This study compares an alternate test method (adenosine triphosphate, ATP) with the current method used by MetroVancouver (heterotrophic plant count, HPC) for monitoring bacteriological activity in the water transmission system to support continuous innovation of Metro Vancouver's water services. Includes a review of HPC and ATP studies, analysis of water quality data from Canadian municipalities, and results of preliminary ATP testing for the Greater Vancouver Water District transmission system.
