Mark Sandstrom, Ph.D.



My research is on the development and application of new analytical methods to study the transport, fate and effects of pesticides water quality studies. Analytical instruments used for this work include gas and liquid chromatographs coupled to mass spectrometers, and improvements in these instruments provide opportunities to implement methods that provide more pesticide compounds, lower detection levels, and more efficient sample processing. The methods are implemented in the National Water Quality Laboratory and used for routine analysis by Water Resources Mission Area scientists and National Programs. I also study more efficient ways to collect and process water samples, for example time-integrating samplers for water and sediment.
