"*" Indicates that the
ADL is less than or equal to the specified remediation objective.
NA means Not Available; no PQL or
EQL available in USEPA analytical methods.
Chemical Name and Soil
Remediation Objective Notations (2nd, 5th thru 8th
Columns)
a Soil
remediation objectives based on human health criteria only.
b Calculated
values correspond to a target hazard quotient of 1.
c No
toxicity criteria available for this route of exposure.
d Soil
saturation concentration (C[sat]) = the concentration at which the
absorptive limits of the soil particles, the solubility limits of the available
soil moisture, and saturation of soil pore air have been reached. Above the
soil saturation concentration, the assumptions regarding vapor transport to air
and/or dissolved phase transport to groundwater (for chemicals which are liquid
at ambient soil temperatures) have been violated, and alternative modeling
approaches are required.
e Calculated
values correspond to a cancer risk level of 1 in 1,000,000.
g Chemical-specific
properties are such that this route is not of concern at any soil contaminant
concentration.
h 40
CFR 761 contains applicability requirements and methodologies for the
development of PCB remediation objectives. Requests for approval of a Tier 3
evaluation must address the applicability of 40 CFR 761.
i Soil
remediation objective for pH of 6.8. If soil pH is other than 6.8, refer to
Appendix B, Tables C and D in this Part.
j Ingestion
soil remediation objective adjusted by a factor of 0.5 to account for dermal
route.
I Potential
for soil-plant-human exposure.
m The
person conducting the remediation has the option to use: (1) TCLP or SPLP test
results to compare with the remediation objectives listed in this Table; (2)
the total amount of contaminant in the soil sample results to compare with pH
specific remediation objectives listed in Appendix B, Table C or D of this Part
(see Section 742.510); or (3) the appropriate background value listed in
Appendix A, Table G. If the person conducting the remediation wishes to
calculate soil remediation objectives based on background concentrations, this
should be done in accordance with Subpart D of this Part.
n The
Agency reserves the right to evaluate the potential for remaining contaminant
concentrations to pose significant threats to crops, livestock, or wildlife.
o For
agrichemical facilities, remediation objectives for surficial soils which are
based on field application rates may be more appropriate for currently
registered pesticides. Consult the Agency for further information.
p For
agrichemical facilities, soil remediation objectives based on site-specific
background concentrations of Nitrate as N may be more appropriate. Such
determinations shall be conducted in accordance with the procedures set forth
in Subparts D and I of this Part.
q The
TCLP extraction must be done using water at a pH of 7.0.
r Value
based on dietary Reference Dose.
s Value
for Ingestion based on Reference Dose for Mercuric chloride (CAS No.
7487-94-7); value for Inhalation based on Reference Concentration for elemental
Mercury (CAS No. 7439-97-6). Inhalation remediation objective only applies at
sites where elemental mercury is a contaminant of concern.
t For
the ingestion route for arsenic for industrial/commercial, see 742.Appendix A,
Table G.
u Value
based on Reference Dose for Thallium sulfate (CAS No. 7446-18-6).
w Value based on Reference Dose
adjusted for dietary intake.
x For any populated areas as defined in
Section 742.200, Appendix A, Table H may be used.
y Value
based on maintaining fetal blood lead below 10 µg/d1, using the USEPA adults
Blood Lead Model.
