BC RGS stream sediment and water survey, NTS 92N, southwest British Columbia, 1991.
(requires an Internet connection)
Helicopter and truck-supported sample collection was carried out during the summer of 1991 in the Mount Waddington map area. A total of 868 stream sediment and 807 stream water samples were collected from 820 sites. The average sample site density was 1 site per 18 km2 over the 15,500 square kilometre survey area. Field duplicate samples were collected in each analytical block of twenty samples. The survey also included the collection of nine sediment and water samples in the southern tip of Tweedsmuir Provincial Park. The data are published in British Columbia Regional Geochemical Survey RGS 34.
This survey was carried out using National Geochemical Reconnaissance (NGR) protocols.
In general, sample sites were restricted to primary and secondary drainage basins having catchment areas of less than 10 square kilometres. Contaminated or poor-quality sample sites were avoided by choosing an alternate stream or by sampling a minimum of 60 metres upstream from the identified problem. Fine grained stream sediments (<1 mm) weighing 1-2 kg were obtained from the active stream channel. Unfiltered water samples were collected in 250 mL bottles and precautions were taken to exclude suspended solids where possible.
