Citing results of soil sampling, Enbridge Inc. said the dust that settled around the site of a natural gas transmission pipeline rupture in British Columbia does not pose any health risks.

Enbridge did not detect hydrocarbons during the sampling, showing that the mineral and metal composition of the samples is "well below" provincial and federal standards for urban and residential areas, according to an Oct. 15 update.

The company also said in an earlier update that "soil invertebrates and vegetation root networks are still active and viable" in the area of the rupture. Based on the findings, the site is expected to recover quickly, Enbridge said.

Enbridge is building a temporary access road to the site of the rupture to facilitate repair work, which is expected to begin later in the week. The company does not yet have a timeline for the completion of the repairs.

The Oct. 9 rupture near Prince George, British Columbia, caused an evacuation of 100 members of the Lheidli T'enneh First Nation and a gas supply shortage in areas of British Columbia and the U.S. Pacific Northwest.
