Octanol-water partition coefficients (Kow) vs. pH for fluorescent dye tracers (fluorescein, eosin Y), and implications for hydrologic tracer tests
fluorescein eosin Y tracer octanol-water retardation
2017/4/11
Values of the octanol-water partition coefficient (Kow) have been measured vs. pH for two fluorescent dyes (fluorescein,
eosin Y) commonly used in hydrologic tracer tests. Values for both fluorescent...
Solute transport in fractured media–analysis of non-reversibility in tracer tests
Solute transport fractured media non-reversibility tracer tests
2009/11/2
This paper describes several small-scale (laboratory) experiments designed to simulate solute transport through fractured formations. A block of granite was broken to produce a fracture similar to tho...

A methodology based on a combination of numerical simulation of conservative
transport and an analytical solution for combined matrix diffusion and surface
sorption is presented for the study of tra...
Effects of Well Arrangement on Characterization of Discrete Fracture Systems by Inverse Analysis of Tracer Tests
Tracer test Fracture system Inverse analysis Boundary element method
