What’s keeping your hometown river from achieving a A grade

We've made a lot of progress when it comes to stopping polluters from spoiling our rivers. Yet our latest Potomac River Report Card shows that our hometown river is at a precarious tipping point.

There's a reason why our children still cannot safely swim in the Potomac River and fishermen are cautioned against eating their catch: There are still plenty of ways to legally pollute our rivers.

But knowledge is power! Learn five ways* pollution is legally entering our waters and what you can do to right the course for the Potomac.

*We left out one egregious example: Hundreds of millions of gallons of raw diluted sewage enter the Potomac River every year through Combined Sewage Overflows (CSOs). While it is legal for now, DC Water is cooperating with the EPA and will eliminate nearly all CSOs by 2030. The city of Alexandria, VA has a similarly problem but is working to reduce its CSO by 95% by 2025.

Pave over forests like it's no big deal

Every day, we lose 70 acres of forest in the Chesapeake Bay region to development and gain new plazas, parking lots, and housing developments.

We need places to live and shop, but we also need outdoor areas to enjoy on the weekend and healthy trees to keep our drinking water sources clean and safe. (Not to mention, forests are one of our best defenses against the climate emergency.)

The barren land left in the wake of bulldozers is ill-equipped to absorb rainwater, creating excessive runoff that pollutes our drinking water sources, spoils fishing grounds, and destroys wildlife habitat. Pollution from urbanization is so bad that it continues to be the fastest growing source of pollution in the Potomac and Chesapeake Bay.

Clean water solution: Forested lands produce the cleanest water flowing into our streams and rivers. Protecting large swaths of woodlands is critical to safeguarding water quality in the Potomac and Chesapeake Bay.

We must urge city and county planners to create forward-thinking conservation plans and support Potomac Conservancy and other land trusts who work with communities to permanently protect riverside forests.

We also need to safeguard public parks, forests, and open spaces from any encroachments on their public access or protections.

Let cattle go to the bathroom in our drinking water sources

It may sound nice to allow cows to splash around in streams, but it’s actually not good for their health or the health of your water.

Livestock animals traveling through waterways destroy the protective buffers of plants and trees, spreading dirt and mud into the waters. Worse still, when cows are allowed access to creeks and streams, they spread disease, hormones, e-coli, and other bacteria through their feces. That means more sick cows, especially vulnerable calves, and more pollution in our waters.

Yuck.

Polluted runoff from agricultural lands, including cow and chicken feces, remains the single largest contributor of pollution in the Potomac River and the Chesapeake Bay.

Clean water solution: This type of pollution is largely unregulated, which means voluntary, private efforts are the main way to make progress.

Farmers can keep their cattle healthy and our waters safe by fencing off streams and using water troughs to keep their animals hydrated. Several state and federal programs fully cover the costs of installing these measures, called best management practices (BMPs).

Potomac Conservancy works one-on-one with small family farms to provide landowners with the expertise and resources they need to install BMPs and keep pollution out of upstream waters.

Give developers the OK to strip shorelines bare

Just 45 miles upstream from our nation’s capital, developers in Loudoun County, Virginia, can legally cut down trees along the Potomac River and local streams.

Without legal repercussions in the county, Trump National Golf Course was allowed to clear cut 1.5 miles of trees along the Potomac in 2010. This past winter, they cut down even more and dumped the debris right in the river!

Bare, eroding shorelines let loose harmful runoff and sediment into our waterways, ruining nearby fishing grounds and polluting the Potomac River, the source of drinking water for you and over 5 million residents.

Clean water solution: Trees are nature’s best Brita filters. They help control polluted runoff by soaking up excess rainwater, filtering out land-based pollution, and stabilizing stream banks with their root systems. Their shade keeps water temperatures cool and they provide important habitat for fish and local wildlife.

Stripping trees and natural protections along waterways is illegal in most jurisdictions, but Loudoun County’s elected leaders deem it acceptable. Stand up for clean water and urge your local leaders to protect tree buffers along our streams!

Give the thumbs up to sprawl

As the region makes room for 2.3 million new residents, sprawl is creeping into rural areas and paving over agricultural and forested lands at a rapid pace.

When elected leaders and planners sign off on sprawl, it leads to shrinking forests, weakened natural flood protections, and greater pollution levels in our local streams and rivers — not to mention increased traffic, larger school classroom sizes, and higher costs of living.

This spells bad news for our waters. Polluted runoff from expanding urban areas is the fastest growing source of pollution to the Potomac River and Chesapeake Bay.

Clean water solution: Tell your local decision-makers to say no to sprawl and yes to river friendly growth! By embracing smart planning approaches, communities can responsibly manage growth and protect healthy lands and waters. Urge your local elected leaders to support clustered areas for mixed-use development, protected zones for forested and public lands, and affordable nature-based solutions that improve local water quality and beautify communities at the same time.

Decorate the river with our trash

Littering is actually illegal in many places (thankfully!), but you wouldn’t know it by looking at our rivers after big rain events.

Small pieces of trash add up quickly to an enormous source of pollution found in our local waters. While some of this pollution is due to irresponsible river users, much of it finds its way to the water by accident – through polluted runoff.

During Alice Ferguson Foundation’s 2018 Potomac Watershed Cleanup Day, volunteers across the region removed over 346,000 pounds of trash. That’s the equivalent of removing 26 African elephants worth of trash from the Potomac!

Litter’s harmful impact goes beyond displeasing aesthetics. It leaches toxins as it breaks down, puts wildlife in danger, disturbs water flow in small streams, and costs local jurisdictions tens of thousands of dollars annually in removal efforts.

Clean water solution: On your next outdoor adventure, do the Potomac a solid and bring a reusable water bottle, pick up your dog toys, and collect and remove trash that you bring with you.
