What You'll Learn
Boston Harbor's history of pollution
Boston Harbor, a natural harbor and estuary of Massachusetts Bay, has been an important port in American history since its discovery by Europeans in 1614. By 1660, almost all imports to the greater Boston area and the New England coast came through Boston Harbor, and the city's population exploded.
However, the harbor's pollution problem began in 1634 when sewage was dumped into the harbor and was expected to be washed away by the tides, which seldom happened. In the late 19th century, Boston citizens were advised not to swim in any portion of the harbor. Two of the first steam sewage stations were built in East Boston and Deer Island, but the harbor saw little improvement as raw sewage continued to be pumped into it.
In 1919, the Metropolitan District Commission was created to oversee and regulate the quality of harbor water, but this also proved ineffective. By the mid-20th century, the municipal wastewater treatment plants at Nut Island and Deer Island, constructed in 1952 and 1968, were engineered to treat 112 million and 343 million gallons per day, respectively. However, with flows exceeding their capacity, raw wastewater was often discharged directly into Boston Harbor, severely impacting recreational activities, marine habitats, and water quality.
The Boston Harbor Cleanup, motivated by the 1972 Clean Water Act, began in the 1970s and cost over $4 billion. It included the construction of the largest egg-shaped digesters of raw sewage in North America and a 7.5-mile tunnel bored under the harbor floor. The Deer Island Treatment Plant, implemented in the 1990s, played a crucial role in reducing pollution and increasing the population of marine organisms like amphipods.
Today, Boston Harbor is considered one of the cleanest in the nation, safe for fishing and swimming nearly every day. However, challenges remain, including beach closings after rainstorms due to bacteria-laden stormwater and combined sewer overflows. The MWRA is responsible for ensuring that cities, towns, hospitals, and industrial facilities pretreat their wastewater before it is discharged into Massachusetts Bay, but there are concerns about their enforcement of pollutant limits and treatment requirements.

The Clean Water Act
Boston Harbor, a natural harbor and estuary of Massachusetts Bay, holds historical significance in American history. However, by the 20th century, the harbor had become severely polluted due to the continuous dumping of raw sewage. The Clean Water Act of 1972 made this practice illegal, but it took until 2000 for the dumping to be completely halted in Boston with the full activation of a new plant.
The passage of the Clean Water Act was a bipartisan effort, and its implementation has led to significant improvements in water quality over the last 50 years. The Act has reduced direct pollution discharges, improved wastewater and stormwater infrastructure, and transformed Boston Harbor from one of the filthiest in the nation to one of the cleanest. The harbor is now safe for fishing and swimming, with billions of dollars invested in the surrounding real estate.
Despite the remarkable progress, there is still work to be done to protect Boston Harbor and ensure its accessibility and safety for all communities, especially those that have faced environmental injustice. Additionally, there are ongoing challenges with the treatment of wastewater and enforcement of pollutant limits by the Massachusetts Water Resources Authority (MWRA). Nevertheless, the Clean Water Act has been instrumental in the transformation of Boston Harbor, and continuous dedication to its principles is necessary to maintain and further this progress.

Political and legal intervention
The passage of the federal Clean Water Act in 1972 was a significant milestone in addressing the pollution issue. This legislation made it illegal to dump raw sewage into the harbor, but it took until September 6, 2000, for this practice to be completely halted in Boston with the full operation of a new plant. The Clean Water Act provided the legal framework and impetus for improving water quality nationwide, and it was a driving force behind the Boston Harbor cleanup efforts.
The Boston Harbor cleanup was also a triumph of law and public administration. A city solicitor, a state judge, a federal judge, and a federal administrator played pivotal roles in forcing the state to address the issue of raw sewage being discharged into the harbor. Their actions demonstrated the power of the legal system in holding officials accountable and driving change.
Additionally, political leaders eventually stepped up to tackle the problem. Notably, Governor Michael Dukakis played a leading role in creating the Massachusetts Water Resources Authority (MWRA) during his second and third terms (1983-1991). The MWRA has been instrumental in implementing the Deer Island Sewage Treatment Plant, which has significantly improved water quality in the harbor.
The Boston Harbor cleanup faced political challenges, with leaders initially slow to acknowledge the severity of the pollution issue. However, once the courts intervened and public awareness increased, state and local officials worked diligently to address the problem. The cleanup efforts were also a budgetary success, coming in under budget and largely on time.
In summary, the transformation of Boston Harbor from one of the filthiest to one of the cleanest in the nation was made possible through a combination of legal mandates, political leadership, and effective public administration. The political and legal interventions ensured that the necessary resources and attention were dedicated to restoring the health and beauty of this cherished natural resource.

The Boston Harbor Cleanup
Boston Harbor, a natural harbor and estuary of Massachusetts Bay, was once called the "dirtiest water in America". Improperly treated wastewater from homes, businesses, and hospitals impaired water quality, harmed local ecosystems and aquatic life, and caused health issues for Boston's residents. The water's pollution gained notoriety in popular culture, with The Standells' 1965 song "Dirty Water" referring to the state of the Charles River.
The effort to clean up Boston Harbor began in the 1970s, with the passage of the Clean Water Act in 1972, which made it illegal to dump sewage into the water. However, dumping of sewage in Boston Harbor continued until 2000, when the new Deer Island plant came fully online. The Metropolitan District Commission, created in 1919 to oversee and regulate harbor water quality, had failed to make significant improvements. The Boston Harbor Project in 1991 furthered the cleanup efforts, and by 1995-1997, full primary treatment was implemented at Deer Island.
Today, Boston Harbor is safe for fishing and swimming nearly every day, though beach closings still occur after rainstorms due to bacteria-laden stormwater and combined sewer overflows. The Conservation Law Foundation continues its efforts to ensure the coastal waters remain clean and habitable, as wastewater from homes, hospitals, and manufacturing facilities can still threaten the progress made. The MWRA is responsible for ensuring that cities, towns, hospitals, and industrial facilities pretreat their wastewater before it is discharged into Massachusetts Bay, but they have recently struggled to effectively set and enforce pollutant limits.

Ongoing challenges and maintenance
Despite the success of the Boston Harbor cleanup, ongoing challenges and maintenance efforts are still necessary to ensure the long-term health of the ecosystem. One persistent issue is the problem of combined sewer overflows, where heavy rains cause the sewage system to back up, resulting in the release of untreated wastewater into the harbor. This issue has not yet been fully addressed, and it continues to be a concern during and after rainstorms, causing beach closings due to bacteria-laden stormwater.
Another challenge is the presence of harmful pollutants, such as nitrogen, mercury, and zinc, which can enter the harbor from various sources, including wastewater, stormwater runoff, and agricultural activities. Nitrogen, in particular, is a significant pollutant, and the MWRA is planning to implement nitrogen removal facilities at Deer Island to address this issue. However, until these facilities are operational, nitrogen will continue to be a problem, impacting the health of marine life and the safety of humans who use the harbor for recreation.
The MWRA's role in enforcing pollutant limits and treatment requirements is also crucial. There have been concerns that the organization has not been effectively enforcing these standards, which could put the coastal waters at risk. Ensuring that all entities, including cities, towns, hospitals, and industrial facilities, are properly pretreating their wastewater before it is discharged into Massachusetts Bay is essential to maintaining the health of the harbor.
The cleanup of Boston Harbor has been a long and challenging journey, and maintaining its current state requires continued vigilance and proactive measures. While the harbor is now a safe and clean environment, the complex nature of coastal ecosystems means that ongoing monitoring and adaptive management are necessary to preserve this progress. The return of marine organisms and the increase in private investment along the waterfront demonstrate the positive impact of the cleanup efforts, but also underscore the need to stay vigilant against any regression.
