Microbiologist Scott Fernandez advocates for the future of Portland's public water system based on use of an unfiltered, nontreated Bull Run water source. Addresses the concerns that building costs due to requirements to conform to EPA regulations requiring water treatment and covering of our open air reservoirs. Looks at the additional costs and dangers posed to the public system by adding fluoride to the system as might be required by a May ballot measure. Scott advocates for a permanent waiver as opposed to a temporary variance and explains the difference.
