Recent research has shown that thousands of oil spill incidents witnessed in the Great Lakes region over a full decade suffer from a severe shortage and absence of detailed data regarding the actual quantities spilled into the water. The study, published in the Journal of Great Lakes Research, found that thousands of spills of varying sizes were recorded between 2015 and 2024, based on relevant government reports and data.
The study was conducted by a research team from Lake Superior State University, aiming to provide a comprehensive and documented picture of reported oil spills in the region over ten years. Celia Hovell, a co-researcher in the study, said that this review provides a comprehensive view of the reality of recorded oil spills, pointing out that focus is often placed on major incidents due to their widespread ramifications, while smaller incidents recur more frequently and their environmental impacts remain insufficiently studied.
The data indicated that about 3,600 spill incidents occurred in U.S. waters, while approximately 2,800 other incidents were recorded on the Canadian side. The majority of incidents in U.S. territory were concentrated around the shipping sector, while Canadian incidents were associated with industrial facilities, sites, and warehouses. The results revealed that only a small percentage of incidents on U.S. territory included detailed reports on the amounts of spilled oil, while quantity data for Canadian spills were absent until 2023.
The researchers emphasized that adopting a more comprehensive and standardized approach to collecting data related to these incidents will contribute to providing more accurate insights into environmental concerns and enhance future risk assessment in the Great Lakes system, calling for the necessity of paying attention to the potential impacts of recurrent, smaller-scale spills.
