NGWA Announces Four Upcoming Events

Webinars and courses offered throughout October

The National Ground Water Assn. (NGWA) is offering four upcoming events.

The fourth in the "Tuesdays with Ian" webinar series, "A Practitioner’s Guide to Isotope Hydrology," will be held on Oct. 19 at 11 a.m. EST. The webinar will be presented by Ian Clark, Ph.D., professor of isotope hydrology, University of Ottawa, Canada, and will be presented at a level appropriate for all groundwater professionals including environmental consultants, consulting engineers and geologists, and water supply engineers.

The three-day course, “Environmental Geochemistry of Metals: Investigation and Remediation,” will be held Oct. 18 to 20 in Albuquerque, N.M. The course provides practical information needed to effectively evaluate intrinsic remediation and chemical manipulation of sites contaminated with metals, nonmetals and radionuclides. Chemicals of concern to be discussed include aluminum, antimony, arsenic, barium, beryllium, boron, cadmium, chromium, cobalt, copper, iron, lead, manganese, mercury, molybdenum, nickel, nitrogen, perchlorate, selenium, silver, thallium, uranium, vanadium and zinc. Intrinsic remediation of several radionuclides will also be covered. Attendees should possess a basic understanding of groundwater geochemistry, hydrology and mineralogy. Two semesters of undergraduate chemistry and a degree in Earth sciences or civil/environmental engineering are recommended. The course instructors are Bill Deutsch, senior geochemist at Pacific Northwest National Laboratory operated by Battelle, and Patrick Longmire, Ph.D., hydrogeochemist at Los Alamos National Laboratory.

The NGWA is also offering a new course, "Site Characterization: The Groundwater System," on Oct. 21 in Albuquerque, N.M. This course covers data needs and sources, as well as presentation tools for characterizing both the geologic framework and groundwater system. It also addresses synthesizing their relationship, especially recognizing important geologic controls of groundwater occurrence, movement and quality. Participants will receive the book Hydrogeology in Practice: A Guide to Characterizing Ground-Water Systems, which serves as the reference for the course.

A webinar titled, "Geological Storage as a Carbon Mitigation Option” will be held Oct. 26 at 2 p.m. EST.The webinar will be presented by Michael Celia, Ph.D., professor of Civil Engineering, Princeton University, and 2008 National Ground Water Research and Educational Foundation Darcy Lecturer.

Anthropogenic emissions of carbon dioxide have increased atmospheric concentration of CO2 by about 35% over the past 200 years. If this increase of atmospheric CO2 is to be reduced, or reversed, technological solutions must be implemented on a massive scale.

While many options are being considered, one attractive approach is carbon capture and storage, or CCS. The "geological storage" version of CCS involves capture of CO2 before it is emitted into the atmosphere, and subsequent injection of the CO2 into deep geological formations. A series of simplifying assumptions may be proposed to provide more efficient numerical calculations, even to the point of allowing for analytical or semianalytical solutions. Such simplifications, which fit naturally into a multiscale computational framework, allow for large-scale analysis of leakage in a probabilistic framework while capturing much of the essential physics of the problem.

Through example calculations about the utility of these methods, participants will learn how general multiscale approaches can provide solutions for important practical problems. The Webinar will be presented at an intermediate level for groundwater professionals including environmental consultants, consulting engineers and geologists, and water supply engineers.
