Survey Description


Helicopter and truck-supported sample collection was carried out in the Bella Coola area, British Columbia during the period July 22 to August 13, 2001.  A total of 1180 stream sediment and 1180 stream water samples were collected from 1003 sites.  The average sample site density was 1 site per 12.2 km2 over the 13,345 square kilometre survey area.  Field duplicate samples were collected in each analytical block of twenty samples.  Samples were not collected in Tweedsmuir Park, the Fiordland-Kitlope Recreation area and a previously surveyed area immediately south of the Bella Coola highway.  The data are published in GSC Open File 4414/British Columbia Regional Geochemical Survey RGS 56.

This survey was carried out using National Geochemical Reconnaissance (NGR) protocols.

Sampling Procedure

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 the east quarter of NTS 103A (Laredo Sound), all of 93D (Bella Coola) and the very southwest corner of 93C (Anahim Lake) in west-central British Columbia.  Samples were not collected in Tweedsmuir Park, the Fiordland-Kitlope Recreation area or in a previously surveyed area immediately south of the Bella Coola highway.  It is bounded to the west by Princes Royal Island and Queen Charlotte Sound.
