Chemicals Used in Water Well Rehabilitation -- Part 1
Chemicals are used in water well rehabilitation to remove products that are either contaminating the well water or blocking or plugging the well environment.
Contamination can be the result of chemical infiltration into the well, such as the leakage of turbine oil into the well environment or the appearance of coliform bacteria from some contaminating source. Well blockage or slowdown can be caused by the mineral buildup on screens or in flow spaces of the gravel pack or formation, and/or the biological buildup on these same surfaces.
