**************************************************************************
Sample acquisition, chemical analysis and chemical parameter measurements
shall be performed so that the resulting data meet and support data use
requirements. The chemical data shall be acquired, documented, verified
and reported to ensure that the specified precision, accuracy,
representativeness, comparability, completeness and sensitivity
requirements are achieved.
1.4.3
Sampling, Analysis and Measurement
**************************************************************************
NOTE: The process to determine number of samples
and sample locations should be fully described here.
The specification should describe sampling
frequency (e.g. per excavated area, per a certain
number of cubic meters (yards) of soil, per a
certain number of drums) and general procedures for
sample locations (e.g. stained areas, grid pattern
over the excavated area, center of stockpile). This
provides adequate information for the Contractor bid
preparation, as well as for field oversight of
Contractor sampling, while allowing the Contractor
the flexibility to do the best possible job given
each site's unique characteristics.
Analytical method requirements for all project
chemical measurements must be specified, including
number and type of samples to be collected and
instrumental measurements. For National Priority
List (NPL) sites, chemical data requirements for
delisting the site from the NPL must be defined and
included.
For each type of sample, provide a table that
identifies the number of samples, including Quality
Control (QC) and Quality Assurance (QA) samples,
extraction and analytical methods, precision,
accuracy, representativeness, comparability,
completeness and sensitivity for analytical
determinations.
