Introduction:
In early August, 1997, Mr. James A. Ploscyca of Environmental Efficiency was contracted to
compile and tabulate various environmental data associated with the Warren County Landfill site.
This compilation of data was completed and presented to Mr. Kelly at a meeting which took place
on September 2, 1997.
Review of the tabulated data indicated that the most common contaminant being detected in the
samples was Octachlorodibenzodioxin (OCDD). This compound was reported in every
groundwater sample collected at the site, but was also detected in many of the field and laboratory
blank samples. In an effort to verify the validity of the OCDD results, Mr. Ploscyca was requested
to evaluate the data for possible field or laboratory contamination.
The evaluation utilized a USEP A, Region IV document entitled "Data Validation Standard
Operating Procedures for Polychlorinated Dibenzodioxin and Polychlorinated Dibenzofurans"
September 1996, as guidance. The primary focus of the data evaluation was Section VII of the
document (See Attachment 1) which addresses method blank evaluation.
Summary of Findings:
The following tables list samples by analytical groupings referred to as Sample Delivery Groups or
SDGs. The laboratory utilizes SDGs to track internal laboratory quality control associated with
particular samples. Each sample grouping has one or more Method Blanks associated with the
analysis of samples. The table lists samples in a particular SDG and then the associated Method
Blank results.
The most common compounds detected in the samples were HPCDD and OCCD and the third
column in the table lists their respective concentrations in each of the samples and blanks. A
designation of "Plus" in the third column indicates that additional compounds beyond HPCDD
and OCCD were detected in the sample.
The values listed in column 4 represent the concentration levels found in the blanks multiplied by
a factor often. The EPA data validation document (See Attachment 1) states:
"Any compound detected in the sample that was also detected in any associated blank is not
reported if the sample concentration is less than ten times (1 Ox) the blank concentration. "
If the sample exceeded the Blank cutoff level, column five indicates an "R" flag which signifies
that the ·sample results are rejected due to serious deficiencies in the ability to analyze the sample
and meet quality control criteria. The presence or absence of the analyte cannot be verified.
Page 18 of the EPA document also indicates that data qualification should be based upon
comparison with the associated blank having the highest concentration of a contaminant.

Associated blanks include the extraction method blanks.
The highest water extraction blank was BL0414WB with HPCDD and OCCD concentrations of 4
and 140 pg/L respectively. A level of 140 pg/L of OCDD indicates a severe laboratory
contamination problem which may be reflected in the reported sample concentrations.
Samples with a "RR"qualifier indicate they are rejected since their concentrations are less than
1 Ox the levels found in the highest extraction blank. The highest soil extraction blank was
BL0414SA with HPCDD and OCCD concentrations of 1.1 and 31 ng/Kg respectively. Samples
qualified with an asterisk (*) appear to be valid reported concentrations according to the EPA
(I Ox) rule. Unfortunately, the "R" or "RR" flag was determined to be applicable in the majority of
cases.
In conclusion, it is my recomendation that extreme caution be used when attempting to utilize this
data to make important environmental decisions. There is clear evidence of widespread sample
contamination during sample processing at the laboratory. The presence ofthis contamination
makes it difficult, if not impossible, to rely on the generated data with any degree of confidence.
Since the scope of contamination was so broad, (not limited to merely a couple of blank samples),
it is difficult to have confidence in the data set as a whole, since it may not accurately reflect
actual field conditions.
There were two water samples, JDH and QAR which yielded relatively high concentrations of
analytes compared to the other samples collected. It may be prudent to take a closer look at these
locations if additional analytical work is performed.
Please do not hesitate to contact me at [phone] if you have any questions or comments on
this report.
Sincerely,

VALIDATION DATA QUALIFIER DEFINITIONS
The following definitions provide brief explanations of the
qualifiers assigned to results in the data validation process.
J The analyte was positively identified; the associated
numerical value is the estimated concentration of the
analyte in the sample.
R The sample results are rejected due to serious
deficiencies in the ability to analyze the sample and
meet quality control criteria. The presence or absence
of the analyte cannot be verified.
U Not detected above the Detection Limit (DL).

VII. METHOD BLANK ANALYSIS
A method blank should be extracted with each batch of
samples. The matrix for the method blank should be similar
to the associated samples.
Criteria:
1. The method blank should be analyzed on each DB-5 column
instrument used to analyze the associated samples. In
addition, a blank must be analyzed each 12-hour shift,
after the analysis of the continuing calibration and
prior to the analysis of the samples. This blank may
be the associated method blank, a method blank
associated with a different batch, or a system blank.
The use of instrument blanks is acceptable for DB-225
column analyses.
2. Laboratory method blanks should not contain any
2,3,7,8-substituted PCDD/PCDF in amounts greater than
the concentration of the lowest calibration standard.
Non 2,3,7,8-substituted compounds or other potentially
interfering compounds should not be present in amounts
greater than the concentration of the lowest
calibration standard, assuming a response factor of 1.
Action:
1. If the appropriate blanks were not analyzed with the
frequency described above, then the data reviewer
should use professional judgement to determine if the
associated sample data should be qualified. The
reviewer may need to obtain additional information from
the laboratory.
2. If a target compound is found in a blank but not found
in the sample, no action is taken. If the contaminants
found are interfering non-target compounds at
significant concentrations, then this should be noted
in the report narrative.
3. Action in the case of blank contamination depends on
the circumstances and origin of the blank.
Qualification should be based upon comparison with the
associated blank having the highest concentration of a
contaminant. Associated blanks include the extraction
method blanks, the 12-hour shift blank(s) and the
Region IV blind blank. Field and equipment blanks are

not used for data qualification.
Any compound detected in the sample that was also
detected in any associated blank is not reported if the
sample concentration is less than ten times (l0x) the
blank concentration. Typically, the quantitation limit
is raised to the concentration found in the sample.
If the compound is present in the sample in an amount
less than the detection limit (DL), then the DL should
be reported with the U flag. If the compound is
present in the sample in an amount greater than the DL
but less than 100, report the next highest amount,
using one significant figure, with the U flag. If the
compound is present in the sample in an amount greater
than the DL and greater than 100, report the next
highest amount, using two significant figures, with the
U flag.
If use of the l0X rule causes elevated detection limits
to be reported for any congeners, apply the MB"
qualifier to these congeners. The B qualifier flag is
to be applied to these congeners on the internal Form I
only. The B qualifier is not to be reported on the
final Data Report Sheet.
Additionally, there may be instances where little or no
contamination was present in the associated blanks, but
qualification of the sample was deemed necessary.
Professional judgement should be used in these
situations. An explanation of the rationale used for
this determination should be provided in the review
narrative.
4. If gross contamination exists (i.e., saturated peaks),
all affected compounds in the associated samples should
be considered to be unusable (R flag), due to
interference. This is a contract issue and should be
regarded as an action item.
5. If an instrument blank was not analyzed following a
sample analysis which contained an analyte(s) at high
concentration(s), sample analysis results after the
high concentration sample must be evaluated for
carryover. Professional judgement should be used to
determine if instrument cross-contamination has
affected any positive compound identification(s).

6. Blanks or samples run after a Region IV blind spike,
matrix spike or standard should be carefully examined
to determine the occurrence of instrument or syringe
carry-over. Since the efficiency of sample transfer
can vary dramatically according to apparatus and
operator techniques, professional judgment should be
used in each case to determine whether sample or blank
results are attributable to carry-over. Professional
judgement should be used to determine if blank results
which are possible artifacts of carry-over should be
used in determining contamination.
7. When there is convincing evidence that contamination is
restricted to a particular instrument, matrix, or
concentration level, professional judgement should be
used to determine if the lOX rule should only be
applied to compare contaminated blanks to certain
associated samples (as opposed to all samples in the
case ).
