Hi. I'm currently taking a course in land use and GIS systems. I'm brainstorming ideas for a final project that is 60% of my total grade. So far, I've narrowed it down to the presence of PPCPs (Pharmaceutical and Personal Care Products) that have been discarded domestically or are trated wastewater effluents in a certain water basin that supplies fresh water for the major part of the metropolitan area in Puerto Rico. I am trying to find a way to relate census statistics (mortality rates and population) to the incidence of a specific group of effluents (hormones, pesticides, analgesics) in a manner that may prove that their presence has indeed been a factor in the incidences of illneses and conditions such as cancer and cardiovascular disease. Any ideas or help related to ArcGIS or Q-GIS are definitely appreciated.
