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.
