Welcome to Dr. Harriette L. Phelps Website

As a professor in the Biological and Environmental Sciences Department of the University of the District of Columbia my research interests have been primarily in the field of water pollution biomonitoring using molluscs and ecological aspects of bivalve populations. 

Working with students I studied metal accumulation in oysters (Crassostrea virginica) related to power plant operation and metal contamination in the Chesapeake Bay.  I developed biomonitoring of sediment pollutants using clam burrowing  behavior and also using survival of pediveliger oyster larvae (Crassostrea gigas) and juvenile Asiatic clams (Corbicula fluminea). 

In Portugal I studied tributyltin water pollution using the oyster shell thickening index with the Portuguese Oyster (Crassostrea angulata).  Students and I have examined the ecological effects of the invasive Asiatic clam population (Corbicula fluminea) in the freshwater Potomac River estuary near Washington, DC. 

On sabbatical I studied life cycle aspects of the Australian freshwater clam (Corbicula australis).  With support from the Water Resources Research Institute of the District of Columbia I am using active biomonitoring with the Asiatic clam, (Corbicula fluminea), to identify point and nonpoint sources of EPA Priority Pollutants in the freshwater Anacostia River watershed of Washington DC and Maryland.  My other research has examined remote sensing identification of freshwater pond algal populations.
