Comment<br />
cross reference to end of Section 3.2.2.<br />
Also, add a statement that indicates <strong>the</strong><br />
integrity of <strong>the</strong> sampling, etc. was not<br />
compromised.<br />
A-13 Page 3-4, Line 18-19 Include a reference to use of temperature<br />
blanks<br />
A-14 Page 3-4, Line 28 Please clarify what is meant by “RVAAP<br />
Water Quality Criteria”? It is unclear as to<br />
what is referenced as <strong>the</strong>re is nothing<br />
used by that designation.<br />
A-15 Page 3-5, Line 19 Does <strong>the</strong> text indicate that <strong>the</strong>re was some<br />
impact from lab contamination? Please<br />
clarify if lab contamination is cited.<br />
Recommendation<br />
Response<br />
integrity of <strong>the</strong> collected groundwater<br />
samples were not compromised.<br />
Field screening data met <strong>the</strong><br />
allowable criteria <strong>for</strong> sampling<br />
protocols applicable to <strong>the</strong> site.”<br />
Temperature blanks were sent with<br />
each cooler shipped to <strong>the</strong> laboratory<br />
<strong>for</strong> analysis. The text has been<br />
revised to state “Temperature and<br />
trip blanks consisting of…….”<br />
Shaw’s reference to <strong>the</strong> “RVAAP<br />
Water Quality Criteria” is incorrect.<br />
Per an email from Eileen Mohr dated<br />
November 7, 2007, Shaw was<br />
directed to compare <strong>the</strong> storm water<br />
sample detection results (or<br />
detection limits if non-detect) with<br />
site-wide surface water background<br />
and filtered/unfiltered groundwater.<br />
Reference to <strong>the</strong> “RVAAP Water<br />
Quality Criteria” in this section will be<br />
revised to state “Surface Water<br />
Background Criteria and Summary<br />
Statistics <strong>for</strong> Unconsolidated Zone<br />
Filtered/Unfiltered Groundwater<br />
Background Wells.”<br />
The contaminant concentrations in<br />
samples were not attributable to lab<br />
contamination. A sentence will be<br />
added to <strong>the</strong> end of <strong>the</strong> paragraph<br />
that states “The contaminant<br />
concentrations in samples were not<br />
attributable to lab contamination.”<br />
A-16 Page 3-10, Line 24 Add “as” after “as best” The text has been revised to read<br />
“as best as” as requested.<br />
A-17 Page 3-11, Table 3-1 Please confirm <strong>the</strong> total amount of Non-<br />
The actual tonnage transported off-<br />
Hazardous Soils excavated. Column<br />
site was 9488.63 tons. For report<br />
totals 9488 tons.<br />
purposes (and in <strong>the</strong> table), <strong>the</strong><br />
number was rounded up to get to<br />
9489 tons as shown. The table will<br />
be rectified so that <strong>the</strong> column in<br />
question sums to 9489 tons.<br />
