"I first got involved with research my freshman year after hearing about the rewarding experiences my mentors had with it. Once I started in the lab I fell in love with doing research when I realized the endless possibilities for discovery and creativity. Now I continue to do research to help protect and preserve our water resources, and ensure water quality."

Research Description

Evaluating the Effects of Salt Water Intrusion on the Natural Organic Matter Removal Efficiencies of Lime Softening, Anion Exchange and Coagulation Processes for Drinking Water Treatment
The main goal of my research project is to determine how the presence of salt water intrusion affects the efficiency of typical drinking water treatment processes, such as coagulation, lime softening and anion exchange. It is important to understand how salt water intrusion is affecting the removal of organic matter (NOM) so that drinking water treatment plants can make informed decisions before, during, and after salt water intrusion events to protect and preserve drinking water quality and apply suitable pretreatment methods for reverse osmosis. In the lab I simulate salt water intrusion events on source waters from coastal drinking water treatment plants around Florida. These waters then undergo coagulation, lime softening, and anion exchange to remove the NOM. UV254 measurements are then taken and analyzed to compare which treatment process is able to remove the most NOM in the presence of salt water intrusion. This research will help plant operators better handle salt water intrusion events, protect water quality and effectively pretreat source water for treatment by reverse osmosis.
