The tanker that toppled into Lemon Creek on Friday, spilling up to 35,000 litres of jet fuel, has been removed.
Executive Flight Services of Calgary, which owned the tanker, has the lead role in remediation efforts at the site, according to the Regional District of Central Kootenay.
The tanker made a wrong turn onto Lemon Creek forest service road while heading to a fueling station for helicopters tackling the Perry Ridge wildfire.
The RDCK has scaled back its emergency operations centre and lifted its state of local emergency, but residents can still call 1-800-268-7325 for information.
"Although much of the fuel has vaporized and air/water sample levels are within prescribed standards, the Interior Health Authority has a order in place that impacts surface water users south of Lemon Creek within the geographic area covered by the evacuation order," the regional district said in a news release Sunday.
People are advised not to drink surface water, irrigate their crops, or swim in the Slocan River.
"The Ministry of Environment along with other agencies continues to remediate the impacts of the fuel spill and monitor water courses and air quality throughout the geographic evacuation order area," the RDCK added.
"The Regional District of Central Kootenay is very appreciative of the efforts of the many volunteer fire departments and the numerous agencies and individuals who assisted in responding to the incident and subsequent evacuation of residents."
