Groundwater Quality Research: INRS Equipment Resources
• Drilling rigs and trained personnel (ISGS)• Field equipment
– Pumps– Multi-sondes (T, pH, ORP, SpC, DO, etc.)– Miscellaneous sampling equipment– Water level measurement devices
Groundwater Quality Research: INRS Analytical Laboratories
• ISWS Public Service Laboratory (PSL)– Anions (ion chromatography); Metals (ICP-AES
and AA); Alkalinity (titration); TKN, NH4-N, NO2-N, P (colorimetry); Organic Carbon (combustion); TDS
– Free analysis for domestic well owners• ISGS Isotopic Geochemistry lab
– Stable isotopes (δD, δ18O, δ13C; sample prep for δ34S)

Groundwater Quality Research: INRS Analytical Laboratories (cont.)
• ISTC analytical laboratories– Metals, including speciation and Hg (ICP-MS, AA)– Organic compounds, such as PAHs, VOCs,
pesticides, etc. (HPLC and GCMS systems)– other
Groundwater Quality Research: INRS Data Resources
• Databases (ISWS and ISGS)– Groundwater quality (domestic and public supply)– Well locations and logs– Water levels, aquifer properties, etc.

Tetracycline in Soil Amendments and Soils: ISU Farm
Program Objectives:• 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

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