The water that flows from Blue Spring comes from rainfall in the 130 square mile springshed, which encompasses portions of five cities within Volusia County. The rainfall seeps down into the aquifer and slowly flows through the limestone
before discharging at the spring. It takes less than 43 years for most of the rainfall to make its way through the aquifer to the spring. Along the way, the water picks up pollutants that are ultimately discharged at the spring and that affect the ecological health of the spring run.
