Water Pollution In Delaware: A Growing Concern?

Water pollution in Delaware has been a concern for over 200 years, with the river being considered an open sewer for public and industrial waste during World War II. While the Clean Water Act and the formation of the Delaware River Basin Commission have helped to improve water quality, Delaware still has the highest percentage of impaired rivers and streams in the US. The state's water and sewage infrastructure has struggled to keep up with population growth, and nonpoint source water pollution, such as agricultural runoff, remains a significant issue. The Environmental Integrity Project has deemed 97% of Delaware's waterways to be polluted.

Delaware's water pollution is the worst in the US

The history of water pollution in Delaware dates back to the early 18th century, with the Delaware River being a significant source of pollution. By the 20th century, the river was notoriously foul-smelling and polluted, with rampant industrial and public waste. The implementation of the Clean Water Act in 1972 brought about significant improvements, and the creation of the Delaware River Basin Commission in 1961 helped address water quality issues. However, despite these efforts, Delaware continues to struggle with water pollution, particularly from nonpoint source pollution, which includes agricultural runoff and wastewater discharge.

The Environmental Integrity Project report highlights the failure to adequately protect public health and the environment in Delaware. The report calls for stronger regulations and enforcement of existing laws to address the persistent issue of water pollution in the state. The Clean Water Act, while successful in reducing raw human waste and industrial discharges, has weaknesses that have left several waterways tainted. Closing loopholes for agricultural runoff and other non-point sources of pollution is essential to improving water quality in Delaware.

The impact of water pollution in Delaware is evident in the state's rivers and streams, with high levels of pollutants such as fecal bacteria, nitrogen, phosphorus, pesticides, PCBs, and dioxins. These pollutants have led to water quality issues that affect both the environment and, to a lesser extent, humans. While municipal water sources remain mostly unaffected due to sanitation processes, private wells and natural bodies of water, such as rivers and lakes, bear the brunt of the pollution.

Delaware's water and sewage infrastructure have also struggled to keep up with the state's residential and commercial growth, contributing to the water pollution crisis. The state's ranking as the "Chemical Capital of the World" further exacerbates the problem, with waste chemicals from production plants entering the environment and impacting water quality. Overall, Delaware's water pollution is a complex issue that requires a comprehensive approach involving stronger regulations, improved infrastructure, and a focus on reducing nonpoint source pollution to protect the health and well-being of its citizens and natural ecosystems.

Pollution from farms and sewage

Delaware has been ranked among the states with the highest levels of waterway pollution. The state's rivers and streams are contaminated with pollutants such as fecal bacteria, nitrogen, phosphorus, pesticides, PCBs, and dioxins. The Environmental Integrity Project evaluated waterways classified as impaired, unfit for swimming, recreation, aquatic life, fish consumption, and drinking.

Agricultural runoff is a major source of pollution in Delaware's waterways. The state has a high concentration of poultry farms that spread large amounts of waste on fields, which then runs off into streams. The Environmental Protection Agency (EPA) has identified polluted runoff from farms and suburban and urban areas as the primary source of impairments in the state's waters. The Environmental Integrity Project is calling for federal and state agencies to hold farms accountable for agricultural runoff and enforce regulations to reduce pollution.

In addition to agricultural runoff, sewage infrastructure issues also contribute to water pollution in Delaware. The state's sewage systems have struggled to keep up with the demands of a growing population, leading to overflows and leaks that contaminate nearby waterways. The Clean Water Act, implemented in 1972, has helped reduce raw human waste and industrial discharges into rivers and streams. However, there are still weaknesses in the law that need to be addressed to fully protect the state's waterways.

Overall, pollution from farms and sewage is a significant contributor to Delaware's water pollution problem. The state is working to address these issues through various initiatives, such as upgrading wastewater treatment facilities and adopting comprehensive water quality standards. However, more needs to be done to reduce the impact of agricultural runoff and improve the state's sewage infrastructure.

The Clean Water Act and its impact

The Clean Water Act (CWA) was passed in 1972 to address water pollution in the United States. The Act provided the federal government with the authority to regulate pollution and fund improvements to wastewater infrastructure. The CWA has had a significant impact on improving water quality in Delaware, which has historically been one of the most polluted waterways in the country.

Prior to the CWA, the Delaware River was heavily polluted due to rapid population growth, industrial activities, and agricultural runoff. The river was considered an open sewer, with high levels of trash, raw sewage, and factory discharges. This pollution led to severe waterborne illnesses and a decline in migratory fish populations. The river's water was so foul that it would turn the paint of ships brown and people were sickened by the smell.

The CWA provided funding for upgrades to wastewater treatment plants and helped reduce raw human waste and industrial discharges into the river. The Act also ushered in an era of biological science for treating wastewater, using microbes and oxygen to eliminate bacteria in a controlled setting. This process involves using microbes to consume pollutants, with any remaining solids being removed and turned into fertilizer or used to generate methane.

The impact of the CWA on the Delaware River has been significant. According to Philadelphia’s former water commissioner, Deb McCarty, the river has been transformed from a “stinky ugly mess” into a year-round attraction for recreation and tourism. The river's water quality has improved, and fish and aquatic life have returned. The Delaware River Basin Commission (DRBC), formed in 1961, also played a crucial role in regulating and abating pollution in the basin waters before and after the passage of the CWA.

However, despite the successes of the CWA, there are still challenges to ensuring clean water in Delaware. The state continues to struggle with polluted runoff from farms and suburban and urban areas, which contributes to high levels of pollutants such as fecal bacteria, nitrogen, phosphorus, pesticides, PCBs, and dioxins. Environmental advocates also argue that the CWA needs to be strengthened to address loopholes for agricultural runoff and other “non-point” sources of pollution.

Nonpoint source water pollution

Delaware has a serious problem with water pollution. According to the Environmental Integrity Project, the state has the highest percentage of impaired rivers and streams in the US. The report found that 97% of Delaware's 1,104 miles of assessed waterways are impaired for one or more uses, and 100% of the state's 775 square miles of assessed estuaries are impaired. The sources of this pollution are varied, but nonpoint sources are a significant contributor.

The Delaware Department of Natural Resources and Environmental Control (DNREC) has a Nonpoint Source Program that provides funding for projects designed to reduce nonpoint source pollution in the state. The program also hosts educational events and workshops to provide residents with information to help protect the state's aquatic resources. However, some activists and environmental advocates argue that more needs to be done to address nonpoint source pollution in Delaware, particularly in regulating agricultural runoff.

The Clean Water Act, first implemented in 1972, has played a role in reducing some point sources of pollution, such as raw human waste and industrial discharges. However, it has been criticised for not adequately addressing nonpoint sources of pollution, which have been left largely to voluntary measures. Closing the loophole for agricultural runoff and other non-point sources of pollution is essential to improving Delaware's water quality and protecting public health.

Delaware's water quality crisis

The Environmental Integrity Project report revealed that 97% of Delaware's assessed waterways are impaired for one or more uses due to pollution. This includes the state's rivers and streams, which are contaminated with pollutants such as fecal bacteria, nitrogen, phosphorus, pesticides, PCBs, and dioxins. The report also highlighted that 100% of the assessed estuaries in Delaware are impaired, affecting the zones where freshwater and saltwater mix along the coast.

The main sources of pollution in Delaware's waterways are attributed to agricultural runoff, industrial activities, and suburban and urban areas. The state's designation as the "Chemical Capital of the World" has contributed to the issue, with waste chemicals from production plants and agricultural practices entering natural water sources. This has led to eutrophication, a process that destroys ecosystems by depriving them of sunlight and oxygen, ultimately choking the life out of aquatic habitats.

While the Clean Water Act, implemented 50 years ago, has made significant progress in reducing pollution from point sources, such as smokestacks or sewer pipes, the legislation has fallen short in addressing nonpoint source water pollution. Nonpoint sources, such as agricultural runoff and wastewater seepage, are more challenging to regulate due to their indirect and widespread nature. This has resulted in ongoing water quality issues in Delaware, with many residents lacking access to clean water, particularly in poor and minority communities.

The Delaware River, in particular, has a long history of pollution. Once considered an open sewer for public and industrial waste, the river has undergone improvements due to the efforts of the Delaware River Basin Commission and the implementation of the Clean Water Act. However, recent studies have identified the Delaware River as the leading source of macroplastics pollution in North America, posing a significant hazard to aquatic life and the oceans.
