  • Aquifer Adventure -  a Piratey Sucess!

    On Saturday, September 13th over 500 pirates of all ages joined the Portland Water Bureau and the Columbia Slough Watershed Council for an event like no other, a pirate-themed groundwater education festival. Now in its twelfth year, Aquifer Adventure teaches families about our underground treasure - not gold, but groundwater, a precious resource that flows below our feet!

    The event featured a groundwater obstacle course, water conservation activities, information on green household cleaners, edible aquifers made from ice cream, canoe rides on the Columbia Slough and more. Attendees also had the chance to explore a drinking water well site and learn how a real aquifer works from Portland Water Bureau experts.

    What makes groundwater so important?  Groundwater from the Columbia South Shore Well Field is a secondary source of drinking water for Portland and is a critical component of the region’s drinking water system. Groundwater is used to help meet higher summer water demands and to provide water during emergencies or when Portland’s primary drinking water source, the Bull Run watershed, is not available. Having a back-up water supply source also helps the City avoid having to build and operate an expensive water filtration plant for the Bull Run source.
