TEAM BUILDING: Anacostia River Boat Tour

6ff6e92a-9902-42b2-9131-92983141b51a-original

On July 26, the Nspiregreen team went on the Anacostia Watershed Society’s Anacostia Boat Tour as part of this quarter’s team building. This trip gave us a chance to see first-hand and learn more about the efforts being implemented to improve the health of the river. This was a great experience especially since we have been working on some projects related to the Anacostia River’s cleanup efforts.

The Anacostia River watershed is home to 43 species of fish, some 200 species of birds, and more than 800,000 people. The river flows through Montgomery and Prince George’s Counties in Maryland and past the Capitol Building in the District. The watershed is approximately 176 square miles and around 25% of its land lies in the District of Columbia. (Source: DOEE, February 15, 2018, EPA)

The Anacostia has been polluted by litter, raw sewage, stormwater runoff, and industrial waste since the 19th Century. However, in the past two decades efforts have been implemented to turn “The Forgotten River” into a “fishable and swimmable” water body as defined by the Clean Water Act. For example, the recently opened DC Water tunnel between the RFK Stadium and the Blue Plains Wastewater Treatment Plant is preventing millions of gallons of wastewater from entering the river, thus reducing the levels of bacteria. The District’s Department of Energy and Environment (DOEE) launched the “For a Cleaner Anacostia River” initiative aimed to clean the river sediments contaminated with industrial toxins including polychlorinated biphenyl’s (PCBs) and polycyclic aromatic hydrocarbon (PAHs).

Tour Highlights

Below are some highlights of our trip!

Rain, Rain, Rain…

There was a thunderstorm the night before the tour. In fact, this past July was one of the wettest Julys on record! The day we went, the river was yellow-colored and full of broken branches and litter. However, boats were out removing these items. Here is a picture of one of DC Water’s boats cleaning up litter.skimmerboat

Due to the high levels of precipitation, the river’s water level was really high. For this reason, we were not able to go under the Benning Rd bridge. The water was almost hitting the rail bridge! I heard the area north of this bridge has beautiful scenery and lots of wildlife. We will come back again!

The River is Improving

The water condition is getting better; wildlife and the levels of subaquatic vegetation have increased. The tour guide also told us that they are testing the use of mussels to clean the water. Fun fact an adult mussel can naturally filter about 10 gallons of water a day!

The Impacts of Heavy Rainfall on the Environment

The recent rain events this past week caused extreme flash flooding throughout the Northeast region. Parkways, streets, and metro or subway stations in New York, Washington D.C., Maryland, Virginia, and Massachusetts flooded leaving motorists, pedestrians, and commuters stranded and exposed to horrid conditions. I have become worrisome, not particularly of the increase in the intensity and frequency of torrential downpours, but of our current incapacity and mismanagement to handle all of this water. Every time we face intense rain, I have to think to myself: What towns or streets will face flooding? Who would want to walk through a transit system with murky water past their ankles with absolutely no knowledge of what bacteria or toxins lurk in that water? How much more can our water systems take from the toxic materials and untreated wastewater due to outdated infrastructures and sewer systems? Are we really placing public and environmental health, safety, and the quality of life for all as a top priority? Climate change has brought an increase of rain intensity and frequency. Rainfall intensity is the measure of the amount of rain that falls during a period of time while rainfall frequency is the amount of times it rains during a specified period of years. An increase in air and water temperature brings an increase of precipitation.  But we cannot isolate climate change, we must also pay close attention to the factors that it engages with. I can certainly name a few: presence of impervious surfaces, lack of greenspaces, outdated infrastructures and sewer systems. All of these factors exacerbate flooding and can be detrimental to our water systems.

Impervious Surfaces…

The large surface area of impervious surfaces like roads, parking lots, and roofs, that have replaced our natural landscape, do not allow water to infiltrate into the ground and speeds up the process of rainwater runoff entering the drainage systems. The runoff and the pollutants collected from impervious surfaces are either turning into floods or entering our water systems at a faster rate than it can be managed.

Lack of Greenspaces…

This kind of ties in with impervious surfaces. I think it’s safe to say that the more impervious surfaces we create, the less access to greenspace we have. Greenspace is extremely crucial. It provides benefits such as reducing and filtering polluted stormwater runoff, reducing soil erosion, and improving air quality. When we lack greenspace, we have to deal with a lot of preventable challenges. With a lack of soil and vegetation to absorb and filter the rainfall, we experience flooding and overloaded sewers. With a lack of vegetation, we experience an increase in air temperature (Note what I stated earlier about the effects of an increase in air temperature).

Outdated Infrastructures and Sewer Systems…

The outdated infrastructures and the combined sewer systems were built only to hold a certain capacity of rainfall. In addition, transit systems and roadways aren’t effectively updated or repaired. Poor management leads our infrastructures to dilapidate and become swamps. In the recent floods, water leaked through the concrete vaulted ceilings of the WMATA Capitol South metro station. In a few of New York’s subway stations, water entered through the ceiling and stairways flooding the stations. Combined sewer systems are typically found in older cities. When the capacity of the system is surpassed, the untreated wastewater and stormwater runoff flows into our waterways or can back up into buildings through the pipes or overflow from the storm drains onto the streets.

Now What…

With climate change there will be an increase of storm intensity and frequency, but how do we plan and design for worsening conditions? As the climate changes we must adapt our habits, the way we design, and our management of infrastructure. Stormwater management practices are used to reduce stormwater runoff, control flooding, reduce erosion, and improve water quality. These practices include green stormwater infrastructure (GSI), flood control reservoirs, and tunnels (SMART Tunnel in Kuala Lumpur, Malaysia and the Deep Tunnel in Milwaukee, Wisconsin addresses flash flooding and stores millions of gallons of overflow and sewage). Green infrastructure can be used to not only address our stormwater issues but to beautify our communities by creating healthy environments. Just imagine walking, driving, or riding your bike down a green street filled with a canopy of trees, native vegetation, GSI interventions, enhanced sidewalks, public art, and other street design features. A green street utilizes green infrastructure, improves public health and safety, and can even yield economic benefits.

We also have to contemplate all of the paved vacant lots or unused parking lots. For an example, malls all over the United States have an immense amount of parking.  What can we do with these spaces? These are opportunities to implement green infrastructure and green spaces for public spaces that can incorporate activities, pop-up spaces, farmers markets, etc.

In addition to the stormwater management practices, the timely repair and maintenance of infrastructure needs to be a requirement or else it will not function properly. Also, funding should be appropriately allocated to ensure that the proper solutions are identified and instated.

The strategies will not be the same in every location because the approach should be acclimated to the specific needs of that region based on in-depth analysis, research, and community engagement. However, with careful and purposeful consideration and action we can move in the right direction. I leave you with this: How can you be a part of the movement to create safe, equitable, and sustainable infrastructures and communities?

 Unless you have been living under a rock, you have seen the news and know the devastation Hurricane Harvey and its aftermath has caused in Southeast Texas. When we witness such tragedy on a large scale, we immediately begin discussing ways to prevent it; however, flooding is an everyday occurrence in many cities across the United States. While this flooding in the human environment may not be enough to blanket a city or trap people in their homes, it’s enough to destroy property; cause waterborne illnesses; cause loss of life; destroy crops; and impede access to essential public services such as ambulances and firetrucks. The aforementioned list is by no means exhaustive but a snippet to illustrate some of the impacts of flooding. Sadly, it doesn’t take a hurricane to have this impact. Heavy rainfall or even sustained rainfall over a long period of time can be just as destructive.

Unfortunately, climate change is causing more frequent and extreme weather events. Unless we take action to mitigate the damage caused by these wet weather events, we will see more devastation in our communities. As an environmental engineer who happens to work on stormwater management issues, here are a few of my thoughts on the topic.

1. Preservation of natural resources – Wetlands (marshes, swamps, bogs, ponds) are land areas covered by water that consist of plant and animal life. In the context of flood control, wetlands help protect against storm surges by serving as an intermediary between larger waterbodies and land. Unfortunately, development often destroys this natural barrier allowing more water to reach land and without filtration. Jurisdictions should include preservation of natural resources as they update their land use plans, comprehensive plans, and/or zoning laws.

2. Getting smarter about growth – During wet weather events, water is looking for a place to go. Water naturally seeps into the ground; however, many of our cities are covered in asphalt, concrete, and other impenetrable barriers. This surface water runoff can overwhelm our sewers and become stuck in areas where there is little flow. In addition, waterfronts are being developed with housing and commercial space without regards to rising water levels due to climate change. As this land erodes it will impact these places that are now high value corridors of living and entertainment. Despite these challenges, waterfronts are and will continue to be popular locations for development. Developments should consider sea level rise or consider new design techniques such as floodable buildings.

3. Increase in green infrastructure -Trees, rain gardens, green roofs, bio swales, pervious pavement, rain barrels and constructed wetlands are a newer approach to managing surface water runoff. Many urban areas are using green infrastructure as a tool to imitate the natural process that should occur after wet weather events by adding soils and other vegetation back into the ecosystem. Green infrastructure has to be a part of a larger strategy to effectively minimize the impact of wet weather as well as place making in communities.

4. Increase and maintain gray infrastructure – Poor drainage, lack of maintenance, infrastructure not designed for high density populations are all issues impacting our existing gray infrastructure such as storm drains, storm sewers, holding tanks, dams and levees. In fact, both dams and levees received a grade D on the American Society of Civil Engineers 2017 Infrastructure Report Card. New gray infrastructure as well as the maintenance of older infrastructure are important components in preventing the outcomes we often witness in wet weather events.

The damage and destruction that we witnessed post Katrina, Sandy and now Harvey are not isolated to these extreme wet weather events. Until we extend our conversations and more importantly our action to maintenance and prevention, we will continue to play Monday morning quarterback. Unfortunately, it’s more than a football game at stake. Lives depend on it. America, we have a problem!

P.S. Extreme wet weather events are occurring globally but for the purposes of  making this blog brief, I limited the issue to the United States of America.
