"Practical Manual of Groundwater Microbiology" addresses the microbiological events that can occur in groundwaters. These include the phenomena of biofouling, corrosivity, biodegradation, and shifts in hydraulic transmissivity that can be linked to microbial events. The book emphasizes the form in which microbial events. The book emphasizes the form in which microbial events occur (e.g., biofilm formation), activities become focused (e.g., at the REDOX fringe), and production characteristics are affected (e.g., production capacity declines). Practical approaches to the evaluation of these effects are introduced, including standard and novel methodologies.
