Taylor & Francis Foppen, J: Transport of Escherichia coli in Saturated Porous

Examines hyper-exponential deposition of E. coli as a fecal contamination indicator through colloid filtration theory, straining mechanisms, geochemical heterogeneity, and preferential flow processes, using column experiments with glass beads and field evaluation in Yemen to demonstrate that E. coli attachment decreases hyper-exponentially with transport distance.
