National Water-Quality Assessment Program (NAWQA) -- Nevada Basin and Range Study Unit
We have continued to participate in a topical study on the Transport of Anthropogenic and Natural Contaminants (TANC) in ground water in the Spanish Springs and Carson City area. We have begun to analyze data collected from public water supply wells and USGS data that is less than 5 years old. Write up of the results will begin this quarter. The TANC study involves using existing data collected by the cities for public supply wells and using this information to determine pathways of contaminants.
We will be finishing the carbonate aquifer sampling northeast of Las Vegas in July. Sampling has progressed well and we anticipate finishing this sampling by the end of July.
The Major Aquifer Study in the Reno/Carson City area that was to begin sampling in January 2003 was postponed until April 2003. This was done because many of the Reno water supply wells will be shut down during January and Truckee River water would be artificially recharged to these wells at this time. Therefore it was decided to avoid sampling at this time. Because of these delays in sampling we are still waiting to sample some of the Reno municipal supply wells. We expect to have this sampling completed in July.
Plans for July – September 2003
Our main focus for July to September 2003 will be to: 1) continue the trend site data collection, 2) Finish sampling the 30 wells for a Major Aquifer Study in the Reno/Carson City areas, 3) Finish planning of the Carbonate Aquifer Major Aquifer Study and start the sampling in June, 4) Place SPMDs in the Tahoe Basin and Truckee River sampling sites in August, 5) Continue sampling water in the Truckee River just upstream of the Chalk Bluff water supply intake as part of a surface water Source Water Assessment study, 6) continue working on the Topical Team (TANC) project, and 7) conduct single and multiple reach ecological sampling on the Truckee and Carson rivers.
The next quarterly update will be posted in October 2003. Comments and suggestions are welcome. Please send your comments to Michael Rosen, NVBR project chief (firstname.lastname@example.org)
