摘要: When wastewater infiltrates into the soil, groundwater may be contaminated. If distance from source of pollution to point abstraction is small, there a real chance abstracting pathogenic microorganisms. In this book, transport Escherichia coli in aquifers under saturated conditions studied. Starting well known colloid filtration theory. Straining or physical sieving, geochemical heterogeneity, variable deposition rate coefficients, and preferential flow mechanisms are then included The case Sanaa, capital Yemen, served evaluate importance bacteria processes field situation. This book useful for hydrogeologists concerned with microbiological contamination aquifers.
