HERBICIDES IN SOURCE-WATER AQUIFERS TAPPED BY PUBLIC-SUPPLY WELLS IN ILLINOIS

During October 2001-September 2002, the U.S. Geological Survey (USGS), in cooperation with the Illinois Environmental Protection Agency (IEPA), conducted a study of herbicides and herbicide transformation products (also referred to as degradates or metabolites) in source-water aquifers used for public-water supply. One-hundred seventeen randomly selected public-supply wells distributed statewide were sampled. The selected wells represent the various unconsolidated (glacial, alluvial) and bedrock (carbonate, sandstone) aquifers of the State, as well as various aquifer depths, well depths, and near-well (within 2 miles) land uses. Interpretive results of the ground-water study are presented in Mills and McMillan (2004).

Water samples were collected using purge criteria based on stabilization of field-determined water-quality characteristics (specific conductance, pH, temperature and oxidation-reduction potential) and minimum well-casing volumes to ensure samples were representative of the ground-water quality. Field characteristics were measured by personnel from the Illinois Environmental Protection Agency. Water samples were collected before water treatment (chlorination and fluorodation, for example), and were filtered through a 0.7 micron baked glass-fiber filter using a stainless steel and Teflon filtering device. All samples were chilled immediately to 4 degrees Celsius for handling and shipment to the USGS Organic Geochemistry Research Laboratory in Lawrence, Kans. The laboratory received all samples within 1-3 days of sample collection. Using solid-phase extraction techniques, parent herbicides, the atrazine transformation products deethylatrazine and deisopropylatrazine, and the cyanazine transformation product cyanazine-amide were analyzed by gas chromatography/mass spectrometry (GC/MS) (Zimmerman and Thurman, 1999; Kish and others, 2000). Chloroacetanilide herbicide transformation products (ethanesulfonic (ESA),oxanilic acid (OA), and sulfynil acetic acid (SAA) compounds) were analyzed by high-performance liquid chromatography/mass spectrometry (LC/MS) (Zimmerman and others, 2000; Lee and others, 2001). Glyphosate was analyzed by liquid chromatography (Lee and others, 2002).
