Washington Hydrogeology Symposium 2007

The 6th Washington Hydrogeology Symposium was held May 1-3, 2007 in Tacoma, Washington. The Symposium has been in existence since 1995 and provides a unique opportunity to connect with professional hydrogeologists, geologists, and hydrologists from throughout the Pacific Northwest. Additional information can be found on the Symposium website http://www.ecy.wa.gov/events/hg/. This year, over 85 papers were presented with a significant number focused on the Hanford Site. Selected presentations are listed below.
