Replacing a 200 foot deep well with a 2,500 foot deep well brings multiple challenges, especially in identifying underlying geologic structures, formation characteristics and aquifer properties. The initial target depth of the replacement well was 2,000 feet. However, due to the complex geology (folding), the depth was extended to 2,500 feet and penetration in the target aquifer was significantly reduced. The well was constructed, developed and tested with less than optimal results. Specialized industry techniques were utilized to enhance the yield in the aquifer. Equipping the well also created challenges due to a deep pump setting (1,900+ ft), specialized pumping equipment and apparatuses, elevated head pressures and a specialized startup procedure.
