FREDERICTON, New Brunswick — Provincial authorities have identified a Fredericton-based company as responsible for a chemical spill that spread across a major highway corridor last week, as environmental officials continue investigating the incident and assessing potential impacts on the surrounding environment.
The New Brunswick Department of Environment and Local Government confirmed that XL Plating and Machining, a Fredericton manufacturing firm, has been identified as the party responsible for the spill, which occurred on the evening of March 4.
The incident released approximately 900 litres of industrial chemicals, contaminating a stretch of roadway spanning roughly 14 kilometres. The affected area includes sections of the Vanier Highway and the Trans-Canada Highwaybetween Fredericton and Oromocto, as well as Vanier Industrial Drive.
Officials say the investigation is still ongoing, and enforcement actions — including potential fines or charges — will be determined once the review is complete.
Despite the scale of the spill, provincial authorities have reassured residents that Fredericton’s municipal drinking water system has not been affected, and nearby private wells are also not expected to face contamination.
Cleanup crews quickly moved in after the spill was reported, removing much of the material from the road surface. However, environmental specialists remain on site to evaluate potential effects on nearby soil, drainage areas, and surrounding ecosystems.
New Brunswick’s Local Government Minister Aaron Kennedy said officials understand the concerns raised by residents and commuters who travelled through the affected area.
“The initial phase of the cleanup involved removing the bulk of the material from the roadway,” Kennedy said. “An environmental consultant is continuing work to assess and remediate any impacts on the surrounding environment.”
The spill was formally reported to the Department of Environment and Local Government on March 5. Environmental samples taken shortly afterward confirmed the presence of several chemical compounds, including sodium carbonate, sodium hydroxide, and hexavalent chromium, a substance known for its industrial use and potential health risks under prolonged exposure.
According to health officials, the presence of hexavalent chromium initially raised concerns due to its association with increased cancer risks in cases of long-term exposure. However, authorities say the likelihood of significant exposure in this case appears low.
Dr. Rita Gad, the region’s medical officer of health, explained that the chemical was dispersed over a wide stretch of highway, reducing the chance of harmful exposure levels.
“While long-term exposure to this substance can increase certain cancer risks, brief or one-time contact generally does not,” Gad said, noting that samples collected shortly after the incident showed higher concentrations in areas where the spill appeared most visible.
Environmental testing also detected petroleum hydrocarbons in a soil sample taken from the roadside shoulder. Officials say the presence of these compounds is typical in roadside environments due to asphalt fragments and vehicle residue and does not currently raise additional environmental concerns.
As part of the remediation process, crews removed contaminated soil and water collected from roadside ditches and transported the material for safe disposal.
Provincial officials say further environmental monitoring will continue in the coming weeks. A long-term sampling plan is being developed to test soil and drinking water in the affected region to ensure no delayed impacts emerge.
“We understand there are many questions and still some unknowns,” Kennedy said. “If ongoing monitoring identifies information that changes our understanding of the health risk, the public will be informed.”
Authorities are also asking motorists who travelled through the affected area between March 4 and the afternoon of March 6 to come forward if they believe their vehicles may have been exposed to chemical residue.
The environmental response firm EFI Global has established a 24-hour emergency hotline to assist residents and vehicle owners who may have been affected. Property inspections are also underway for locations where vehicles potentially carried chemical residue into garages or private driveways.
Under New Brunswick’s environmental legislation — including the Clean Air Act, Clean Water Act, and Clean Environment Act — penalties for environmental violations can vary widely. Individuals may face fines ranging from $500 to $50,000, while companies can be fined between $1,000 and $1 million, depending on the severity and circumstances of the violation.
For now, officials say the priority remains environmental remediation and ensuring the safety of residents as investigators work to determine how the spill occurred and whether regulatory breaches took place.
