Estrogens in treated wastewater that find their way into temporary wetlands known as vernal pools persist for weeks or even months, according to researchers, who suggest that persistence may have implications for these critical aquatic habitats.

Using a network of up to 60 citizen scientists, a team of Penn State researchers will assess the levels of endocrine-disrupting compounds in the Susquehanna River next year, and in turn empower those volunteers to become part of the solution to water-quality problems related to emerging contaminants.

With more than two dozen companies in Pennsylvania manufacturing potato chips, it is no wonder that researchers in Penn State's College of Agricultural Sciences have developed a novel approach to more efficiently convert potato waste into ethanol. This process may lead to reduced production costs for biofuel in the future and add extra value for chip makers.
