habitats.

Scott’s most recently approved project—Villages of Piedmont at Leopold’s Preserve (VOPLP)—which broke ground in late October 2013, has been touted by Prince William County officials as a model for preservation-oriented land planning. VOPLP, which is located in Haymarket, VA, will complete the balance of an existing community with the addition of 393 new homes in a unique cluster design. One of the most compelling aspects of the project is the impressive open-space commitment—the permanent conservation of more than 380 acres—known as Leopold’s Preserve. Named after famous conservationist, Aldo Leopold, Leopold’s Preserve will be preserved through a conservation easement as natural open space and open to the public for passive recreation. Within the open space, there will be over 5 miles of natural surface walking trails, observation areas, wildflower meadows, and interpretive signs that will showcase the environmental and historic features of the property and the surrounding area.

Ed Merrifield, President Emeritus

Ed Merrifield served as President & Potomac Riverkeeper from 2003 to 2012. As a sailor on the Chesapeake Bay and the Potomac for over 25 years, Ed sought ways to make a real difference and find new approaches to protecting the health of our rivers and streams. This led Ed to come out of retirement in 2003 to work full-time on water quality as the Potomac Riverkeeper. As a forceful and effective leader at the grassroots, regional and state levels, he has advanced environmental policy and enforcement of clean water laws. Ed is an expert on Clean Water Act enforcement, especially on the Total Maximum Daily Load and National Pollution Discharge Elimination System permit issues. He served on the Maryland State Water Quality Advisory Committee and the Maryland Tributary Team from 1997 to 2012. Ed is considered one of the most influential environmentalists in the Chesapeake Bay region

During his tenure, Potomac Riverkeeper, Inc. evolved from an idea into a robust and effective organization, which filled a critical unmet need in the Potomac River region, allowing the people who treasure this unique national resource to protect it, primarily by direct action against polluters. Under Ed’s leadership, Potomac Riverkeeper, Inc. fulfilled its mission to stop pollution and restore clean water in the Potomac River and its tributaries.

What drove Ed: “When the Clean Water Act was passed in 1972, they wrote into it the goal that we’d be putting zero of our pollution into the water by 1985. We haven’t come close to that. That’s what drives me — getting to 1985.”

Highlights of enforcement actions:

• Stopped several sewage treatment plants from illegal discharges in West Virginia and Maryland.
• Stopped 60,000 pounds per year of illegal nutrient pollution from a Virginia sewage treatment plant.
• Forced Maryland to cleanup massive amounts of lead in Seneca Creek.
• Forced improvements at the watershed’s largest coal fly ash dump to stop toxic pollutants from leaching into local waters.
• Forced long overdue permits to be drafted for three major polluters in Maryland.
• Legally challenged the proposed general permits in Maryland and Virginia for construction stormwater, industrial stormwater, and municipal separate storm sewer systems for lack of enforceability and to call for increased public participation.
• Forced several federal agencies and the District of Columbia to start clean up of toxic pollution on land near the mouth of the Anacostia River.
• Forced the Maryland Department of Agriculture to allow public access to nutrient management plans for poultry farms.
• Convinced Virginia to apply the poultry waste land application rules to all using the waste.
• Petitioned the EPA regarding Maryland’s failure to properly administer and enforce the Clean Water Act.
• Decreased allowable limits of pollution by 25% in a Maryland sewage treatment plant
• Forced EPA to follow the TMDL (total maximum daily load) rules in DC resulting in daily testing for bacteria starting in 2013.
• Corrected illegal sediment pollution in many developments in Virginia, including one of the largest construction sites, the 495 HOT lanes.
• Stopped excessive pollution from a paper mill in West Virginia.
• Challenged permits for a proposed quarry in West Virginia that will threaten local drinking water supplies.
• Filed a lawsuit to clean up septic sewage discharges using an innovative approach under the Clean Water Act.
• Opposed attempts to include pollution trading in TMDLs, which was not intended under the Clean Water Act.

The Washingtonian named Ed Merrifield one of the most influential environmentalists, April 2008.

Ed is featured in Blue Legacy International’s 2010 film: Our Nation’s River a System on the Edge.

Ed provided background and hosted the film crew for Hedrick Smith’s 2009 Frontline documentary, Poisoned Waters.

In October 2012, Ed was honored in the U.S. House of Representatives for his service to the region as President of Potomac Riverkeeper.

Carol Ackerman

The protection, preservation, and improvement of water systems have been life-long passions for Carol Ackerman. Born the granddaughter of Art Flick, an internationally renowned fly-fisherman and New York state conservation policy advisor, and daughter of William Flick, a lead ichthyologist at Cornell University, her dedication to water conservation began as a child. Growing up in the Adirondacks, she had the privilege of working alongside her father in the fisheries laboratory, hatchery, lakes and ponds, studying the impact of acid rain on the water system. The important lessons she learned about global water systems at a young age continue to serve as her guiding principles.  This love for science translated into a Bachelor of Science degree in Medical Technology and a career in nuclear medicine at Suburban Hospital in Bethesda and Sibley Hospital in Washington, DC. As an avid environmentalist, Carol spent many years on Flathead Lake in Montana, making sure that her three children grew up with the same love for water. As a member of the Flathead Lakers, she was active in water quality management and volunteering at the Yellow Bay Research Station. To this day, Flathead Lake is still recognized as one of the most pristine water sources in the country. Locally, she was a board member for the Earth Conservation Corps, working to educate and empower youth to reclaim the Anacostia River. She was also a sitting board member for the Anacostia Riverkeepers. In her free time, Carol enjoys boating on our region’s beautiful waterways, cultivating her organic flower garden, and taking trail rides with her Morgan horse at the Bureau of Land Management’s idyllic 800-acre property in Mason Neck, Virginia.  She also takes every opportunity to continue to learn from her father, regularly visiting him on the Yellowstone River in Montana. Carol, her husband Steve and their three adult children are proud residents of the greater Washington region.
