To improve accuracy, the Southwest Florida Water Management District (District) has upgraded the datum used to record water level elevation.  The District has upgraded the datum, or starting point, used to record water level elevation at its data collection sites. Water elevation is measured in feet above mean sea level. The datum was upgraded from the National Geodetic Vertical Datum of 1929 (NGVD 29) to the North American Vertical Datum of 1988 (NAVD 88… Read more

Aquifers are underground layers of rock and sand that hold water. These layers are made up of loosely packed sediments and layers of calcium-rich limestone and dolomite. In Florida, most of the population depends on the Floridan aquifer for their drinking water. The Floridan aquifer, which is the largest and deepest aquifer in the state, holds groundwater like a sponge. Holes in the rock that make up the aquifer allow the water to move freely through it. Aquifers are… Read more

Both the United States government and Florida have adopted water quality goals and standards. Each water body has its own standards. For example, water used for drinking has to be much cleaner than water used for crop irrigation or to cool machinery in a factory. Scientists use information from water monitoring to determine how a water body rates based on its intended use. If scientists rate water quality as GOOD, then the water can fully support its… Read more
