Pinellas County, which includes St. Petersberg and Clearwater Florida, is a large barrier island in the Gulf of Mexico, forming the west side of Tampa Bay. Like many communities situated along the sandy coastline, its water supplies depend upon floating its supply of fresh water in sandy groundwater. Withdraw too much fresh water, and salt water from the sea penetrates from the side and below.
What is the solution? Return treated wastewater effluent to the ground and keep the fresh afloat on top. How can this be done? Make gold course irrigation mandatory with re-claim water.
