Current research in our laboratory is divided among assessing urban regions as sources of organic contaminants to coastal air- and watersheds in the Chesapeake Bay region, developing technologies to remove contaminants that harm the aquatic environment, and developing analytical methods. Existing projects are devoted to quantifying organic substances, primarily contaminants such as polycyclic aromatic hydrocarbons and polychlorinated biphenyls, in urban runoff entering the Potomac River (Washington, DC) watershed, and characterizing how engineered biofilters act to reduce contaminant loads to streams and rivers in urban regions. Urban runoff alters water and sediment chemistry and quality. Treatment technologies can minimize environmental impacts. The final principal area is the development of new analytical methods for the detection and quantification of emerging organic contaminants in the environment, which is currently focusing on the HPLC/MS and GC/MS determination of pharmaceutical compounds in wastewater discharges to coastal rivers.
