Nitrate in the Mississippi River

The data on this page are generated by an in situ nitrite/nitrate analyzer located in the Mississippi River behind the Audubon Zoo in New Orleans, Louisiana. The NAS-2E is manufactured by WS EnviroTech (http://www.n-virotech.com/). We currently are generating a data point every hour with a blank and check standard also analyzed every hour. We rotate the meters every two weeks to allow us to download data, clean the instrument and refill the reagents. For more information, please contact Dr. Rodney T. Powell (rpowell@lumcon.edu).
