<br /> Comments:
<br /> •water and vapor samples are reported in pg/L,soil/sludge/solid samples in mg/kg,product/oil/non-aqueous liquid samples and all TCLP&SPLP
<br /> extracts are reported in mg/L,wipe samples in pg/wipe.
<br /> ND means not detected above the reporting limit;N/A means analyte not applicable to this analysis.
<br /> #surrogate diluted out of range or surrogate coelutes with another peak.
<br /> h)lighter than water immiscible sheen/product is present;i)liquid sample that contains greater than-1 vol.%sediment;j)sample diluted due to high
<br /> organic cone nt/matrix interference;k)reporting limit near,but not identical to our standard reporting limit due to variable Encore sample weight;m)
<br /> ortinIg limit raised due to insufficient sample amount;n results are reported on a dry weight basis; see attached narrative.
