Chemical Name and Groundwater Remediation Objective
Notations
a The
Equation S17 is used to calculate the Soil Remediation Objective for the Soil
Component of the Groundwater Ingestion Route; this equation requires
calculation of the Target Soil Leachate Concentration (Cw) from
Equation S18: Cw = DF x GWobj.
b Value
listed is the Water Health Based Limit (HBL) for this chemical from Soil
Screening Guidance: User’s Guide, incorporated by reference at Section
742.210. The HBL is equal to the non-zero MCLG (if available); the MCL (if
available); or, for carcinogens, a cancer risk of 1.0E-6, and for
noncarcinogens is equal to a Hazard Quotient of 1.0. NOTE: These GWobj
concentrations are not equal to the Tier 1 Groundwater Remediation Objectives
for the Direct Ingestion of Groundwater Component of the Groundwater Ingestion
Route, listed in Section 742.Appendix B, Table E.
c Value
listed is also the Groundwater Quality Standard for this chemical pursuant to
35 Ill. Adm. Code 620.410 for Class I Groundwater or 35 Ill. Adm. Code 620.420
for Class II Groundwater.
