Results* from water samples collected in April are now available from 5/14 (above: bold italics) of the current InFORM sampling locations. While our expectations are that the plume would first appear in samples from the southern outer coast of Vancouver Island, the new data from other regions does not yet have any measureable ¹³⁴Cs, the fingerprint of the Fukushima plume due to its short ~2 year half-life. 

All coastal samples continue to have measureable levels of ¹³⁷Cs (half-life ~30 years), that is present because of atmospheric nuclear weapons testing that happened in the 1950s and 1960s and the 1986 Chernobyl nuclear disaster.

*Note: Results are preliminary and may be slightly adjusted pending results from further chemical analysis.
