Previous Water Sources:
Prior to 1998, Pinellas County’s drinking water production started with safe and reliable water located deep beneath the ground. In Pinellas County, groundwater comes from the Floridan Aquifer, a thick sequence of porous limestone beneath the Earth’s surface which spreads throughout Florida as well as parts of Alabama, Georgia and South Carolina. This water-rich source is considered to be one of the largest freshwater aquifers in the nation, and can provide the safest and highest quality water available.
