Maximize both the economic and technical considerations for the rehabilitation of water wells.
Economic conditions and land availability limitations have discouraged high-volume water well owners (including municipalities, water companies, industrial entities, and other large well owners) from incurring the cost of installing new wells. However, the requirement of water purveyors and other well owners to provide a safe and dependable supply of high-quality groundwater is unchanged. Recent drought conditions in some areas have increased the demand for groundwater supplies, and in less arid areas, groundwater wells are also needed to mitigate security concerns or treatment costs. This topic will help those responsible for groundwater systems to maximize both the economic and technical considerations for the rehabilitation of water wells. The material will include discussions of the maintenance (cleaning) aspects of well rehabilitation and the augmentation (structural modification to achieve improved water quality or greater production) aspects of well rehabilitation. Practical applications and case studies will be used to exemplify the usefulness and also the pitfalls of well rehabilitation.
