Data validation was performed using QAIQC criteria specified for each method in addition to .the
evaluation of holding times, instrument calibrations, method blanks, field duplicates, and analyte
quantitation and reported detection limits. Data qualifiers were assigned using standard CLP definitions
and flags.
Two types of data validation reviews were performed for all data received from the laboratory. The types
of reviews are referred to as "standard" and "summary" in the data validation reports. The "standard"
review refers to conducting a data validation review which requires spot checking the laboratory's raw
data package and calculations in accordance with the Functional Data Validation Guidelines. A
"summary" data validation review refers to conducting reviews which involve evaluating only the data
summary and QAIQC summary sheets provided with all data packages. The "summary" reviews do not
involve spot checking raw data packages and calculations. "Standard" data validation reviews were
performed on all of the Phase I data and on I0 percent of the total number of samples collected per media
and per individual type of analyses on the Phase I1 data. A "summary" data validation review was
performed on the remainder of the Phase I1 and I11 data.
Data validation memoranda for all laboratory results were prepared for each analytical data package and
are provided in Appendix L.
In general, the laboratory data were acceptable except where flagged by individual data qualifiers that
modify the usefulness of the individual values. Specific data qualifiers that affect data quality are
discussed in the relevant soil, surface water, groundwater, and sediment discussions (Section 5.0).
3.10.1.3 Asbestos
Asbestos samples were collected of "exposed insulation" on the walls of the abandoned mill building as
described in the draft RI Work Plan (Section 5.6). The samples were analyzed using polarized light
microscopy to determine presence of or absence of asbestos by Electron Microscopy Services Laboratory
Inc. (EMSL) in Seattle, Washington.
