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)

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.
Notes
State regulations are updated quarterly; we currently have two versions available. Below is a comparison between our most recent version and the prior quarterly release. More comparison features will be added as we have more versions to compare.
