NGR stream sediment and water survey, NTS 93K, central British Columbia, 2002
(requires an Internet connection)
Helicopter and truck-supported sample collection was carried out in the Fort Fraser map area, British Columbia during the period July 25 to September 5, 2002. A total of 843 stream sediment and 789 stream water samples were collected from 795 sites. The average sample site density was 1 site per 13.2 km2 over the 10,500 square kilometre survey area. Field duplicate samples were collected in each analytical block of twenty samples. The data are published in GSC Open File 1766/ British Columbia Regional Geochemical Survey RGS 57.
This survey was carried out using National Geochemical Reconnaissance (NGR) protocols.
Sediment samples weighing 1 to 2 kg were obtained from the active stream channel. Samples were primarily fine-grained material mixed with varying amounts of coarse sand, gravel and organic material. Surface water samples were collected in 250 mL bottles and at every fifth site, an additional 60 mL water sample was collected. Suspended solids were excluded where possible.

The geographic extent of the survey is defined by the following polygons:
Covers all of 93K (Fort Fraser) in central British Columbia except the northeast corner (a lake sediment and water survey published in BC Open File 1996-15/GSC OF 3305 and BC Open File 1999-5) and a small area just northwest of the centre of the map sheet on part of the Nechako Plateau where no samples were collected.
