Phosphorus is an essential element for life and is often a limiting
nutrient for crops. For this reason, itsmajor use is as fertilizer for
agriculture and farm production.
All the data was downloaded from the Florida Geographic Data Library
website: http://www.fgdl.org/metadataexplorer/explorer.jsp. Thedata
was added in the software ArcGIS – ArcMap 10.
Properties within the PRB:
• It is estimated that about 1 million people have their water supply
from wells within the PRB;Phosphorus excess in water bodies can contribute to excess
growth of algae, a condition known as eutrophication.
PWS wells within the PRB:
However, the wells used to supply the populationwith water can
be passive of contamination.
The objective of this project is to identify properties with
agricultural use that are located within the Phosphorus Restricted
Basins (PRB), and theneducate and alert their owners about a
controlled phosphorus use.
The properties and the Public Water System (PWS) Wells within the
PRB were identified:
• The addition of largequantities of phosphates to waterways
accelerates algae and plant growth in natural waters .
• Population supplied by the specific wells and volume of water:
The 4 watersheds are Lake Okeechobee,Lake Apopka, the Green
Swamp and the Everglades Protection Area (EPA), and the
counties include all of Glades, Hendry and Okeechobee
• Because phosphorus can be applied in agriculturalactivities,
such farmers must be made aware and educated to use the right
amount of fertilizers, to avoid runoffs and leaching of phosphorus
to the watersheds and groundwater;
