September 5.2001 immediately be labeled and logged onto a Chain-of-Custody document. The samples will be stored in packing material and placed in an iced cooler at 4°C for transfer to the certified laboratory with the Chain-of-Custody. 4.4.1 `Grab' Water Chemical Analyses Grab groundwater samples will also be analyzed at Halcyon using EPA Method 8260b for HVOCs. Note: The compounds will be reported as an 8010/601 list using a GC/MS method. 5.0 RIFS PHASE 1 REPORT OF FINDINGS Upon receipt of the analytical results, a report of findings will be generated. The report will include, but not necessarily be limited to, the following: • Site description; • Investigation methods and procedures; • Analytical methods and procedures; • Graphical and tabular representation of investigative data and results; • Conclusions and recommendations; and • If warranted, the recommendations will include methods and procedures and a Workplan for additional investigative work for the Phase 2 portion of the RIFS. 6.0 QUALITY ASSURANCE PLAN This section describes field and analytical quality-assurance procedures to be followed during the investigation and remediation. 6.1 Sample Collection and Handling Protocol Proper sample collection and handling are essential to assure quality of data obtained from a sample. Each sample, therefore, will be collected in a brass or stainless steel tube, preserved correctly for the intended analysis and stored for no longer than permissible holding time prior to analysis. 6.2 Sample Identification and Chain-of-Custody Protocol Sample identification and Chain-of-Custody procedures are designed to assure sample quality and to document sample possession from the time it is collected to the time of its ultimate disposal. The container for each sample submitted for analysis will have a label affixed with the identifying number or the number will be inscribed directly on the container. The analytical laboratory will assign a separate sample number unique to that sample for internal sample coordination and identification. A description of the sample including the sample number and other pertinent information regarding its collection and/or geologic significance will be written in field notes and/or a geologic boring log being prepared by the site geologist. These field documents will be kept in a permanent project file. All samples will be analyzed by a state certified laboratory for the analyses requested. A properly completed Chain-of-Custody Form will be submitted to the analytical laboratory along with sample. The laboratory's assigned number will be properly entered on the form.
