2010 GSA Denver Annual Meeting (31 October –3 November 2010)
420 Thursday, 4 November 2010
10:00 AM-12:00 PM, Colorado Convention Center: Lobby E

A 2-hour walking tour of the US Geological Survey’s National Water Quality Laboratory

Primary Leader: Gary L. Cottrell
Leader(s): Donna Damrau
Field Trip Description: This tour of the U.S. Geological Survey’s National Water Quality Laboratory (NWQL), located on the Denver Federal Center will include brief discussions on sample preparation and analysis, as well as an overview of the physical facility. The USGS gathers data for determining the location, amount, availability, and quality of ground and surface water throughout the United States and its territories. About 75%–80% of the water-quality samples used in this effort are analyzed by the NWQL. The NWQL determines organic and inorganic constituents in samples of ground and surface water, river and lake sediment, aquatic plant and animal material, and in precipitation samples. The NWQL receives about 30,000 samples every year for chemical analysis, generating well over 1 million individual results. The NWQL has the capability to provide a wide range of analytical services from routine trace metals analyses to trace and ultra-trace organic analyses that often require advanced methods of sample preparation and analysis. For additional information about this world-class laboratory, go to http://nwql.usgs.gov/Public/nwql.shtml. The tour at the NWQL (bldg 95, Denver Federal Center) will start at 10 a.m. and will run ~2 hours. This is a walking tour, and we will visit laboratory areas, so it is important that visitors do not wear sandals or shorts. Safety glasses will be provided.
Field Trip will span: 1 day
Sponsor(s): USGS National Water Quality Laboratory
