Professor Masten’s research involves the use of chemical oxidants for the
remediation of soils, water, and leachates contaminated with hazardous organic
chemicals. Her research is presently focused on the in-situ use of gaseous
ozone to oxidize residual contaminants in saturated soils using ozone sparging
and in unsaturated soils using soil venting. Dr. Masten is also very interested
in evaluating the toxicity of the by-products of chemical oxidation processes
as measured by gap junction intercellular communication (GJIC). Work has
focused on the ozonation and chlorination of several pesticides, including
atrazine, alachlor, and lindane and on the PAHs, especially pyrene. Current
work is being conducted to identify the by-products formed upon the ozonation
of several PAHs and to assess their toxicity.
Professor Masten is also involved
in a project to use ozone in combination with fixed film biological treatment
for the control of disinfection-byproducts formed from the ozonation of waters
containing humic substances. Current work is focused on assessing changes in
the concentration and nature of complex organic matter during ozonation and
biological treatment. Advanced oxidation processes involving ozonation for the
oxidation of the polychlorinated benzenes has been investigated by students in
her research group. Work has focused on optimizing these systems for the
generation of OH radicals and the development of predictive models. She is also
working in the area of the control of odors from livestock wastes and in the
inactivation of Cryptos poridium parvum in drinking waters. Professor Masten is
also an Associate Member of the Center for Microbial Ecology.
