Chemical spill in Okanagan town?

Evidence of chemical spill

Citizens of a small Okanagan town (Oliver BC) woke to find a chemical spill this morning had coated exposed surfaces in the town. A fine layer of crystalline di-hydrogen oxide in powder form had settled almost everywhere.  (See attached photo).   Brisk winds raised concerns that it would come in contact with the skin of the elderly and infants and possibly even enter the town's water supply.  Should the government be doing something about this?
