Notes: a Chemical Abstract Service (CAS) b USEPA "Methods for the Determination of Organic Compounds in Drinking Water" Supplement III of 1995 c Groundwater Quality Standards for Class I: Potable Resource Groundwater (35 Ill. Adm. Code 620.410) d Groundwater Quality Standards for Class II: General Resource Groundwater (35 Ill. Adm. Code 620.420) e Tiered Approach to Corrective Action Objectives (TACO): Values Used to Calculate the Tier I Soil Remediation Objectives for the Migration to Groundwater Portion of the Groundwater Ingestion Route (35 Ill. Adm. Code 742.Appendix B:Table F) f Human Threshold Toxicant Advisory Concentration (HTTAC) from "Procedures for Determining Human Threshold Toxicant Advisory Concentration for Class I: Potable Resource Groundwater" (35 Ill. Adm. Code 620.Appendix A) using values from Integrated Risk Information System (IRIS), USEPA g Class II GWobj values based on Class I GWobj values times 5 h USEPA "Test Methods for Evaluating Solid Wastes, Physical/Chemical Methods (SW-846)", July 1992 i HTTAC using values from Health Effects Assessment Summary Tables (HEAST), 1997, USEPA j Value from the Acetochlor Registration Agreement monitoring program, http://www.epa.gov/oppefed1/aceto/index.htm k MCL value from Drinking Water Standards and Health Advisories (Summer 2000, EPA 822-B-00-001) l HTTAC using RfD value from Drinking Water Standards and Health Advisories (Summer 2000, EPA 822-B-00-001) m HTTAC using RfD value from Risk Assessment Information System (RAIS), http://risk.lsd.ornl.gov/rap_hp.shtml n In order to provide environmentally conservative default SCOs that take into account the potential for long-term nitrification, one-third of the USEPA's Lifetime Health Advisory Level for ammonia in drinking water (30 mg/L) is used as basis for the groundwater cleanup objectives for Class I and Class II groundwater (U.S. Environmental Protection Agency, 2004, 2004 Edition of the Drinking Water Standards and Health Advisories, Office of Water, Washington, D.C., EPA 822-R-04-005). Although the Lifetime Health Advisory Level was established for ammonia, most of the dissolved ammonia occurs as ammonium within the pH range (5.6-9.0) of Illinois groundwater.
