Footnotes:

^a The concentrations of the analytes and the percent recovery of the surrogate standard were calculated using tetrachloro-m-xylene as the internal standard.

^b The "less than" symbol (<) indicates that the analyte was not detected in concentrations above the stated value.

^c Concentrations and initial identifications were determined using gas chromatography (GC) with electron capture detection (ECD).

^d Concentrations less than 10 are rounded to one significant figure; concentrations greater than 10 are rounded to two significant figures.

^e Percent recovery for the internal standard (surrogate) averaged 94%, CV = 11%, n = 18. Percent recovery of the surrogate includes quality control samples.

^f Aldrin coelutes with an unknown compound. The concentration would not be higher than the stated value.

^g A large unidentified peak appeared at 45.03 minutes on the GC/ECD chromatogram.

^h A large unidentified peak appeared at 47.28 minutes on the GC/ECD chromatogram.

ⁱ These samples are duplicate analyses. The data for the duplicate samples are not identical which implies that the samples were not completely homogeneous.

^j Standard reference material from the National Institute of Science and Technology.

^k RSD is the relative standard deviation which is the standard deviation divided by the mean and expressed as a percent.
