the operation and use of a variety of sampling devices.  While you may opt to take just one of these modules, it is strongly recommended that you take both modules in the prescribed order if you want comprehensive coverage of the subject.

  • Purging and Sampling Device Selection Criteria
  • Discussion of ASTM Standard D 6634 on Selection of Purging and Sampling Devices for Ground-Water Monitoring Wells
  • Impacts of Sampling Devices on Sample Chemistry
  • Overview of Available Sampling Devices -  Operational Characteristics and Limitations
    • Types of Devices Available
      • Grab Samplers
      • Peristaltic and Suction-Lift Pumps
      • Electric Centrifugal Submersible Pumps

David Nielsen

gwm2David M. Nielsen is President of Nielsen Ground-Water Science, Inc., the parent company of The Nielsen Environmental E-School and The Nielsen Environmental Field School.  He is a Certified Professional Geologist (AIPG #5040), a Professional Hydrogeologist (AIH #991), a Certified Ground-Water Professional (AGWSE #179) and a Certified/Licensed/Registered Professional Geologist in 7 states (AK, AR, DE, FL, IN, SC, TX). He has 40 years of experience in ground-water and environmental consulting, training and research. He has managed ground-water contamination investigations, environmental site assessments, ground-water monitoring and sampling programs, petroleum hydrocarbon spill investigations and remedial projects across the U.S.  David was one of the primary instructors for Princeton Groundwater's Groundwater Pollution and Hydrology Course for 12 years, and he has also developed curriculum for and instructed: undergraduate, graduate and continuing education courses in ground-water science at Wright State University; Technology Transfer workshops on Environmental Site Characterization and Ground-Water Monitoring and Sampling for the U.S. EPA; Waste Management, Inc.'s Landfill University; and a one-year Hydrogeologic Training Program for the Environmental Response Division of the Michigan Department of Environmental Quality. He has instructed more than 500 ground water and environmental science short courses and workshops for consulting firms, regulatory agencies, industrial concerns, the Department of Defense, the U.S. EPA, trade and professional organizations, educational institutes and universities in the U.S., England, Canada, Australia, Guatemala and Mexico. 

David is former Chairman of ASTM Subcommittee D-18.21 on Ground-Water and Vadose Zone Investigations, a consultant to the U.S. EPA Science Advisory Board, a member of the U.S. Department of Defense SERDP/ESTCP Peer Review Panel, and an advisor to the U.S. Department of Energy National Advanced Drilling and Excavation Technology Program. He is the editor and a contributing author for The Practical Handbook of Environmental Site Characterization and Ground-Water Monitoring (First and Second Editions; 1991 and 2006), The Essential Handbook of Ground-Water Sampling (2007) and Technical Guidance on Low-Flow Purging and Sampling and Minimum-Purge Sampling (2002). He is also a member of AIPG, the Association of Ground Water Scientists and Engineers, the American Institute of Hydrology and the Association of Engineering Geologists. He served for 12 years as Editor of Ground-Water Monitoring and Remediation and served for 12 years on the Wright State University Geology Department's Board of Counselors. He holds B.A. and M.S. degrees in geology from Miami University (1974) and Bowling Green State University (1977) respectively. Prior to co-founding The Nielsen Environmental Field School and Nielsen Ground-Water Science, Inc., he managed regional offices for two geoscientific and engineering consulting firms, served as Director of Research and Education for the National Ground Water Association and worked for state environmental agencies in Massachusetts, West Virginia and Ohio.

David has also written guidance documents on direct-push technology and ground-water sampling for the U.S. EPA Superfund program, and reviewed dozens of technical reports for the U.S. EPA's Environmental Technology Verification (ETV) program. He is the recipient of the Outstanding Service Award of the Association of Ground Water Scientists and Engineers, The Outstanding Achievement Award of ASTM, and a 4-time recipient of ASTM's Special Service Award.
