Engineering Project – Groundwater Treatment for Elevated Arsenic – Nisqually Commercial Park, Olympia, WA (July 2009-December 2011)

Our client was tasked with installing a water treatment system for drinking water supply at his commercial park with 45 residents based on EPA’s new maximum arsenic concentration of 10 ppb. Creekside’s scope of work involved review of maps, aerial photographs, historical water quality data, and Washington Department of Ecology (DOE) file documents, site visits, collection and analysis of samples from nine wells and one spring located within one mile of the subject property, completion of a treatability study and pilot plant, review of various engineering options for treating the well water, obtaining construction permits, and design and installation of the water treatment system which is currently operating at the site.
