mg/kg = milligrams per kilograms
B = Not detected substantially above the level reported
in laboratory or field blanks.
J = Analyte present. Reported value may not be accurate
or precise.
L = Analyte present. Reported value may be low. Actual
value is expected to be higher.
ND = Not detected.
N/A = Currently none available
"B2" = EPA classified probable human carcinogen
"C" = EPA classified possible human carcinogen
"D" = EPA--inadequate data to evaluate carcinogencity
"3" = IARC group--not classifiable as to carcinogenicity
Est = Estimated comparison value from
Rfd or oral slope factor
minimum = Lowest concentration of contaminant sampled
for all evaluated samples in the table.
lowest positive = If a contaminant is detected, this
would be the lowest concentration found for the contaminant that is above
"not detected".
maximum = Maximum concentration of contaminant detected
for all evaluated samples in the table.

Sampling date for all samples is March 1990 (Sample numbers CDF37, CDF38, CDF39, CDF40, CDF44).
mg/kg = milligrams per kilograms
B = Not detected substantially above the level reported
in laboratory or field blanks.
C = Confirmed by GC/MS.
J = Analyte present. Reported value may not be accurate
or precise.
L = Analyte present. Reported value may be low. Actual
value is expected to be higher.
ND = Not detected.
N/A = Currently none available
"B2" = EPA classified probable human carcinogen
"C" = EPA classified possible human carcinogen
"D" = EPA--inadequate data to evaluate carcinogencity,
"3" = IARC Group--not classifiable as to carcinogenicity
Est = Estimated comparison value from
Rfd or oral slope factor
minimum = Lowest concentration of contaminant sampled
for all evaluated samples in the table.
lowest positive = If a contaminant is detected, this
would be the lowest concentration found for the contaminant that is above
"not detected".
maximum = Maximum concentration of contaminant detected
for all evaluated samples in the table.
