2.5.6
Laboratory Turnaround Time.
*****************************************************************
This section should include specifications from the chemist as to
the turnaround time required for completed data reports to be
generated from the laboratory. The Contractor will include this
in the SAP.
The project chemist should consult with the users of the data to
determine whether expedited reporting is necessary. The usual
turnaround time for reporting data to a customer from a contract
laboratory is approximately 30 days. The usual turnaround time
for reporting data to a customer from a QA laboratory is
approximately 30-45 days. An additional fee is usually attached
per sample when expedited turnaround times are specified in a
SOW.

2.5.7
Off-gas Emission Air Samples.
*****************************************************************
The off-gas emission of hazardous substances during a site
remediation utilizing the S/S process may pose health risks to
site workers and to the nearby public. Therefore, monitoring of
emissions released during the mixing and testing phases of the
treatability study may need to be performed. Measurement of off-
gas may help verify if contaminants will be released during full-
scale S/S treatment. However, off-gas emission measurement is
difficult. Often times measurement of off-gas emissions involves
little more than holding a photo ionization detector above the
sample. Factors such as height above the sample, temperature of
the sample, and airflow will affect the results. If measurement
of off-gas emissions is critical, testing should be performed in
an enclosed specifically designed vessel. The Contractor should
propose emissions monitoring/sampling techniques sufficient to
characterize any off-gassing potential of the waste.

2.5.8
Investigative-Derived Wastes (IDW).
*****************************************************************
The project chemist and geologist will need to estimate the
approximate volumes and types of IDW that will be generated
during the treatability study. Types of IDW that could be
generated include the following:
-Soil cuttings
-Personnel protective equipment (PPE)
-Disposable equipment (DE)
