Description
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.
