For the past several years, my research has been concentrated on the analysis of soil samples for environmental and trace evidence/forensic purposes, and on study of the elemental composition and crystalline structure of cremains and skeletal material, I have been honing my skills in x-ray analysis as well as learning some of the fundamentals of SEM-EDS. A large component of my research is geared specifically towards development of appropriate protocols and best-practice approaches for x-ray analysis of a range of materials and under a range of conditions. Techniques in non-destructive analysis are a key area of interest to me.
Non-aqueous phase liquids (NAPLs) are among the most common groundwater contaminants. Due to their low solubilities in water, NAPLs travel through the subsurface as separate liquid phases, resulting complex multi-phase clean-up problems. Their behavior in porous media and potential methods of remediation, have been the subject of active research for the past decade. However, the characterization of NAPL flow in fractured rock has lagged behind, and the potential effectiveness of remediation techniques remains unclear. The primary reason for this uncertainty is an insufficient understanding of the basic parameters controlling NAPL flow and distribution in natural fractures. While it is generally understood that flow and distribution of NAPL within single natural fractures are controlled by aperture distribution and connectivity, little experimental work has been done to characterize these attributes.
Using translucent polymer casts of single natural fractures it is possible to determine aperture and actively record flow using a digital camera. Because plastic polymers have significantly different wetting characteristics than natural rock, the surfaces of the replicates must be altered using a Radio Frequency Glow Discharge Plasma treatment.
