Unusual results:

Electical conductivity displayed O.r (out of range). Test was repeated with re-calibrated instrument. Same result, O.r was obtained in second test.

Out of range results for dissolved oxygen.

Possible explanation: The unusual results could be due to a variation in the sampling, as on this particular visit the water sample was taken a few meters further up the creek than usual. Overgrowth on the sand bank obstructed access to the usual sampling spot and the sample was taken by going around and behind the bush to collect water a few meters further up the creek and away from the Bay.
