u � Kellogg Garden Products ECO:LOGIC Engineering Groundwater Monitoring Well Installation Work Plan KELG04-001 11/10/2004 For example, the sample ID "KEL-051204-MW2-3" identifies the sample as having been collected at the Kellogg facility on May 12,2004 from MW-2 and as the third sample collected that day. Sample Labels Each sample container will be affixed with a label marked in permanent waterproof ink. Each label will include: o Sample identification number,as above o Type of sample o Date and time of collection o Name of collector o Analysis requested Sample shipment All samples collected for analytical testing will be delivered to an approved analytical laboratory within 48 hours of collection, or within method holding time. During sample shipment, samples will be kept on ice or synthetic substitute(e.g."blue ice")in an insulated container at a maximum temperature of 4°C. Chain of Custody A chain of custody record, which documents possession of samples form time of collection to laboratory analysis,will be maintained. Each person who has possession of the samples will complete applicable sections of the form when samples are received or relinquished and when sample possession is transferred. The chain of custody for will be sent in the shipping container along with the samples. The sample collector will have the receiving personnel of the laboratory sign the chain of custody form to complete documentation of sample possession from time of collection to delivery to the laboratory. The laboratory will provide a photocopy of this form for the sample collector's records. Field Ouality Assurance/Ouality Control All equipment used to obtain field measurements (pH meter, specific conductance meter, etc.) will be calibrated according to manufacturer's directions. Calibration will be performed prior to the beginning of the sampling event. WATER LEVEL MEASUREMENT Water-level measurements will be taken with an electronic tape (water-level sounder). All water-level measurements will be taken with the same water-level indicator to insure reproducibility of the results. Water levels will be recorded to the nearest 0.01 foot and will be referenced to the surveyed data point (north quadrant of the PVC well casing,and or notch carved into the PVC casing). SCHEDULE Installation of the monitoring wells is scheduled in the Regional Boards September 9, 2004 letter to be completed no later than April 30, 2005, subject to Regional Boards written approval of the Groundwater Monitoring Well Installation Work Plan. The proposed schedule, which follows, is the most rapid possible timeframe for Regional Board review of this workplan, installing the monitoring wells, scheduling sampling and surveying, and completing the installation report. Initial water samples will be collected soon after completion of the well construction. Subsequent water samples will be collected quarterly per the MRP. 9
