Project Summary: This study proposal seeks to address the problem of source water contamination with hazardous organic micropollutants (OMPs) generated by agricultural runoff and wastewater effluent discharge in the United States and particularly the North Dakota region. The presence of OMPs in water can endanger human health and aquatic life, and yet the available water treatment technologies for these contaminants are either inefficient, expensive or produce additional harmful by-products from the treatment process. Recently, KrCl* Ultraviolet light excilamps emitting at 222 nm have emerged as a new technology that has demonstrated promising results in the removal of OMPs by direct photolysis and advanced oxidation processes. The main purpose of this research is to explore the efficacy of KrCl* excilamps in removing OMPs from agricultural runoff and wastewater effluent, and in doing so will help offer a fundamental understanding of this technology's potential for the treatment of contaminated water.
