Brook Sanctuary have had their our independent water sample test results in…
Water samples were collected from the Brook Stream, before the operation and 14, 23, & 47 hours after the operation by the Cawthron Institute. Analysis was carried out by Landcare Research‘s toxicology lab in Christchurch.
All samples have come back with no detectable levels of brodifacoum in the water (that’s less than 0.02 parts per billion).
This is what we expected, Sanctuary Mountain Maungatautari also had undetectable brodifacoum results from similar water testing on 40 streams running out of the fenced sanctuary after their pest removal operation.
