Description/Abstract The source of water to Lithia Springs adjacent to the Alafia River in Hillsborough County, Florida has traditionally been hypothesized to be from the Upper Floridan aquifer.^As a result, potential impacts from an adjacent public supply well field has been of interest since the well field began production in July, 1988.^The discharge from Lithia Springs since March, 1984 has averaged about 3,600,000 cubic feet per day.^Pumpage from the adjacent well field since July, 1988 has averaged about 2,500,000 cubic feet per day.^A comparison between mean daily pumpage from the well field and mean daily discharge from the springs showed no apparent association indicating that the Floridan aquifer may not be the source for the springs.^Lithologic data suggested that the Upper Floridan aquifer was confined with no direct connection to the springs.^This confining unit hypothesis was tested and accepted by pumping two wells close to the springs.^The test consisted of pumping both wells for about 13 days at a combined rate that was about 40% of the average daily well field pumpage.^No discernable test caused effects were observed on the springs or in an adjacent 115-foot deep well open to carbonate rock.^Because of this, it was concluded that the Upper Floridan aquifer was not the source of water to Lithia Springs.^Interpretation of available data suggested that the source of water to Lithia Springs was from the intermediate aquifer system located within solution riddled Early Miocene carbonate rocks of the lower Hawthorn Formation with maybe an important aquifer contribution from the Alafia River.
