Notes: nc: Residential soil RSL, based on non-cancer hazard quotient of 1. c: Residential soil RSL, based on excess individual lifetime cancer risk of 1E-06. NA: Not available ND: The analyte was not detected, but a reporting limit was not provided. U: The analyte was not detected above the reporting limit. UJ: The analyte was not detected above the estimated reporting limit. J: The analyte was positively identified, but the reported concentration is an estimated value.

Bold: The analyte was detected above the reporting limit. Blue font: The reporting limit was greater than the level of concern. R: The laboratory control sample had an unacceptable response, indicating that it was not possible to obtain valid results for this analyte. c c c c c c c c c c c c nc nc nc nc nc nc nc nc nc nc nc nc1,2,3,4,6,7,8-HpCDD(Heptadioxin)1,2,3,4,6,7,8,9-OCDD(Octadioxin)2,3,7,8-TCDF(Tetrachlorodibenzo-p-dioxin)1,2,3,7,8-PeCDF (pentafuran)2,3,4,7,8-PeCDF (pentafuran)1,2,3,4,7,8-HxCDF1,2,3,6,7,8-HxCDF (hexafuran)2,3,4,6,7,8-HxCDF (hexafuran)1,2,3,7,8,9-HxCDF1,2,3,4,6,7,8-HpCDF(Heptafuran)1,2,3,4,7,8,9-HpCDF(Heptafuran)1,2,3,4,6,7,8,9-OCDF(Octafuran)TEQ
