BC RGS stream sediment and water survey, NTS 92F, southern Vancouver Island and Lower Mainland, British Columbia, 1989.
(requires an Internet connection)
In June to August 1989, a total of 908 sites were sampled for moss-mat sediment, stream sediment and stream water at an average density of 1 site per 10.9 km2. Larger municipalities and provincial parks were excluded from the sampling. Samples were collected by truck, boat or helicopter depending on accessibility. Moss-mat sediments were collected on Vancouver Island; stream sediments were collected on the Lower Mainland. The data are published in British Columbia RGS 25/Geological Survey of Canada Open File 2183.
This survey was carried out using National Geochemical Reconnaissance (NGR) protocols.
Moss-mat sediment samples weighing 1-2 kg were scraped from logs and boulders found within the active stream channel and placed in kraft-paper bags. Unfiltered water samples were collected in 250 ml Nalgene bottles and precautions were taken to exclude suspended solids when possible.
