Overview

These are Indiana’s Published Level Table 1 soil direct-contact standards for semi-volatile organic compounds (SVOCs) and polycyclic aromatic hydrocarbons (PAHs), from the IDEM Remediation Closure Guide (WASTE-0046-R2), effective March 28, 2025. IDEM renamed these values from “Screening Levels” to “Published Levels” in the 2022 R2 update.

Risk basis: Indiana’s published levels are derived at a 1E-05 cancer risk (1 in 100,000) and a hazard quotient (HQ) of 1.0. This is 10 times less conservative than EPA’s default 1E-06 risk level. For carcinogens such as benzo(a)pyrene and many PAHs, Indiana’s values are approximately 10 times higher (less protective) than default EPA Regional Screening Levels.

Qualifier key:

C = Carcinogenic - value is cancer risk-based
N = Noncarcinogenic - value is hazard quotient-based
S = Soil saturation cap
L = 100,000 mg/kg cap
D = Detection limit-based
M = Based on the MCL

Blank cells indicate no published level for that chemical and pathway - not a level of zero.

Practical Notes

PAH carcinogenicity: PAHs are evaluated as a group in most site assessments using benzo(a)pyrene (BaP) as the index compound. IDEM uses toxicity equivalency factors (TEFs) to express PAH risk in BaP equivalents. Check the IDEM Remediation Closure Guide for the current TEF table and calculation method.

Benzo(a)pyrene is typically the most restrictive PAH due to its carcinogenicity. At sites with asphalt, coal tar, or petroleum impacts, benzo(a)pyrene concentrations in soil often exceed published levels even when other PAHs do not.

Phthalates (particularly bis(2-ethylhexyl)phthalate, or DEHP) are common laboratory interferences at high concentrations. If you see elevated phthalates in your results, verify with the laboratory that the detections are not from sample handling equipment before comparing to published levels.

PCBs in this table are individual Aroclor formulations. Indiana follows standard EPA practice for PCB risk assessment. See the Indiana Soil - Pesticides and PCBs page for the complete PCB and pesticide published levels.

Comparing to Ohio: Ohio’s VAP soil standards (OAC 3745-300) use a 1E-06 cancer risk basis. For carcinogenic SVOCs and PAHs, Ohio standards will generally be approximately 10 times lower (more protective) than Indiana’s 1E-05 levels.
