Section 3 • • Surveying and Sampling <br /> • Sample location <br /> 3.5.4 SAMPLE SHIPMENT AND CHAIN OF CUSTODY <br /> All samples collected for analytical testing will be delivered to an approved analytical laboratory <br /> within 48 hours of collection, or within method holding time, which ever is shortest. During <br /> sample shipment, samples will be kept on ice or synthetic substitute (e.g. "blue ice") in an <br /> insulated container at a maximum temperature of 4°C. <br /> A chain of custody record, which documents possession of samples from time of collection to <br /> laboratory analysis, will be maintained. Each person who has possession of the samples will <br /> complete applicable sections of the form when samples are received or relinquished and when <br /> sample possession is transferred. <br /> The chain of custody form will be sent in the shipping container along with the samples. The <br /> sample collector will have the receiving personnel of the laboratory sign the chain of custody <br /> form to complete documentation of sample possession from time of collection to delivery to the <br /> laboratory. The laboratory will provide a photocopy of this form for the sample collector's <br /> records. <br /> 3.6 SCHEDULE <br /> Installation of the monitoring wells are contingent upon written Regional Water Board approval <br /> of this Groundwater Monitoring Well Installation Workplan and schedules of well drilling <br /> contractors. The following schedule provides a reasonable timeline for completion of <br /> monitoring well installation and related activities. A well survey and initial water samples will <br /> be collected soon after completion of the wells and as part of the next regularly scheduled quarter <br /> groundwater monitoring event. <br /> Table 3-2 <br /> Tentative Schedule of Well Completion (2007) <br /> Task Initiation Date Completion Date <br /> Regional Board Approval of Workplan April 30 May 31 <br /> Selection of a Drilling Contractor June 1 June 30 <br /> Install Monitoring Wells July 1 July 30 <br /> Monitoring Well Survey August 1 August 30 <br /> Monitoring Well Installation Report November 30 <br /> ApHI 2007 City of Ripon Wastewater Treatment Facility <br /> 3-5 Groundwater Monitoring Well Installation Workplan <br />
