Micropollutants in the Potomac

Led by principal investigators Amy Fowler and Kim de Mutsert, the Summer Team Project looked at the effects of micropollutants on the Potomac River watershed. Projects were funded by the Students as Scholars at Mason as well as the Patriot Green Fund, and the videos were produced by graduate student, Chelsea Gray, thanks to the Virginia Sea Grant.

A New Way to Study Fish?

Written by: Jessie Melton

River herring, Alosa pseudoharengus and Alosa aestivalis, are an anadromous fish species that migrate from marine waters through estuaries to freshwater nurseries in order to spawn and lay eggs. River herring have historically been a valuable commercial species in fisheries, but the stocks collapsed throughout their native region along the Atlantic Coast since the 1990s. The Potomac Environmental Research and Educational Center (PEREC) has conducted an ongoing study of Gunston Cove for the past three and a half decades, and has incorporated the monitoring of river herring population to aid in determining whether or not the moratorium is beneficial to the decline in river herring abundance.

PEREC Faculty highlighted in Mason Spirit

Cindy Smith’s Human Dimensions and Biomes class (EVPP 302) was highlighted recently in Mason Spirit.

She found that some environmental science and biology majors were having difficulty finding jobs without a graduate degree. Looking for answers, she surveyed 10 employers and found that what they wanted most was were employees who had worked on “real” research projects and had “real” field experience. So she reworked the course to include an energy audit of a campus building, which is conducted in partnership with Mason’s Offices of Sustainability and Facilities….

“One of the best parts about my job is the interaction with the students during plant tours—and getting new ideas from them that we can possibly use to save energy,” says Jeffrey Counts, superintendent of the heating and cooling plant in Facilities Management.

Water: A Fish’s Pharmacy

Written by: Tabitha King

Here you can see Lisa McAnulty and I weighing out sediment to begin the extraction stage of sample processing. We are and will be using an adaptation of a QuEChERS (Quick, Easy, Cheap, Effective, Rugged, Safe) method to process both our sediment and fish tissue samples.

What if I told you fish could potentially be ingesting caffeine, pain medicine, and other pharmaceuticals on a daily basis? You may be wondering how this is possible since fish do not regularly visit the pharmacy to pick up their prescriptions. However, there is a growing concern amongst scientists and other stakeholders that the very medications we are taking (even common allergy relievers) are not being removed during wastewater treatment. Current regulations placed on wastewater treatment plants do not require the removal of such substances. To make matters worse, if a treatment plant was to take on the task of removing pharmaceuticals from their customers’ sewage, there are new compounds made on a daily basis. Each chemical would require a unique form of effective removal to ensure at least a majority is removed before treated water is discharged into local waterways. It is currently not known at what amounts of these medications are making their way into our local waterways and accumulating in aquatic organisms and sediment.
