In July 1991, a reconnaissance geochemical survey was conducted in the Howe Sound drainage basin, British Columbia. Several sample types were collected: surface waters from the mouths of creeks and rivers draining the east side of the Sound, and a few at depth within some bays; near-shore bottom sediments from several bays; and seaweed (Fucus gardneri, common rockweed) from rocks along shorelines within the Sound. In addition, creek waters, acid mine waters and mineral precipitates were also collected from the Britannia mine site for detailed study. Two water samples were collected at each of 23 sites: one 250 mL volume for cation determination and one 125 mL volume for anion determination and pH. Twenty of the 44 water samples collected focused on the drainage in the area of the Britannia copper mine. Thirteen sediment samples of 100-200 g were collected by a petite Ponar grab sampler from a 15 x 15 cm area. Seaweed samples were collected at intervals of approximately 5 km during periods of medium to low tides. About 100-200 g of seaweed were plucked from the rocks at each of the 36 sites selected within the 300 km2 study area. This report on this study can be found in Geological Survey of Canada Current Research Part A, Paper 92-1A.

The geographic extent of the survey is defined by the following polygons:
Covers part of NTS 92G, Howe Sound area in southwestern British Columbia. It is bounded to the south by the Strait of Georgia and extends to Squamish in the north and to Port Mellon in the west.
