Footnotes:

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

^b Concentrations and initial identifications were determined using gas chromatography/mass spectrometry (GC/MS) with electron capture detection (ECD).

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

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

^e Percent recoveries for the internal standards (surrogates) averaged 120%, CV = 8%, n = 27.

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

^g Identification of analyte was confirmed by gas chromatography/mass spectrometry.

^h The brackets indicate that due to the very small sample size the values should be considered semiquantitative.

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

^j The percent recovery of the surrogate standard was calculated using tetrachloro-m-xylene as the internal standard.

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

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