The main objective of this work is to provide a procedure to identify fecal coliform bacterial contamination sources within specific regions employing Geographical Information Systems (GIS) technology. The work presented is one of the first efforts in the stage of problem identification from bacterial sources. A Total Maximum Daily Load (TMDL) is needed to be developed within the region of Rio Grande de Añasco, Guanajibo and Yagüez Watersheds. A TMDL is a quantitative representation of the maximum load of a given water-quality constituent, from all point and non-point sources, that any water body can assimilate without violating the designated water-quality standard established by EPA. The Guanajibo and Yagüez watersheds were selected for the demonstration of the application procedures developed under this research. The simulation helped to visualize the impacted zones by Fecal Coliform Bacterial sources, leading to better management practices and TMDL modeling.
