摘要

The detection and quantification of two common fluorescent whitening agents (FWA) have been investigated in laboratory-prepared solutions, Lake Michigan water samples and secondary treated wastewater samples (from the Portage Indiana Water Reclamation Facility) using HPLC (High Performance Liquid Chromatography) equipped with fluorescence detection. Additional verification of the presence of FWAs is provided by high through put fluorescence spectrophotometry and excitation-emission matrix techniques. These water samples have also been analyzed for the presence of E coli using the membrane filtration method. The Lake Michigan water samples were collected from 3 different sites on the southern shore of the lake in Northwest Indiana: Burns Ditch and two nearby beach locations (Ogden Dunes Beach). Burns Ditch is the outfall of the Little Calumet River into southern Lake Michigan and directly impacts the Ogden Dunes Beach particularly during north to northeast winds.
