24. Some Illinois Samples: Row Crop Sites

25. Nitrate Isotopes: ISU Research Farm

26. Pharmaceutical and Personal Care Products (PPCPs) in the Environment Tetracycline in Soil Amendments and Soils: ISU Farm *ng/mL ^ng/g

27. Program Objectives: Monitoring Confined Animal Feeding Operations (CAFOS) • Monitor Long-Term Groundwater Quality Near Swine Confinement Facilities • Determine the Occurrence and Concentration of: • Nutrients • Viruses • Antibiotics • Antibiotic Resistance Genes • Evaluate the fate and transport of antibiotics and antibiotic resistance genes in soil and groundwater

28. Tetracycline Detections

29. Chloride Concentrations and tet Gene Frequency Chloride (mg/L) Gene Frequency (%) (2000-2003 N = 95)

30. Determining Soil Cleanup Objectives (SCOs) for IDOA • Derive SCOs for fertilizer NH4-N spills • Protect groundwater quality in Illinois • SCO ≈ amount sorbed plus extent of dilution times a groundwater quality objective • Movement of NH4+ as well as nitrification • 10 mg/L as N yields a default SCO of 38 mg/kg for NH4+ • Experiments showed SCOs correlated with cation exchange capacity (CEC)

31. Proposed Default Soil Cleanup Objectives for Ammonium: Since Promulgated by IDOA
