State of the River Report Card
We regularly provide a progress update on the Anacostia River in part to create accountability for decision makers entrusted with the health of the river. This report card is your guide to how well our communities, environmental groups, and governments are meeting the goal of a fishable and swimmable Anacostia River, per the terms of the Clean Water Act. Provided here is a summary of the scientific data we have analyzed so that citizens and public officials can better understand the current state of the Anacostia River.
Our 2019 Report Card receives a failing grade of F, but it is the second highest score for the river despite the wettest year on record.
- 2018 was D.C.'s wettest year on record with an observed rainfall of 66.28 inches.
- Dissolved Oxygen and Chlorophyll a improved.
- Despite the excessive rains, the percent score for the entire Anacostia was the second best since AWS started issuing the State of the River Report Card.
- Trash Reduction, one of the qualitative measures, received a passing grade for the first time.
- Frequent torrential stream flows eroded stream banks sending tons of sediment to the river. This made the water cloudy and killed submerged aquatic vegetation (SAV).
- Fecal Bacteria (E. Coli.) comes from not only sewage but from animal feces washed into streams when it rains. The rainy year caused a worse Fecal Bacteria score.
The mission of the Anacostia Watershed Society is to protect and restore the Anacostia River and its watershed communities by cleaning the water, recovering the shores, and honoring the heritage. We believe that by working together with businesses, governments, faith-based organizations, and youth we can create sustainable solutions that improve our communities, empower our residents, and create economic prosperity that will result in a clean river. We want to change the way people think about the Anacostia and make the river a destination.
Challenges to Overcome
The most important parameters for a swimmable and fishable Anacostia River are fecal bacteria, toxics, trash, and uncontrolled stormwater. High fecal bacteria levels indicate that the water contains many types of disease-causing viruses, bacteria, and protozoa that can be hazardous to human health. We don't yet know the specific health risks associated with occasional exposure to the toxics (heavy metals, pesticides, and other chemicals) in the sediment in the river, but we do know that those contaminants are having a negative impact on fish populations and that removing or treating toxic sediment will be necessary for the river to sustain healthy fish safe for human consumption. Stormwater runoff is a major issue because runoff from impervious surfaces (e.g., roads, parking lots, driveways, roofs) brings numerous pollutants to streams and generates torrential stream flow, which causes streambank erosion and makes the water cloudy and inundates the river with sediment. The runoff also carries fecal matter, trash, and other pollutants to the river.
Data Sources and Disclaimers
- Data set: All available, professionally collected data was used. The data sets include those collected by DC government, Maryland Department of Natural Resources, United States Geological Survey, and the Anacostia Watershed Society.
- The data was compared with thresholds developed by Mid-Atlantic Tributary Assessment Coalition (MTAC) who created EcoCheck protocols - Sampling and data analysis protocols for Mid-Atlantic tidal tributary indicators.
- For the 2019 State of the Anacostia River Report, the data used for Remediation Indicator evaluations and Water Quality Indicator analysis were done for 2018.
- For trend analysis, data sets from 1984 to 2017 were used depending on the parameter and the section of the river.
- Note that no Report Card was issued in 2013 and that the one issued prior to that was dated 2011 (for the year representing most of the available data, rather than the year it was issued, 2012.)
