A GN inspector noted smelling fuel on October 10. Was this related to the current issue?

While they sound similar, the observations reported in the media from a GN Inspector are unrelated to petroleum hydrocarbon issue. These were observations by a GN Public Health officer who was onsite on October 8. He visited the water treatment plant for a general overview as he was unfamiliar with the plant and took some tests. While he was on site he noted a smell of diesel. City staff had reported to him that there was a fuel leak on the day tank - which had been isolated and a boiler mechanic was working on the site most of the day. This would contribute to the odour he reported observing. The repairs were completed on October 12 and the diesel smell dissipated at that point.
