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 110%, CV = 9%, n = 23. 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 Identification of analytes was confirmed by gas chromatography/mass spectrometry.

^h The concentrations of the analytes were calculated using the surrogate standard 4,4'-dibromooctafluorobiphenyl so that the data can be compared to previously analyzed data.

ⁱ The percent recovery of the surrogate standard was calculated using the 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.
