8.0 CHEMICAL DATA AND LABORATORY REQUIREMENTS 8. 1 Chemical Data Acquisition Plan (CDAP) . The plan shall describe the sampling and analyses, quality assurance and quality control methods, equip- ment, evaluations, reports and procedures as required for the work specified in this SOW. The plan shall describe field as well as laboratory procedures. The plan shall clearly describe how the AE shall ensure that sample integrity and chain of custody of all samples is not compromised prior to delivery to the laboratory. The plan shall be a brief and concise description of the field and lab work required. The existing RI/FS work plan (Ref 10. 12) shall be utilized as much as possible in the development of the plan. As a minimum, the level of data quality and quality control shall be equivalent to that required in the existing RI/FS work plans. The data quality and quality con- trol applies to both the field and laboratory efforts. Results of the field and laboratory controls shall be evaluated and placed in the analytical data submittal, and the draft and final Engineering Reports. The AE shall provide the laboratory QA/QC plan as an appendix to the LDAP. The plan shall address each requirement as identified in ER1110-1-263 (Reference 10.8) and shall be written in the format as shown in Appendix C, paragraph C.5 of that same docu- ment. 8.2 Laboratory Oualifications. The analytical laboratory utilized by the AE must be validated by the Corps of Engineers' Missouri River Division (CEMRD) as well as approved by the State of California to perform the analyti- cal methods required by this SOW. 8.3 Ouality Assurance Laboratory Requirements. The AE must provide coordination and quality assurance samples (collected and transported by the AE) to the Government Quality Assurance (QA) lab. The QA samples shall be splits of the required field control samples. Each field control sample col- lected shall be divided equally, one portion sent to the QA laboratory and the remainder sent to the AE's lab. QA samples include all sample matrices and analysis parameters. The AE shall provide the QA lab a two week notice of sample shipment. The Government will identify the QA lab. 8.4 Data Reporting Requirements. The AE shall provide the following data reporting elements; sample ID, sample receipt, organic and inorganic reporting, internal quality control reporting (lab blanks, surrogate spike samples, lab duplicates or matrix spikes) and field duplicates and blanks. This shall be reported in accordance with reference 10. 11. These data shall AA-26
