Complaints of a fuel-like smell coming from the water in this far-north Canadian city prompted do-not-consume orders in October 2021 and January 2022, limiting residents’ access to potable water and its hospital’s ability to sterilize equipment. A team of experts flown in from across Canada identified the sources of the petroleum hydrocarbon contamination and its path into the systems. Sending samples off to labs for testing was slow and costly due to the remote location and harsh winter, so the team worked with a local vendor to adapt existing technology to detect any contamination in real time along different points of the treatment process.
