Application of heat and chemicals to a biofouling well is a relatively new approach for water well rehabilitation.
For the first time, The Application of Heat and Chemicals in the Control of Biofouling Events in Wells explains what many microbiologists now believe is the most effective form of treatment: pasteurization and application of chemicals.
Consider an increasingly prevalent alternative to traditional forms of encrustation: an approach which recognizes that water wells are conduits to the sub-surface realm, whose organisms impact the production characteristics of wells.

oExplains the process of blending chemical and heat treatments
Discusses the pasteurization of water wells
Provides case studies to illustrate the process
