Thank you very much for the question. I appreciate it.
Indeed, TCE is a well-studied chemical solvent that can cause cancer. As you may know, it's been used for many decades, primarily for automotive metal industries, degreasing and cleaning metal parts. Through the Canadian Environment Protection Act, there were regulations put in place to reduce exposure to Canadians and the environment. It is noted that people living in close proximity to contaminated sites may be exposed to TCE in drinking water as well as through air, water and food.
