100-Year Floodplain in Illinois (2009, August 6)
Map of 100-Year floodplain in Illinois. The 100-year floodplain represents that portion of the topography that would be inundated during a flood event which has a 1% chance of occurrence in any given year. The mapped 100-year floodplain area represents the best available data as of July 2009.

Annual Report to the Illinois Council on Food and Agricultural Research {periodical start}
Annual Reports. The Illinois Council on Food and Agricultural Research (C-FAR) is a statewide partnership organized to support relevant, high-quality research and related outreach programs for Illinois food, agricultural, and related systems. The annual report from the University of Illinois at Urbana-Champaign, Southern Illinois University-Carbondale, Illinois State University and Western Illinois University contains high-lights of research activities conducted on behalf of the Illinois Council on Food and Agricultural Research (C-FAR).
Applicability of Microfiltration for Recycling Semi-Synthetic Metalworking Fluids (2007, December) [RR-111]
This research seeks to investigate the applicability of microfiltration technology by investigating the membrane fouling mechanisms at work in the system. It also aims to reduce fouling through adjustment of operating parameters and the design of a new semi-synthetic MWF that significantly reduces the impact of membrane fouling.

Arsenic Geochemistry and Distribution in the Mahomet Aquifer, Illinois [RR-107]
Groundwater samples were collected from approximately 50 private wells in Tazewell County, an area where arsenic contamination is known from previous sampling, and northwest Champaign County, an area for which very few arsenic data were available. Most of the wells were finished in the Mahomet Aquifer, with roughly equal numbers of wells near the bottom, middle, and upper part of the aquifer. A few of the wells were finished in the Glasford Aquifer, which lies above the Mahomet. A reliable, robust method for arsenic speciation was developed based on separation of species by HPLC and ICP-MS detection. The samples were analyzed for total arsenic, arsenic species, metals, anions, alkalinity, ammonium, and total organic carbon. Samples of raw groundwater and finished potable water were collected from 11 municipal water treatment plants that withdraw water from the Mahomet Aquifer.
