Blueberry Farm Expansion Near Lac-Saint-Jean Raises Water Contamination Concerns
Residents near Dolbeau-Mistassini, Quebec, are expressing concerns over a new blueberry farm development, fearing potential contamination of their drinking water. The land, previously forested, was recently sold and cleared for blueberry production, prompting worries about pesticide runoff into the local aquifer, which supplies roughly forty homes.
Local Concerns and Environmental Impact
Yves Bonneau, a local resident, stated that the area’s residents are increasingly aware of the agricultural land surrounding their properties. Dany Hébert, another resident, noted the alarming rate of deforestation and its potential impact on the area’s recreational tourism. Beyond water contamination, residents are also concerned about the destruction of wetland habitats and the displacement of wildlife.
Official Response and Regulations
Jean Morency, prefect of the Maria-Chapdelaine MRC, acknowledged the residents’ concerns but emphasized the economic importance of the blueberry industry to the region. He stated that the land is zoned for agricultural use, allowing producers to cultivate their land while adhering to environmental regulations. Dolbeau-Mistassini Mayor Rémi Rousseau assured residents that the city would ensure all regulations are followed.
The city recently communicated to residents that while cottage development is valued, agricultural activities remain a priority. To foster better understanding, Jean Morency proposed reactivating a local advisory table to facilitate communication between all stakeholders.
Developer Efforts and Agricultural Practices
The new blueberry farm is being developed by Dany Gaudreault, Pierre-Luc Villeneuve, and Rémi Mathieu. They have sold a portion of the land to promote good neighborly relations and are maintaining a wider riparian buffer zone – twenty metres – than the standard three metres required in agriculture. They state they are adhering to all regulations.
Pierre-Olivier Martel, an agronomist with the Quebec Ministry of Agriculture, Fisheries and Food (MAPAQ), explained that blueberry production generally requires fewer pesticides and fertilizers compared to crops like potatoes, corn, or other large-scale agriculture. However, the herbicide hexazinone, used in blueberry farming, is soluble in water and slow to degrade, raising concerns about potential groundwater contamination.
Water sampling conducted between 2002 and 2009 detected hexazinone levels of 0.3 micrograms per liter, close to the detection limit, while the permissible limit is 400 micrograms per liter. Similar levels were found in 2022 samples. MAPAQ is currently working on developing alternative, lower-risk herbicides.
