John Moylan, the AEG distinguished lecturer, will be speaking on Stratigraphy at the CSUSB, AEG meeting on May 16 at the Castaways in San Bernardino. He will also be giving a guest lecture in the Stratigraphy class, on Wednesday, May 16 at 4:00 pm in PS-205. All geology students (and alumni and other interested parties) are invited and encouraged to attend that lecture, even if you are not in the stratigraphy class. His topic for the stratigraphy class will be “Strength Reduction in Shales – Causes, Effect on Stability, Case Histories, Recognition”.

If you wish to attend, you must RSVP to RSVP.

This month's meeting of the Inland Empire chapter of the Association of Environmental and Engineering Geologists will be on Wednesday, May 16 at the Castaways Restaurant at 679 Kendall Drive in San Bernardino. The speaker is John Moylan on “Site characterization for the design of effective groundwater remediation projects”. See abstract and biographical sketch below.

Abstract of Talk

Too often groundwater remediation projects have been implemented with too little site specific geologic, hydrogeologic, and geochemical site characterization data. There are differences of opinion as to whether groundwater can be effectively and efficiently remediated. In order to adequately address this question, we must openly and honestly discuss the factors affecting effective remediation, design and remediation methods, and perhaps most importantly performance monitoring data. Literature reports of remediation often provide very little information on the hydrogeology or geology of the site. These are extremely important types of data if groundwater remediation case studies are to be truly useful. Many articles never clearly describe the aquifer material, don’t state the range or distribution of hydraulic conductivities, or discuss the homogeneity or heterogeneity of the water bearing material. In these cases, it is seldom possible to determine whether the remedy being reported on is effective or efficient. Remedies are often selected on the basis of the Feasibility Study (FS) or Corrective Measures Study (CMS) data and the data available at the completion of the FS or CMS may not be sufficient to support effective remedial design or development of an effective performance monitoring plan. These data commonly don’t define many of the important subsurface parameters need ed to develop a good design. Developing and implementing a design without the benefit of sufficient design data commonly leads to an excessively costly remedy or one that does not remedy the problem. There are a number of geologic, hydrogeologic, and geochemical factors that potentially affect effective remedial design and rem ediation performance. In most cases, geologic, hydrogeologic, and geochemical factors are inter-dependant. Some of the important geologic, hydrogeologic, and geochemical factors are listed below.

Stratigraphic detail
Nature of porosity
Hydraulic conductivity
Confined or unconfined aquifer Boundaries
Pumping effects
Formation heterogeneity
Non-contaminant chemistry
Contaminant distribution
Is source present
Source nature and distribution

Projects in Kentucky and Colorado will be used to illustrate the importance of adequate site characterization for effective groundwater remediation.

Jahns Distinguished Lecturer


John E. Moylan has been named the 2007 Jahns Distinguished Lecturer. The Association of Environmental and Engineering Geologists and the Engineering Geology Division of the Geological Society of America (GSA) jointly established the Richard H. Jahns Distinguished Lectureship in 1988 to commemorate Jahns and to promote student awareness of engineering geology through a series of lectures offered at various locations around the country throughout the year.

Re: AEG Inland Empire Chapter Newsletter and Special Meeting Announcement

GSA/AEG 2007 Distiguished Lecturer in Engineering Geology
John Moylan, RG, Professional Geologist
"Site characterization for the design of
effective groundwater remediation projects"

Dear Members and Attenders.

Please attend this meeting as it is a privedge to have the opportunity to hear from a distinguished lecturer in Engineering Geology. As well, John Moylan will be providing lectures on other topics at the three public Univerities in the Inland Empire that week (University of California, Riverside; California State Polytechnic University, Pomona; and California State University, San Bernardino). Another special part of the this meeting will be the awards of financial assistance to undergraduates from each of those institutions of higher learning for supporting costs of undergraduate Geology Majors for field trips and Summer Field Geology camps.

Please note that advanced RSVP is required, no late RSVP, no admittance at the door without RSVP.

Also this month's Newsletter has abundant news. Please take note of the announcement for the soon-upcoming Geology Continuing Education Series course "Earthquakes and Seismic Hazards" Saturday May 12, 2007. Registration is ongoing with several enrolled already. - Rick AEG 7745 PG 5602 CPG 8518
