RTC for Draft LL1-4 Remedial Action Completion Report Cmt.# Page # Line # Comment spelling on entries prior to submitting. A-77 Appendices (specific) On the Kemron Sample Extract Log Sheets – most of these were not reviewed and dated by a supervisor. Should be signed and dated in future projects. Key places where this should have occurred are on L071004 pg 21 and in L0711600 and L0711045 (page numbers cut off) where information was struck from or added to the note fields. A-78 Appendices (specific) Several sample receipt forms (groundwater samples) indicated that the metal samples were not preserved with nitric acid. Any project impact? A-79 Appendices (specific) Lab personnel should be instructed to use the one line strike out and initial method for making corrections. Most times this was done, but there were a number of times when this protocol was not followed. A-80 Appendices (specific) App D (L0708235) pg 166 – no recovery listed for Phenol – d5. (This occurs in a few places where recoveries are not listed.) A-81 Appendices (specific) App D (L0708235) pg 242 – missing entries on QCMRL samples. A-82 Appendices (specific) App D (L0708235) pg 470 – the extraction anomaly field references a lab accident. Additional details should be provided if lab accidents occur in future projects. A-83 Appendices (specific) App D (L0708235) pg 1227 – The notes indicate that the trip blanks had bubbles. Recommendation No response required – please note for future work.

Samples were not preserved in the field with nitric acid; however, the receiving lab performed nitric preservation immediately when samples were received. The Shaw project chemist has reviewed this issue and has determined that there was no project impact related to the delay in nitric preservation. The lab will be reminded of the required policy for future work. Comment noted – we will revisit this with the lab for future reports.

RTC for Draft LL1-4 Remedial Action Completion Report Cmt.# Page # Line # Comment Verify that future trips do not have bubbles. If these came from the lab – ask them to QA their trips better. A-84 Appendices (specific) App F (A7130241) pg 4 of case narrative. The text indicates that the temperature of the cooler (upon receipt) was 12.7 degrees C. Page 16 of the report indicates that the samples were not in contact with the coolant. It appears that this sample was also sent via courier and may not have had time to reach the target range of 2-6 degrees C. In future efforts, please be aware of packaging, i.e; using bubble wrap or some other material to prevent bottles from breaking, but also using enough ice to get the samples down to the proper temperature. A-85 Appendices (specific) In future projects, please ensure that the COCs are completely filled out – ex. page 775 of L0710422. Chains should have the full name of the person relinquishing the samples, not just initials. A-86 Appendices (specific) In future projects please ensure that the proper protocol for making corrections is used, i.e. one line strikeout and initialed (ex. page 882 of L0710423). A-87 Appendices (specific) L0710819, pgs 18 and 20 indicate that the surrogate or spike compound is out of range. It appears to be in range looking at the presented data. A-88 Appendices (specific) L0711004 – pg 719 indicates that the samples were received out of hold time. However, the COC on pg 718 indicates that they were received within the correct holding time. Recommendation No response required – please note for future work. No response required – please note for future work. No response required – please note for future work. No response required – please note for future work. No response required – please note for future work. Response over sampling procedure requirements for all samples with field personnel. Comment noted – we will revisit this with field crews and go over sampling procedure requirements for all samples for future work. IN addition, we will ask them lab to notify us verbally of any incident such as this so that the option of resampling is still available. Comment noted – we will revisit this with the lab for future reports and go over sampling procedure requirements for all samples with field personnel. Comment noted – we will revisit this with the lab for future reports and go over sampling procedure requirements for all samples with field personnel. Comment noted – we will revisit this with the lab for future reports and ask them to be more diligent with their reporting criteria.
