What You'll Learn
The Schuylkill River has a history of industrial pollution
The Schuylkill River has a long history of industrial pollution, dating back to the 19th and 20th centuries. During this period, the river was plagued by pollution from nearby iron and mining industries, as well as railway developments. The situation became so severe that the river is known to have caught fire on multiple occasions, including a fatal incident in 1892 caused by a film of oil on the water's surface.
In more recent times, efforts have been made to restore and rehabilitate the river. Fairmount Park was established in 1812 as an early response to water quality concerns. The passing of the Clean Water Act in 1972 provided further protections, and the river was designated as a Pennsylvania Scenic River in 1978.
Despite these measures, the river continues to face pollution challenges. Heavy rains can cause wastewater and stormwater to overflow into the river, leading to high levels of bacteria and a discoloured appearance. Plastic pollution is also a significant issue, with microplastics detected in 100% of samples taken from Pennsylvania's rivers. The Philadelphia Water Department removes 44 tons of trash, including plastic waste, from a 32-mile stretch of the Schuylkill and Delaware Rivers annually.
However, there are signs of improvement. The river has been described as having made a "historic recovery," with increased wildlife and recreational activities. Environmental groups and city council representatives are working together to further enhance the river's health and explore opportunities for recreation. The Green City program, introduced in 2011, aims to significantly reduce pollution by 2036, although climate change poses ongoing challenges.

Climate change impacts pollution-reduction efforts
The Schuylkill River in Pennsylvania has been plagued by industrial pollution and mining silt since the 19th century. While the river has made significant strides towards recovery, climate change impacts continue to pose challenges for pollution-reduction efforts.
The river's pollution reduction efforts have been impacted by heavier storms resulting from climate change. As the city works to prevent stormwater from flowing into the river, the volume of water continues to rise due to increased storm intensity. This has led to an increase in the amount of raw sewage and stormwater pouring into the river, with an estimated 14 billion gallons of untreated sewage and rainwater flowing into the Schuylkill River annually.
Urban sprawl and suburban development have also contributed to the increase in dissolved solutes in the river. The expansion of impervious areas in watersheds reduces the infiltration capacity of land cover, leading to increased runoff and higher levels of pollutants entering the river. This has been exacerbated by agricultural development, which has been identified as an accelerator of bicarbonate export, impacting the river's water quality.
Climate change scenarios predict a substantial increase in the frequency of streamflow targets not being met in the Schuylkill River. Under the most extreme climate scenario, there could be up to 82 additional days each year where the streamflow target is not achieved. This reduction in streamflow is driven by the impact of intensifying precipitation, rather than changes in land use.
Despite these challenges, efforts to combat pollution in the Schuylkill River are showing progress. The river has seen a historic recovery, with improved habitats for fish, birds, turtles, mussels, and recreational opportunities for people. The implementation of environmental policies and management strategies has positively impacted water quality in urban and suburban areas, even as rural areas continue to struggle with worsening water quality.

Plastic pollution harms wildlife and contaminates drinking water
The Schuylkill River has been plagued by industrial pollution and mining silt in the past. While the river has made a significant recovery, it continues to face issues with plastic pollution.
Plastic pollution is a pressing environmental concern, with plastic waste causing harm to wildlife and contaminating drinking water. Plastic pollution has a direct and deadly impact on wildlife, with thousands of marine animals, such as seabirds, sea turtles, seals, and other marine mammals, dying each year due to ingesting plastic or becoming entangled in it. According to research, approximately half of the sea turtles worldwide have ingested plastic, often mistaking it for food, leading to choking, internal injuries, and starvation.
Endangered species, such as the Hawaiian monk seal and Pacific loggerhead sea turtle, are among the nearly 700 species affected by plastic litter. In addition to marine life, land animals are also affected. There have been reported cases of elephants, hyenas, zebras, tigers, camels, and cattle accidentally consuming plastic waste, resulting in intestinal blockages and fatalities.
Plastic pollution also poses a risk to human health. Microplastics, tiny plastic particles formed when plastics break down over time, have been detected in bottled water, tap water, and well water worldwide. These microplastics can enter water sources through various pathways, such as laundry wastewater, rainwater runoff, and plastic waste in landfills. The presence of microplastics in drinking water has raised concerns about potential health risks, as these particles can be ingested or inhaled, potentially affecting delicate organs and causing long-term health issues.
The extent of plastic pollution is not limited to a specific region or body of water. Studies have shown that not a single square mile of surface ocean anywhere on Earth is free from plastic pollution. With the continued increase in plastic production and consumption, the problem is projected to worsen, emphasizing the urgent need for action to address this global crisis.

The river is unsafe for swimming due to high bacteria levels
The Schuylkill River has a long history of pollution, dating back to the 19th and 20th centuries when industrial pollution and mining silt severely degraded its water quality. While the river has undergone significant restoration efforts, it continues to face pollution challenges today.
One of the major issues affecting the river's water quality is the presence of high bacteria levels, which can make it unsafe for swimming and other recreational activities. Heavy rainfall can cause stormwater to flow into the river, bringing with it runoff from agricultural and urban areas. This runoff can contain animal waste, and in the case of particularly strong storms, it can even include human waste if sewer systems become overwhelmed. As a result, the river tends to exhibit high bacteria levels after storms, indicated by its characteristic "chocolate milk" colour.
The high bacteria levels in the Schuylkill River pose a potential health risk to those who come into contact with the water. While the river typically recovers and becomes clean again within 48 hours, the presence of bacteria can have detrimental effects on both human health and the ecosystem. The bacteria can indicate the presence of pathogens, which can cause various illnesses, including gastrointestinal issues and skin infections.
In addition to the health risks, the high bacteria levels in the river also impact the ecological health of the Schuylkill River. Bacteria can deplete oxygen levels in the water, creating dead zones where aquatic life cannot survive. This disruption to the ecosystem can have far-reaching consequences, affecting everything from aquatic plants and animals to the birds and other wildlife that depend on the river as a food source.
To address the issue of high bacteria levels, several initiatives have been implemented. The Green City program, introduced in 2011, aims to significantly reduce pollution by 2036. However, environmentalists argue that more immediate action is needed, particularly in managing stormwater and reducing sewage overflow. The Restoring the River Action Team, a collaborative of nonprofits, is advocating for more aggressive measures to be taken by the PWD to address the issue.
While the Schuylkill River has made significant progress in terms of restoration, the presence of high bacteria levels continues to be a concern. Until the issue is effectively addressed, the river may remain unsafe for swimming and other activities that involve direct contact with the water.

Restoration efforts are making a positive difference
One notable initiative is the Green City program, introduced in 2011, which aims to significantly reduce pollution in the river by 2036. While the program faces challenges due to climate change and increasing stormwater runoff, it has made progress in reducing pollution levels. The Restoring the River Action Team, a collaborative of nonprofits, is actively working to address these issues and push for additional measures to be taken.
The Schuylkill River has also benefited from funding left for that purpose in Benjamin Franklin's will. This funding has supported restoration efforts and helped to improve the ecological health of the river. As a result, the river has come alive with fish, birds, turtles, mussels, and other wildlife. The riverbanks have also been transformed, with the development of trails, fishing piers, and docks, enhancing recreational opportunities for the community.
In addition to these efforts, the Philadelphia Water Department (PWD) has utilized skimmer boats to remove floating trash and plastics from the river. Each skimming vessel collects 1.1 tons of plastic per year, significantly reducing the amount of plastic pollution in the water. The PWD's efforts are complemented by the work of nonprofit organizations such as Upstream Alliance and Riverways, which advocate for further pollution reduction and monitor the ecological status of the river.
The Stroud Water Research Center, in partnership with other environmental organizations, has launched an interactive ArcGIS StoryMap project to connect residents and communities with the river. The project aims to raise awareness of the river's scenic and recreational potential while also addressing local perceptions and concerns about water quality. This initiative has fostered a greater sense of stewardship among the community and encouraged further efforts to protect and restore the river.
While challenges remain, the collective efforts of government agencies, nonprofits, and community organizations are making a positive difference in the restoration of the Schuylkill River. Through continued dedication and collaboration, it is hoped that the river will continue to thrive and serve as a valuable ecological, recreational, and scenic resource for the region.
