emerging contaminants

This issue hit the front page of the Washington Post September 6, 2006 with the announcement that the majority of male bass in the Potomac River were producing eggs, known as intersex fish. Scientists at the U.S. Geological Survey (USGS) broke this story with new research out of their Fish Health Branch at the Leestown Center in West Virginia . State and federal agencies, universities and NGO's have assisted in building a body of evidence that points to a class of compounds called "emerging contaminants" are to blame. Our former Shenandoah Riverkeeper Jeff Kelble and current Shenandoah Riverkeeper Mark Frondorf provide direct assistance to the USGS scientists as they continue their research. In the past, Jeff Kelble provided leadership and expertise on Virginia's Fish Kill Task Force.

These contaminants are loosely defined as man-made chemicals which are designed to mimic hormones, or which accidentally mimic hormones, even in extremely low concentrations, and which confuse animal’s growth and reproductive systems. These chemicals and compounds range from pesticides to herbicides, medicines, metals, and personal care products. Three things trouble us the most about these compounds:

  • They can be more potent in low quantities than high quantities.
  • Our drinking water treatment systems are currently incapable of filtering most of them out of our water source.
  • They are generally not well understood and are definitely not regulated as a rule.

Position: Our position is that contaminants that cause deformities and intersex in animals have no place in our drinking water sources, rivers and environment. Yet there are very few clear targets for advocacy. Clearly, those causing acute impacts need to be regulated. And regulating emerging contaminants will take federal government leadership, which has been, and continues to be, lacking. Even with funding EPA has failed to produce a single standard under which regulate.

Objectives: In the absence of a clear advocacy goal we continue to work with scientists to develop funding for studying these contaminants, participate and support the studies, and look for an NGO role in advancing protections around these compounds.

USGS Shenandoah Smallmouth Bass Research Beginning to Find Answers

Shenandoah Riverkeeper began working with Dr. Vicki Blazer, of the USGS National Fish Health Research Laboratory in Kearneysville, WV, during the 2005 Fish Kill Task Force. Since then, we’ve assisted in the lab’s collection efforts and have been the eyes and ears for happenings on the river. The result of this collaboration is a greater […]

What’s Behind the Fish Kills on the Shenandoah?

Now that the summer has officially arrived, everyone wants to know how the fishing is doing on the Shenandoah River. Unfortunately, for this season, I am afraid it will be a bit of a slog, but there are a couple of encouraging signs that bode well for the fishery in future seasons. In 2014, a […]

Earth Day Special Blog: Threats to the South Branch of the Potomac River

By Brent Walls, Upper Potomac Riverkeeper We are all connected to the river in some way or another. Many of us have childhood experiences of splashing in a cool stream from a rope swing, floating down the river in a black inner tube, or casting a line with a family member. Some of us continue […]
