BC RCMP say the operators of a drug lab near Bridesville, east of Osoyoos, dumped solvents and other hazardous materials into the soil, possibly contaminating the local water table.
Interior Health says while the risk of exposure is low - they're contacting about 25 properties between Bridesville and Rock Creek to stop using their water until more tests can be done.
I-H says there's is no risk for anyone drawing water from aquifers or deep wells - or to those downstream along the Kettle River.
They say the communities of Bridesville, Rock Creek, and Midway are not impacted.
