End Notes:
The test results listed in this report relate only to the samples submitted to the laboratory and as received by the Laboratory.
Unless otherwise noted, the test results for solid materials are calculated on a wet weight basis. Analyses for pH, dissolved oxygen,
temperature, residual chlorine and sulfite that are performed in the laboratory do not meet NELAC requirements due to extremely
short holding times. These analyses should be performed in the field. The results of field analyses performed by the Sampler
included in the Certificate of Analysis are done so at the client�s request and are not included in the laboratory�s fields of certification
nor have they been audited for adherence to a reference method or procedure.
The signature on the final report certifies that these results conform to all applicable NELAC standards unless otherwise specified.
For a complete list of the Laboratory�s NELAC certified parameters please contact customer service.
This report shall not be reproduced except in full without the expressed and written approval of an authorized representative of Air
Water & Soil Laboratories, Inc.

TIC Tentatively Identified Compounds are compounds that are identified by comparing the analyte mass spectral pattern with the NIST spectral library .
A TIC spectral match is reported when the pattern is at least 75% consistent with the published pattern. Compound concentrations are estimated
and are calculated using an internal standard response factor of 1.
PCBs, Total Total PCBs are defined as the sum of detected Aroclors 1016, 1221, 1232, 1248, 1254, 1260, 1262, and 1268.

Were Custody Seals used? If so, were they received intact?
Are the custody papers filled out completely and correctly?
Do all bottle labels agree with custody papers?
Is the temperature blank or representative sample within acceptable limits? (above freezing to 6°C) or received on ice and
recently taken?
Are all samples within holding time for requested laboratory tests?
Is a sufficient amount of sample provided to perform the tests included?
Are all samples in appropriate containers for the analyses requested?
Were volatile organic containers received?
Are all volatile organic and TOX containers free of headspace?
Is a trip blank provided for each VOC sample set? VOC sample sets include EPA8011, EPA504, EPA8260, EPA624,
EPA8015 GRO, EPA8021, EPA524, and RSK-175.
Are all samples received appropriately preserved? Note that metals containers do not require field preservation but lab
preservation may delay analysis.
