Notes:

(a) Error in conversion of unit from ppbv to umg^-3 for raw data

(b) Concentration of VOCs out of detection limit (DL) of GC-MSD, half DL substituted

(c) Invalid because concentration of benzene was relatively high in field blank sample, this could be due to leakage of valve. The canister was replaced afterward.

(d) Invalid because the concentration of trichloroethylene was extremely high ad compare with other samples obtained, this could be due to contamination of sample.

(e) Invalid because concentration of the pollutants were too low, this could be due to error with the GC-MSD system.

(f) Sample types: S = Field Sample, C = Collocated Sample, B = Field Blank
