The Woodstove Exchange Study

Welcome to WEST and WEST II the Follow-Up

WEST, The Wood Stove Exchange Study

is a series of linked projects to assess the impacts of a stove exchange program in the Bulkley Valley Lakes District (BVLD) of BC on community air quality and to investigate the potential improvements in health arising from the change to certified wood stoves.

WEST II is the Follow-up to WEST


August 2013 - Sampling for WEST II is complete! We wish to thank all participants for their continued support.

The next few months will be spent doing preliminary analysis, and collating and checking the data before we get to the full analysis. Once all this is done, we'll send you result letters. Your result letters will contain information on your health tests and the air quality inside and outside of your home. We'll also be able to let you know about the air quality in the Bulkley Valley because, in addition to the air sampling at your homes, we have been sampling the air in the Bulkley Valley since 2007.

March 2013 - Sampling for WEST II is well underway!

We hope to retest all participants before the end of winter. If we've not been in contact with you, and you'd like to be included, please contact us.

January 2013 - Sampling for WEST II is starting!

If you took part in WEST and we've not been in contact with you yet, please send us an email or give us a call. We hope to retest all WEST participants in the next few months.

The sampling time is shorter [only 1 week] and there are fewer physiologic tests.

June 2012 - WEST II coming to the BVLD in winter 2012/13
