I’ve been researching unusual environments for family trips, and I recently learned about the Gowanus Canal in Brooklyn, New York City. It’s a place with a fascinating history that has transformed from an industrial waterway into an EPA Superfund site. I found that while it’s a heavily polluted area, scientists are discovering surprising things about the life that thrives there, which might offer new ideas for environmental cleanup. It’s a complex story, and I’m trying to understand how these discoveries could inform potential visitor interest or simply expand our understanding of nature’s resilience.
Gowanus Canal A Superfund Site
The Gowanus Canal’s story is one of industrial past. It was created in the mid-1800s to help ships move goods. Factories like coal yards, gas plants, and chemical facilities were built alongside it, and sadly, they released waste and toxic materials directly into the water. This included things like coal tar and waste from slaughterhouses.
Over many years, these industrial activities created a layer of toxic sediment at the bottom of the canal. This sludge has been nicknamed “black mayonnaise” because of its appearance and consistency. Studies by the EPA have identified various harmful substances in this sediment, such as PCBs, PAHs, volatile organic compounds (VOCs), and heavy metals like mercury, lead, and copper. These pollutants have also seeped into the original creek beds that existed before the canal was built.
Why Study This Canal Ecosystem
When the EPA announced plans to clean up the Gowanus Canal, starting in earnest in 2020, some people questioned what would happen to the ecosystem. The remediation plans involve removing a large amount of the contaminated sediment and then covering the rest with concrete. Elizabeth Hénaff, who has a background in biology and computer science and explores how organisms interact with their environments, was particularly interested in understanding what kind of ecosystem, if any, existed in the canal.
The idea was that if such an intervention were proposed for a natural body of water, it might be seen as destructive. This led to the question: what truly lives, or survives, in the Gowanus Canal? Initial observations might not show much visible life, but Hénaff and her colleagues decided to investigate the canal’s sludge further through genetic analysis.
Discovering Microscopic Life
Her work involved collaborating with the Gowanus Dredgers Canoe Club, an organization known for its advocacy and canoe trips on the canal. Wearing protective gear, Hénaff and her team took canoe trips to collect samples of the canal’s water and sludge. They also brought a significant amount, about 300 gallons, to a public art space called BioBAT Art Space in Sunset Park for an exhibition.
What they discovered was quite remarkable. Despite the canal being too toxic for most larger organisms like fish, crabs, or birds, it is teeming with microbial life. These microorganisms are not just surviving; they are thriving within this chemical-laden environment. They have developed ways to break down the toxic compounds they are exposed to.
Microbial Adaptations
Microorganisms live and reproduce very quickly, with generations happening in just a matter of minutes for us. Over countless generations, the microbes in the Gowanus Canal have evolved to adapt to their harsh surroundings. These extremophiles, or organisms that thrive in extreme conditions, have learned to process the harmful chemicals.
For pollutants like PCBs and PAHs, the microbes break them down into less harmful forms. Heavy metals, which cannot be broken down further, are handled by the microbes in a different way. They have developed the ability to make these metals less bioavailable, meaning they are less likely to be absorbed by other organisms, which helps protect themselves and the surrounding environment.
Community Collaboration
An important finding of Hénaff’s research is that these microbes are most effective when they work together. When isolated, individual microbes might not be able to perform these complex functions as capably as they can when they are part of a community. This collaboration allows them to carry out the necessary breakdown of toxins and management of heavy metals more efficiently.
Implications for Environmental Remediation
The discovery that the Gowanus Canal is home to “pollution-eating” microbes has significant implications. These tiny organisms have, on their own, developed sophisticated biological solutions to the contamination they face. This understanding could be valuable for future remediation efforts in other polluted areas worldwide.
However, it’s also important to consider the scale of the problem. While microbes evolve quickly, they are very small. The rate at which they could naturally clean up the entire canal is extremely slow. For a densely populated area like Brooklyn, waiting for natural microbial cleanup is not a feasible or safe option. The health and safety of New York City residents are paramount, and exposure to these chemical contaminants must be prevented.
The Dredge-and-Cap Solution
Given the challenges and the need for immediate action, the EPA’s plan to dredge and cap the Gowanus Canal is likely the most practical approach. This involves physically removing the contaminated sediment and then covering the remaining material to seal it off.
While the physical cleanup proceeds, research into the canal’s microbial communities continues. Hénaff’s work, which blends science and art, explores these organisms in new ways. The 300 gallons of canal water and sludge brought to the BioBAT Art Space were central to an art exhibit called “CHANNEL,” created by a team including Hénaff. This exhibit allowed the public to observe the microbes and their growth patterns over time in a different setting than a laboratory.
Art and Science Intersect
In a laboratory setting, scientists often aim to control organisms to study them under specific conditions. The art exhibit offered a different kind of interaction, allowing the microbes to grow in a less controlled environment. This created a more direct relationship with the organisms being studied.
Observing the microbes over a year in the exhibit space led to unexpected discoveries. There were visible changes, like the formation and dissipation of microbial biofilms—complex, three-dimensional structures. There were also cycles of algal blooms and collapses, illustrating the dynamic nature of this microbial ecosystem.
What Can We Learn from Biofilms
These biofilms piqued Hénaff’s interest for future scientific inquiry. Biofilms are fascinating because they show how single-celled organisms can assemble into larger, organized structures. These structures can exhibit a division of labor among different species, almost like organs in a larger organism. Understanding who is doing what within these communities and how they collaborate to perform complex functions is a key area of research.
The hope is that studying these microbial communities might offer insights that could help address future environmental disasters. Even as the physical cleanup of the Gowanus Canal proceeds with its dredging and capping, the knowledge gained from its unique microbial inhabitants continues to live on through scientific and artistic exploration.

Finding places to eat that cater to children is always a priority for me. New York City has an incredible range of restaurants, from casual diners to more formal establishments. Many places offer kid-friendly menus or are generally accommodating to families with younger children.
I often look for restaurants that have a relaxed atmosphere. This helps when dining with active children. Casual eateries or pizzerias are often good choices. I also appreciate places that have outdoor seating, as it can sometimes make the dining experience easier when managing younger children and their energy levels.
Where can families stay comfortably
When looking for accommodations, I prioritize places that offer comfort and convenience for a family. Hotels that have larger rooms or suites can be very helpful, providing enough space for everyone. I also look for amenities that make traveling with children easier, such as on-site laundry facilities or proximity to parks and family-friendly attractions.
Considering the location is also important. Staying in an area that is well-connected by public transportation makes it easier to get around the city without the stress of constant driving or parking.
