I certify that I have examined and I am familiar with the information submitted herein. The results pertain only
to sample(s) identified and their condition at time of receipt. Based on my inquiry of the individuals
responsible for the analysis, I believe the data to be true, accurate, and complete. Sampling and field data was
obtained from submitted documents. The analysis was authorized and commissioned by the client. The
resulting data are representative of the analysis conducted on the material/samples/articles provided by the
client (or client's representative) and it's/their condition at the time of analysis. The sample(s) were analyzed
in accordance with the appropriate method , however due to the inherent limitations of the methods,
microorganisms may avoid detection. BCS Laboratories offers no express or implied warranties concerning
the quality, safety, and/or purity of any sample, batch, source, or the process they are derived from. Quality
assurance controls were performed as outlined in the method and as per Good Laboratory Practices. The
analysis and results presented in this report meet the requirements of the standards of The NELAC Institute
(TNI), ISO 17025, and the FL DOH Environmental Laboratory Certification Program, as applicable unless
otherwise noted.

DATA QUALIFIER CODES
SYMBOL MEANING
B Results based on counts outside the acceptable range.
X Sample received without prior notification ordelayed delivery. Analysis performed outside of
associated method required QC data set (1 QC data set per 20 samples per 168 hours).
I Value is between the laboratory method detection limit &the practical quantitation limit.
J1 The sample matrix interfered with the ability to make any accurate determination.
J2 No Quality Control criteria exist for the component.
J3 The data are questionable because of improper laboratory orfield protocols.
L Off scale high. Actual value is known to be greater than value given.
N Presumptive evidence forthe presence of material. There is an indication that the analyte is
present, but the confirmation requirement was not met.
0 Sampled, but analysis not performed.
Q Sample held beyond the accepted holding time.
U Indicates that the compound was analyzed for but not detected. The specified component was
not detected. The reported value is the method detection limit.
V Analyte was detected in both sample and the method blank. Data may not be accurate.
Y Laboratory analysis was from an improperly preserved sample; the data may not be accurate
Z Too many colonies present (TNTC); the numeric value given represents the upper end of the
value that can be determined based on the volume.
7 Data are rejected and should not be used. QC data for analyte did not meet acceptance criteria.
Presence or absence of analyte could not be confirmed.
** Not reported due to interference.

I certify that I have examined and I am familiar with the information submitted herein. The results pertain only
to sample(s) identified and their condition at time of receipt. Based on my inquiry of the individuals
responsible for the analysis, I believe the data to be true, accurate, and complete. Sampling and field data was
obtained from submitted documents. The analysis was authorized and commissioned by the client. The
resulting data are representative of the analysis conducted on the material/samples/articles provided by the
client (or client's representative) and it's/their condition at the time of analysis. The sample(s) were analyzed
in accordance with the appropriate method , however due to the inherent limitations of the methods,
microorganisms may avoid detection. BCS Laboratories offers no express or implied warranties concerning
the quality, safety, and/or purity of any sample, batch, source, or the process they are derived from. Quality
assurance controls were performed as outlined in the method and as per Good Laboratory Practices. The
analysis and results presented in this report meet the requirements of the standards of The NELAC Institute
