Water-supply problems in southwest Florida are largely related to the quality, or deterioration in the quality of the water, rather than to the quantity of water available. When we consider that the abundant supply of water visible at the surface is only a fraction of the quantity stored in the ground-water reservoir beneath the surface, we are likely to conclude that the quantity of...

The presently available data on streamflow, runoff rainfall, and temperature of Puerto Rico are evaluated, although the period of record is very short, with a view to contributing to the knowledge of hydrology of tropical islands. The average annual streamflow in Puerto Rico is 45 percent of the annual rainfall, or 15 percent more than in the eastern piedmont of the U.S. where it is 30...

During the Chilean earthquake of May 22, 1960, intensity 8.5, 4 of 8 wells in Puerto Rico equipped with automatic recorders, recorded seismic fluctuations. The maximum double amplitude, 0.05 ft, was recorded at a well in bedrock near Coamo. Double amplitudes in 3 other wells ranged from slightly less than .01 to .02 ft. Following the Puerto Rico earthquake of Aug. 2, 1961, intensity...

Introduction During 1950, a series of 43 test wells 30 feet deep were drilled by the United States Corps of Engineers along the western edge of the Everglades from the Tamiami Canal northward to the Caloosahatchee River. The cores obtained from the wells afford geologic data along a line from the lower Everglades of Dade County, where both the geology and water resources have been...
