Plomb Forces Kahnawake School to Halt Maple Season

The word plomb has now become a hard stop for the Kahnawake Survival School, which has suspended its maple season after tests found elevated contamination in its maple water. The school, near an industrial park in Kahnawake, made the decision after environmental checks were carried out last month. The concern is not only about the sap itself, but about what it may reveal in a territory already surrounded by pollution.
Tests Trigger Immediate Suspension
Testing by the Kahnawake Environment Protection Office found concentrations of plomb in maple water that were up to eight times higher than the recommendation from Health Canada for drinking water. Because roughly 40 liters of sap are needed to produce one liter of syrup, the contamination would become even more concentrated in the finished product. That means the school’s traditional maple season is not only paused; it is being treated as a health issue.
The school’s students usually harvest maple water in the surrounding forest in spring, a practice that is central to Kanienʼkéha: ka culture. This year, that same water is not being used as a traditional remedy and will not be turned into maple syrup. The decision was made after community concerns grew about the school’s location near industrial activity.
Community Leaders Point to Wider Pollution
Cody Diabo, Grand Chief of the Mohawk Council of Kahnawake, said the findings raise deep concern for the community and the territory. He said the situation leaves people wondering what invisible substances they may be exposed to. His remarks reflect a broader anxiety tied to the school’s setting beside the Sainte-Catherine industrial park in Montérégie.
Stuart Myiow, wolf clan representative on the Kahnawake Traditional Council, also criticized the placement of a secondary school near heavy industry, including a lead recycling operation. He raised the question during a community meeting organized by Kahnawake Land Defenders last week. The school is also near a plant identified as being about 1 kilometer away, and earlier revelations about lead and sulfate releases there did not ease fears.
Education Shifted From Harvesting to Investigation
Sha’teiohserí: io Patton, director of Kahnawake Survival School, said the suspension is a loss, but also an opportunity to teach students about environmental activism and environmental racism. She said the community is surrounded by three busy roads, an industrial park, the seaway, two quarries, and several landfills, all of which add to the pollution burden.
Patton said the school plans to replace the maple-water collection with a talk by a scientist and a student-led sampling exercise so they can test the safety of what they gather. She also said parents have already offered to move classes to a family sugar bush, showing how the community is trying to keep the tradition alive despite the setback. In this case, plomb has become both a warning and a lesson.
What Happens Next
For now, the exact source of the contaminants remains unknown, and officials have not identified where the plomb entered the maple water. The school’s next steps will likely focus on testing, education, and deciding how to continue spring traditions safely. Until then, the maple season at Kahnawake Survival School remains interrupted, with plomb still at the center of the story.
