Analytical Sample Bundle Metadata
Type: lab data
Download analytical data for this bundle in one of three formats, depending on the desired convention for treating values below the lower detection limit:
NGR lake water analysis, Labrador 1978 survey, NTS 13N, Uranium by fission track, fluorine by ion selective electrode and pH by combination glass-calomel electrode, Barringer Magenta, Toronto.
These analytical data are published in GSC OF 558.
Samples 13N 781436 to 13N 781508 all appear to have bogus water analyses. The F data are almost all below detection. One sample is at the detection limit of 20 ppm. The pH data are all very close to pH 7. The U data are somewhat variable, but all low, < 0.150 ppb. Some of these samples were collected on Aug 21st. There was then a gap in collection until Aug 27th, when the final samples for the survey were collected. 13N 781508 was the last sample site to be visited.
It is speculated that:
the field crew ran out of water bottles during Aug 21st
- sample collection was halted, pending delivery of additional bottles
no additional bottles were forthcoming, so sample collection resumed on Aug 27th, with no water being collected
- bogus water samples were created at a later date, possibly using ordinary tap water
