- 'The overall objective of this research is to investigate the influence of coupled physical and chemical heterogeneity on the migration and entrapment of DNAPLs in the saturated zone. This research includes laboratory and numerical investigations for a matrix of fluid and solid properties encompassing a range of wettability characteristics. Specific objectives include: (1) quantification of medium wettability and interfacial tensions; (2) determination of hydraulic property relations; (3) two-dimensional infiltration experiments; (4) modification of a continuum based multiphase flow simulator to account for physical heterogeneity, saturation independent and saturation dependent wettability, and concentration dependent wettability and interfacial tension; and (5) utilization of this model to explore the potential influence of coupled physical and chemical heterogeneities on the migration of DNAPLs and the development of innovative remediation schemes. Research conducted during this period was directed primarily towards the accomplishment of goals (1), (2), (4) and (5); specific details are given below. Goal (3) builds upon results from the other objectives and will, therefore, be started in the coming year.'
