<br /> NOTES:
<br /> (1) All values in parte per billion (ppb) except oil and grease in mg/kg (ppm).
<br /> (2) Analyses performed by Acurex Corporation. Result. reported in micrograms/kg (ppb).
<br /> (3) Standard detection limits were sometime. raised due to sample dependent matrix interferences.
<br /> (4) Soil samples from borings by Kennedy/Jenk./Chilton (B3/K,]C and Bll/KJC) were analyzed in October 1986. Results are shown in parentheses.
<br /> (5) * - Not detected at the method detection limit.
<br /> -- Compound not present.
<br /> (6) Non-standard compounds were identified and quantified only for those samples where significant non-standard peaks were present.
<br /> (7) (-) = Data not available for Kennedy/Jenkins/Chilton tests.
<br /> (8) Analysis performed by ANATEC Laboratories. Results reported in mg/kg (ppm).
<br /> (9) All positive values reported. In addition, methylene chloride, chloroform, 2-methylnaphthalene, ieophorone, and N-nitrosodiphenylamine
<br /> are included because positive values were reported in the Kennedy/Jenks/Chilton study.
