Staff chemists provide chemical analyses for the Water Survey and the University of Illinois in support of research activities. Measurements include metals, nutrients, and other inorganic parameters for projects on groundwater quality, watershed monitoring, well contamination, atmospheric processes, and lake quality. Staff consult with other researchers on their analytical needs and the development of quality assurance plans for laboratory data and analytical procedures as needed.

The laboratory is managed by Daniel Webb, who also  oversees the Public Service Laboratory.  Water Survey researchers should contact Dan to discuss their analytical needs and budgets when writing proposals.
