Estimating Floodplain Populations and Assessing Flood Risk and Flood Mitigation in Puerto Rico
This project performed floodplain population estimates and created population density maps for the municipalities of Bayamon, Catano, and Guaynabo. Our methods included the use of ArcGIS software to display aerial photographs, Census block data and FIRM data in the form of maps. A short survey was conducted to understand residents' flood experiences and awareness, as well as their trust in a catastrophe modeling system and flood alerts. The survey data were analyzed using SPSS, allowing us to make correlations between flooding experiences and preparedness among floodplain communities. These data will be used by the Planning Board to make population estimates for the rest of Puerto Rico and to better allocate resources for flood mitigation and prevention

Removal of Ciprofloxacin from Water with Chemical Oxidation
Contamination of water sources with compounds of emerging concern, such as ciprofloxacin (CIP), is becoming a large problem. Current water treatment facilities are not designed to remove pharmaceuticals. The objective of this project was to study the degradation of CIP from water through reactions with oxidative treatments. Reactants included hypochlorite, potassium permanganate, potassium ferrate, persulfate and Fenton’s reaction. The concentration of CIP after treatment was quantified using a UV spectrophotometer. Potassium ferrate, Fenton’s reaction and hypochlorite achieved over 90% removal. Persulfate and potassium permanganate did not achieve complete removal with the dosages administered. All treatment methods achieved greater extents of removal with greater dosages of oxidant
