Notes:
1 - Applies to the individual results for PFOA and PFOS, as well as the sum of PFOA + PFOS
2 - Regional screening level as presented in the USEPA RSL summary table (TR=1E-06, HQ=1) Novemeber 2014 - May 2022. RSL users screening sites with multiple contaiminants should consult the USEPA (2020) RSL User's Guide and USEPA (1989) Risk Assessment Guidance. Potassium salts of PFBS and PFOS have values identical to PFBS and PFOS.
3 - Interim screening level for groundwater at sites contaiminated with PFOS and PFOA, based on target hazard quotient of 0.1
Notes:
1 - Regional screening level as presented in the USEPA RSL summary table (TR=1E-06, HQ=1) Novemeber 2014 - May 2022. RSL users screening sites with multiple contaiminants should consult the USEPA (2020) RSL User's Guide and USEPA (1989) Risk Assessment Guidance. Potassium salts of PFBS and PFOS have values identical to PFBS and PFOS.
Notes:
1 - Nebraska voluntary cleanup program groundwater and soil remediation goals
Notes:
1 - Levels of public health significance for PFOS and PFOA based on protection of surface waters used for public water supplies for PFOA and protection of human health through fish consumption for PFOS. For PFOA, non-drinking water value that is protective of children's incidental ingestion during surafce water recreation is 0.095 ug/L.
2 - Applies to the individual results for PFOA and PFOS, as well as the sum of PFOA + PFOS
Notes:
1 - Applies to the individual results for PFOA and PFOS, as well as the sum of PFOA + PFOS
2 - Applies to individual or sum of 6 PFAS (PFOS, PFOA, PFHxS, PFNA, PFHpA, PFDA)
Notes:
1 - Ohio applies the EPA HA of 70 ppt to PFOA and PFOS individually or the sum of the two

Notes:
1 - Applies to the individual results for PFOA, PFOS, PFDA, PFHpA, PFNA, and PFHxS as well as the sum of concentrations of these 6 PFAS
2 - Applies to sum of PFOA, PFOS, PFNA, PFHxS
Notes:
1 - Applies to the individual results for PFOA and PFOS, as well as the sum of PFOA + PFOS
2 - Pennsylvania MSCs are reported in the table for aquifers used for residential purposes with a total dissolved solid (TDS) value less than or equal to 2500 mg/L. If it exceeds, the values are multiplied by a factor of 100.
Notes:

Notes:
1 - PFOA and PFOS MCLs were first proposed by NJDEP in 2017 and 2018 and both were adopted in 2020. PFNA MCL was proposed in 2015 and adopted in 2018.
2 - ISGWQC are enforceable standards published by NJDEP by posting on interim groundwater quality standards table
Notes:
1 - Applies to the individual results for PFOA and PFOS, as well as the sum of PFOA + PFOS
Notes:
1 - The 2018 Colorado site-specific groundwater quality standard was adopted to provide a cleanup goal for the contaiminated aquifier in El Paso county only for PFOA + PFOS combined
2 - Criterian applies to individual or combined concentrations of the following: PFOA; PFOS; adjusted value of NEtFOSAA, NMeFOSAA, and PFOSA/FOSA, and PFNA
Notes:
1 - Only human health-based EALs are present here
Notes:
1 - Only human health-based EALs are present here
Notes:
1 - Applies to the sum of PFHxS, PFHpA, PFNA, PFOS, and PFOA
Notes:
1 - Vermont PFAS criteria are for the individual compounds or the sum of PFHxS, PFHpA, PFNA, PFOS, and PFOA
Notes:
1 - New York state guidance values for PFOA and PFOS in soil. Unrestricted values are most stringet of risk-based values.
Notes:
1 - Applies individually and to the sum of PFOS, PFOA, PFHxS
Notes:
1 - HBVs are not promulgated values, but are final values that are in use for guidance purposes by MDH and its partner agencies. Short-term HRL and HBV values are available, but currently equal to subchronic values.
Notes:
1 - Applies only to surface water used as a source of drinking water
Notes:
1 - Applies to the individual results for PFOA, PFOS, PFDA, PFHpA, PFNA, and PFHxS as well as the sum of concentrations of these 6 PFAS
2 - Applies to individual or sum of 6 PFAS (PFOS, PFOA, PFHxS, PFNA, PFHpA, PFDA)
Notes:
1 - Massachussets criteria for S-1 soils including sensitive land uses
Notes:
1 - Applies to the sum of PFHxS, PFHpA, PFNA, PFOS, and PFOA
2- Applies individually and in sum to 6 PFAS in drinking water: PFOA, PFOS, PFHxS, PFNA, PFHpA, PFDA
Notes:
