For more than a decade, an industry dumped enormous volumes of hazardous waste into the old canal of Niagara Falls; years later, chemicals reached the soil, groundwater, backyards, basements, sewer systems, and nearby streams.
An abandoned canal project in Niagara Falls, New York, ended up transformed into an industrial dump for over 21,000 U.S. tons of chemical waste.
Decades later, Love Canal would become the site of one of the most well-known environmental crises in the United States, leading authorities to evacuate around 950 families from the area.
Between 1942 and 1953, Hooker Electrochemical Company, later linked to what is now Occidental Chemical Corporation, used the site for disposal of hazardous chemicals. The waste was buried in an area of approximately 16 acres, later covered with soil.

Elementary Students Pioneer Sustainable Bioinput from Charcoal Production Waste
Over the years, a school and numerous homes emerged nearby. The problem escalated when contaminants began reaching the soil and groundwater, and chemicals were found beyond the original boundaries of the dump.
Love Canal Received Over 21,000 Tons of Chemical Waste
Before becoming one of the most well-known environmental cases in the United States, Love Canal was part of a project initiated in the Niagara Falls area for the construction of a canal associated with hydropower production.
The project was never completed. The abandoned excavation partially filled with water and had recreational use before taking on an entirely different purpose.
According to the official Love Canal profile maintained by the U.S. Environmental Protection Agency, the EPA, between 1942 and 1953, Hooker Electrochemical Company used the abandoned canal to dispose of over 21,000 short tons of hazardous chemicals.
Documentation later published in the Federal Register described the volume as approximately 22,000 short tons of chemical waste packaged in drums or discarded in liquid form.
Among the materials mentioned were polycyclic aromatic hydrocarbons, halogenated organic compounds, pesticides, chlorobenzenes, and dioxin.
In 1953, the old dump was covered with soil. The area was transferred to the Niagara Falls Board of Education, responsible for the local education system, and later an elementary school and several homes were built near the covered landfill.
Homes and School Built Near the Former Landfill
For years, a significant amount of chemicals remained buried under a region that was undergoing urban development.
The crisis did not emerge suddenly. The EPA notes that complaints regarding odors and waste began surfacing in the area as early as the 1960s and increased during the following decade.
In the 1970s, the combination of buried waste and changes in groundwater levels exacerbated the issue. Federal documentation indicates that periods of exceptionally high precipitation raised the water level within the landfill.
This movement allowed contaminants to spread laterally through the surface soil and into areas where urban service structures were installed. Chemicals ultimately made their way into the basements of nearby homes.
There was also migration into sewage and drainage systems that extended beyond the former landfill’s boundaries. Some of these structures discharged into nearby streams connected to the Niagara River system.
The EPA summarizes the problem by stating that the buried drums leaked and contaminated the soil and groundwater. Studies conducted by state and federal authorities also identified toxic chemicals circulating through sewage networks and reaching nearby waterways.
Health Emergency Changed Residents’ Routine
In 1978, the situation escalated from a local environmental issue to an emergency requiring immediate action.
The New York State Department of Health implemented measures related to the population of Love Canal. On August 2, 1978, an order from the state health commissioner recommended, among other actions, the temporary removal of pregnant women and children under two years of age from the areas considered most exposed.
A special report by the New York State Department of Health indicates that the operation to assist families began immediately after the state order.
That same month, then-President Jimmy Carter issued the first federal emergency declaration for Love Canal. The action opened the door for resources allocated to manage chemical waste and the relocation of residents from properties directly adjacent to the landfill.
Federal documentation lists 239 properties in this initial area surrounding the landfill. However, the response would expand two years later.
Approximately 950 Families Were Relocated
In May 1980, Jimmy Carter issued a second emergency declaration. This time, a comprehensive emergency area was designated, encompassing approximately 350 acres around Love Canal.
The measure authorized US$ 20 million in federal funds for the acquisition of homes from affected residents, with financial participation from the state of New York.
The human impact is clearly reflected in the numbers recorded by the government.
According to the document published in the Federal Register regarding Love Canal, the Federal Emergency Management Agency, FEMA, allocated the resources and, along with the New York State Department of Environmental Conservation, participated in relocating approximately 950 of the more than 1,050 affected families.
The families left an area of approximately ten blocks around the landfill. Some individuals within the official emergency area chose to stay and were authorized to remain on their properties.
Houses near the landfill and the 99th Street school were subsequently demolished. The federal government and the state of New York also purchased, demolished, or restored properties impacted by the crisis.
Contamination Required Decades of Work
The work did not end with the removal of the residents.
Measures taken included installing systems to collect contaminated liquids, treating leachate, covering polluted material, and intervening in affected sewage and creek systems.
In 1984, a cover of approximately 40 acres, consisting of a high-density polyethylene barrier and clean soil, was installed over the contaminated area. Systems were also created to limit water ingress and prevent it from continuing to contact the buried waste.
Between 1986 and 1987, about 68,000 linear feet of sanitary and drainage lines underwent cleanup work. From 1987 to 1989, approximately 14,000 cubic yards of sediment were removed from the Black and Bergholtz creeks.
EPA states that cleanup actions were concluded in 1999. In September 2004, Love Canal was removed from the federal Superfund program priority list.
Some areas deemed suitable for occupation have been reinhabited. More than 260 previously abandoned houses were restored and sold during the revitalization process.
However, the old landfill did not simply disappear. Containment, collection, and treatment systems continue to be operated, maintained, and monitored, including inspections of the cover and wells used to track groundwater. EPA also conducts periodic reviews to assess the ongoing effectiveness of the protective measures implemented at the site.
