Salt-water encroachment is undoubtedly the problem of most concern to
users of ground water in Florida. This is a problem in many coastal areas
where water levels are lowered excessively by heavy pumping. It is a
problem also in some inland areas where the water-bearing formations contain
salty water at relatively shallow depths. Among the coastal areas where wells
have become contaminated with salt water are Pinellas County and the Miami
area of Dade County. Inland areas where wells are likely to become contaminated
with salt water include Seminole County and the southwestern part
of Volusia County.
The purpose of the investigation is to make a detailed study of the
geology and ground-water resources of the county with special emphasis on
the problems associated with declining water levels and salt-water
contamination. This report reviews briefly the progress of the investigation
through February 1954. (PDF contains 43 pages.
