The Wet/Dry Atmospheric Deposition monitoring program encompasses an area from the northern end of the Kissimmee River, south to the Everglades National Park. From 1974 to 1987 bulk rain collectors were used to collect rain water samples.
In 1987 the District switched to Aerochem Wet/Dry precipitation collectors, and in March of 1992, based on recommendations from the USGS, the District changed its protocol for the Wet/Dry precipitation collectors to that used by the National Atmospheric Deposition Program (NADP).
The rain program was established to provide a water quality data base for
1.Determining nutrient concentrations in wet and dry atmospheric deposition
2.Determining nutrient loading rates
3.Refine trend analysis and
4.Determining spatial variability.
5.Permit compliance for the ENR project.
