Hanson Harbor Homeowners Association (HHHOA) and the project sponsor Varela and Associated Inc. have contacted Gonzaga University (GU) asking to help regulate arsenic in Hanson Harbor’s groundwater system.  Due to the changes in policy at the Environmental Protection Agency (EPA) and the Washington State Department of Health (DOH), arsenic concentrations in drinking water must be reduced to 10 ppb by June 30, 2013.  Hanson Harbor currently has arsenic concentrations of approximately 16-17 ppb in their water.  The budget for this remediation project is about $1.3 million and the project site is located north of Wilbur, Washington, along the Columbia River. Our design team researched and evaluated several arsenic removal techniques and created a report to identify the best arsenic treatment option for Hanson Harbor to achieve compliance with the EPA regulations.
