7.6.6

Laboratory Logbook

Once the sample has been received in the laboratory, the sample custodian and/or

laboratory personnel should clearly document the processing steps that are applied to the

sample. All sample preparation techniques and instrumental methods used should be

identified in the laboratory logbook. Experimental conditions, such as the use of specific

reagents, temperatures, reaction times, and instrument settings, should be noted. The results

of the analyses of all laboratory quality control samples should be identified, specific to each

batch of ground water samples analyzed. The laboratory logbook should include the time,

date, and name of the person who performed each processing step.

Analytical Procedures

The QAPjP submitted as part of the permit application should describe in detail the

analytical procedures that will be used to determine the concentrations of constituents or

parameters of interest. These procedures should include suitable analytical methods as well

as proper quality assurance and quality control protocols. Minimum procedures specified in

Chapter One of SW 846 for QAPjPs should be satisfied.

The QAPjP included as part of the permit application should identify an analytical

method that will be used for each specific parameter or target analyte, and that can achieve

the required detection limits. The following should be addressed:

For SW 846 analytical methods, reference SW 846 and the analysis methods

(by method number), including all sample preparation methods. For modified

SW 846, or other standard methods, the analytical procedure and method

detection limits to be used should be documented in the format of a Standard

Operating Procedure (SOP).

For analysis by non SW 846 methods, the following should be provided:

approval of the Regional Administrator for standardized

methods;

for EPA or standardized methods, a reference to the source of

the method; and

for non standard methods, a complete SOP with method

detection limit should be included as an integrated part of the

S&A program to be approved by the Regional Administrator and

specified in the permit. Minimum procedures specified in

Chapter One of SW 846 for QAPjPs should be satisfied.
