Protesters have staged another demonstration at the gates of a southern Vancouver Island company that accepts contaminated soil from elsewhere in the province.

Activist Chad Henderson said a community march was planned this morning near the South Island Aggregates facility in Shawnigan Lake.

Opponents fear contaminants from soil trucked to the site will leach into the waters of Shawnigan Lake, which is an important source of drinking water.

Henderson says about 50 protesters set up a blockade yesterday morning at Duke Point south of Nanaimo, disrupting the unloading of contaminated soil destined for South Island Aggregates, and also demonstrating against logging of old growth timber in the Walbran Valley.
