Niagara Falls, New York, is famous for two things: the waterfalls and one of the worst environmental disasters in U.S. history. Love Canal put this city on the map for all the wrong reasons in the late 1970s, and the chemical contamination legacy hasn’t fully gone away.
Today, roughly 48,000 residents depend on water drawn from the Niagara River — the same river that’s been receiving industrial discharge for over a century. Understanding what’s in that water, and what’s still in the ground beneath the city, matters.
The Love Canal Legacy
Between the 1940s and 1950s, Hooker Chemical (later Occidental Chemical, or OxyChem) dumped approximately 21,000 tons of toxic chemicals into an abandoned canal on the city’s southeast side. The waste included dioxins, benzene, toluene, chloroform, and dozens of other hazardous compounds.
The site was covered over and sold to the Niagara Falls Board of Education for one dollar. A school and homes were built on top of it. By the late 1970s, chemicals were seeping into basements and yards. Over 200 families were relocated. In 1980, President Carter declared a federal emergency — only the second time that had ever happened for an environmental disaster.
Love Canal became a Superfund site and a catalyst for the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) — the law that created the Superfund program itself.
It Didn’t End With Love Canal
Love Canal gets the headlines, but Niagara Falls and the surrounding Niagara County host multiple contamination sites. The EPA lists several active Superfund sites in the area:
- Love Canal — Still under long-term monitoring. Containment systems manage leachate, but the waste remains underground.
- Hyde Park Landfill — Another OxyChem disposal site containing an estimated 80,000 tons of chemical waste, including lindane, mirex, and chlorinated benzenes.
- 102nd Street Landfill — A former chemical disposal area along the Niagara River with documented groundwater contamination.
- Niagara Falls Storage Site — Part of the formerly utilized sites remedial action program (FUSRAP), containing radioactive waste from the Manhattan Project era.
The concentration of chemical and radioactive waste sites in this relatively small area is unusual, even by industrial Northeast standards.
Current Drinking Water Quality
The City of Niagara Falls draws its drinking water from the upper Niagara River, upstream of the falls. The Niagara Falls Water Board treats water at its Michael C. O’Laughlin facility using conventional treatment: coagulation, sedimentation, filtration, and chlorination.
Recent Consumer Confidence Reports show the water meets all EPA primary drinking water standards. However, several contaminants have been detected at measurable levels:
- Haloacetic acids (HAA5) — Disinfection byproducts formed when chlorine reacts with organic matter in the source water. Levels have approached but stayed below the EPA maximum contaminant level of 60 ppb.
- Total trihalomethanes (TTHMs) — Another group of disinfection byproducts, detected at levels that are compliant but higher than ideal.
- Lead — Some older homes with lead service lines or lead solder show elevated lead at the tap. The system has generally stayed below the EPA action level of 15 ppb, but any lead exposure is a concern for children.
The Niagara River itself carries contamination from upstream industrial sources in both the U.S. and Canada. The International Joint Commission has identified the Niagara River as an Area of Concern under the Great Lakes Water Quality Agreement, citing contaminated sediments and ongoing pollutant loading.
PFAS: The Emerging Concern
Per- and polyfluoroalkyl substances (PFAS) have been detected in water systems throughout the Niagara region. The Niagara Falls Air Reserve Station and former industrial facilities used PFAS-containing firefighting foam (AFFF) extensively.
The EPA finalized its first national PFAS drinking water standards in 2024, setting limits of 4 parts per trillion for PFOA and PFOS individually. Water systems nationwide are testing and must comply by 2029. For Niagara Falls, with its military and industrial history, PFAS monitoring is especially relevant.
New York State set its own PFAS limits — 10 ppt for PFOA and PFOS — which took effect before the federal rule. The Niagara Falls Water Board has been conducting PFAS testing as required, and residents should watch future water quality reports closely.
Groundwater Contamination
While the city’s public water supply comes from the Niagara River (surface water), the groundwater beneath Niagara Falls is extensively contaminated. Decades of chemical manufacturing and disposal have left a patchwork of contaminated plumes underground.
Residents on private wells — particularly in surrounding towns in Niagara County — face the highest risk. Groundwater near Superfund sites contains volatile organic compounds (VOCs), heavy metals, and pesticide residues at levels far exceeding safe drinking water standards.
If you’re on a private well in Niagara County, testing isn’t optional. It’s essential.
What Residents Can Do
- Read your annual water quality report. The Niagara Falls Water Board publishes these each year. Look at actual detected contaminant levels, not just whether they’re “in compliance.”
- Test for lead at the tap. If your home was built before 1986, you may have lead service lines or lead solder. Free or low-cost testing programs are often available through the county health department.
- Ask about PFAS results. As testing ramps up under new federal and state rules, request the latest PFAS data from your water provider.
- Consider point-of-use filtration. A certified activated carbon filter can reduce disinfection byproducts and some organic contaminants. For PFAS, look for NSF/ANSI 53 or 58 certified systems — reverse osmosis is particularly effective.
- Private well owners: test annually for VOCs, heavy metals, nitrates, bacteria, and PFAS.
The Bottom Line
Niagara Falls’s public water supply meets current EPA standards, but this city’s contamination history demands more scrutiny than most. Love Canal is contained, not cleaned up. Multiple other waste sites continue to require monitoring. And the emerging PFAS issue adds another layer to an already complex picture.
If you’re concerned about your water quality, a certified water treatment professional can test your water and advise on solutions tailored to your specific situation.
