This condition has been caused by a drop in water elevation in the well columns, possibly resulting from the current drought. A review of data from the St. Johns River Water Management District on Floridan Aquifer wells (see attached) shows this condition occurring at other wells in the state. Camp Dresser & McKee (CDM ) has recommended extending the pumps 20 feet deeper into the wells . CDM has performed the necessary engineering calculation and has certified that this recommended modification would not negatively effect the performance of the wells and pumps . Due to the critical nature of this situation, staff has instructed CDM to proceed with extending the pumps for wells 6 and 3 the recommended 20 feet. In addition, staff has instructed CDM to proceed with similar modifications on the other four wells ( 1 , 2 , 4 and 5 ) . These wells are at the same aquifer depth ( 700 feet ) as 6 and 3 . At staffs request, CDM has prepared an emergencv Work Authorization No . 18 ( see attached ) in the amount of 583 , 500 . 00 . This Work Authorization will provide the necessary materials and labor to extend all six wells the needed 20 feet .
