Site and field logbooks were completed to provide a general record of activities and events that occur during each field task. FDRs have been designated for each exploration and sample collection task, to provide a complete record of data obtained during the activity. Field Logbooks The field logbooks provided a daily handwritten account of field activities. Logbooks were hardcover books that were permanently bound. All entries were made in indelible ink, and corrections were made with a single line with the author initials and date. Each page of the logbook was dated and initialed by the person completing the log. Partially completed pages will have a line drawn through the unused portion at the end of each day with the author’s initials. The following information was generally entered into the field logbooks: • The date and time of each entry. The daily log generally begins with the Pre-Job Safety Brief; • A summary of important tasks or subtasks completed during the day; • A description of field tests completed in association with the daily task; • A description of samples collected including documentation of any quality control samples that were prepared (rinse blanks, duplicates, matrix spike, split samples, etc.); • Documentation of equipment maintenance and calibration activities; • Documentation of equipment decontamination activities; and • Descriptions of deviations from the work plan. Field Data Records Sample FDRs contain sample collection and/or exploration details. An FDR was completed each time a field sample was collected. The goal of the FDR was to document exploration and sample collection methods, materials, dates and times, and sample locations and identifiers. Field measurements and observations associated with a given exploration or sample collection task were recorded on the FDRs. FDRs were maintained throughout the field program in files that become a permanent record of field program activities. Sample Identification In order to ensure that each number for every field sample collected was unique, samples were identified by the sample location and depth interval, if applicable (e.g., MW-11S (5-6’). Samples were numbered in accordance with their sample location. Field Equipment Calibration Field sampling equipment (e.g., water quality meter) was properly maintained and calibrated prior to and during continued use to assure that measurements were accurate within the limitations of the equipment. Personnel will follow the manufacturers’ instructions to determine if the instruments were functioning within their established operation ranges. The calibration data was recorded on a FDR. To be acceptable, a field test must be bracketed between acceptable calibration results. • The first check may be an initial calibration, but the second check must be a continuing verification check. • Each field instrument must be calibrated prior to use. • Verify the calibration at no more than 24-hour intervals during use and at the end of the use if the instrument will not be used the next day or time periods greater than 24 hours. • Initial calibration and verification checks must meet the acceptance criteria recommended by each instrument manufacturer. • If an initial calibration or verification check fails to meet the acceptance criteria, immediately recalibrate the instrument or remove it from service. • If a calibration check fails to meet the acceptance criteria and it was not possible to reanalyze the samples, the following actions must be taken: • Report results between the last acceptable calibration check and the failed calibration check as estimated (qualified with a “J”); • Include a narrative of the problem; and • Shorten the time period between verification checks or repair/replace the instrument. • If historically generated data demonstrate that a specific instrument remains stable for extended periods of time, the interval between initial calibration and calibration checks may be increased. • Acceptable field data must be bracketed by acceptable checks. Data that was not bracketed by acceptable checks must be qualified. • Base the selected time interval on the shortest interval that the instrument maintains stability. • If an extended time interval was used and the instrument consistently fails to meet the final calibration check, then the instrument may require maintenance to repair the problem or the time period was too long and must be shortened. • For continuous monitoring equipment, acceptable field data must be bracketed by acceptable checks or the data must be qualified. Sampling or field measurement instrument determined to be malfunctioning was repaired or was replaced with a new piece of equipment. Sample Custody Requirements A program of sample custody was followed during sample handling activities in both field and laboratory operations. This program was designed to assure that each sample was accounted for at all times. The appropriate sampling and laboratory personnel will complete sample FDRs, chain-of-custody records, and laboratory receipt sheets. The primary objective of sample custody procedures was to obtain an accurate written record that can trace the handling of all samples during the sample collection process, through analysis, until final disposition. Field Sample Custody Sample custody for samples collected during each sampling event was maintained by the personnel collecting the samples. Each sampler was responsible for documenting each sample transfer, maintaining sample custody until the samples were shipped off-site, and sample shipment. The sample custody protocol followed by the sampling personnel involves: • Documenting procedures and amounts of reagents or supplies (e.g., filters) which become an integral part of the sample from sample preparation and preservation; • Recording sample locations, sample bottle identification, and specific sample acquisition measures on appropriate forms; • Using sample labels to document all information necessary for effective sample tracking; and, • Completing sample FDR forms to establish sample custody in the field before sample shipment. Prepared labels were normally developed for each sample prior to sample collection. At a minimum, each label will contain: • Sample location and depth (if applicable); • Date and time collected; • Sampler identification; and, • Analyses requested and applicable preservative. A manually-prepared chain-of-custody record was initiated at the time of sample collection. The chain-of-custody record documents: • Sample handling procedures including sample location, sample number, and number of containers corresponding to each sample number; • The requested analysis and applicable preservative; • The dates and times of sample collection; • The names of the sampler(s) and the person shipping the samples (if applicable); • The date and time that samples were delivered for shipping (if applicable); • Shipping information (e.g., FedEx Air Bill); and, • The names of those responsible for receiving the samples at the laboratory. Chain-of-custody records were prepared by the individual field samplers. Sample Container Packing Sample containers were packed in plastic coolers for shipment or pick up by the laboratory. Bottles were packed tightly to reduce movement of bottles during transport. Ice was placed in the cooler along with the chain-of-custody record in a separate, resealable, air tight, plastic bag. A temperature blank provided by the laboratory will also be placed in each cooler prior to shipment if required for the type of samples collected and analyses requested. Quality Assurance and Quality Control Samples The following Quality Assurance/Quality Control samples were collected during the proposed field activities: • Equipment rinse blanks (one per day or one per 20 samples); • Field Duplicates (one per 20 samples for field and lab duplicates) Equipment rinse blanks were collected from non-dedicated equipment used between wells and from drilling equipment between soil samples. The field equipment was cleaned following documented cleaning procedures. An aliquot of the final control rinse water was passed over the cleaned equipment directly into a sample container and submitted for analysis. The equipment rinse blanks enable evaluation of bias (systematic errors) that could occur due to decontamination. A field duplicate was a replicate sample prepared at the sampling locations from equal portions of all sample aliquots combined to make the sample. Both the field duplicate and the sample were collected at the same time, in the same container type, preserved in the same way, and analyzed by the same laboratory as a measure of sampling and analytical precision. Field QA/QC samples were analyzed for the same constituents as proposed for the soil and groundwater samples. Decontamination Procedures Decontamination Pad A decontamination pad was constructed for field cleaning of drilling equipment. The decontamination pad will meet the following requirements: • The pad was constructed in an area believed to be free of surface contamination. • The pad was lined with a water-impermeable material with no seams within the pad. The material should be easily replaced (disposable) or repairable. • If possible, the pad was constructed on a level, paved surface to facilitate the removal of decontamination water. This may be accomplished by either constructing the pad with one corner lower than the rest, or by creating a lined sump or pit in one corner. • Sawhorses or racks constructed to hold field equipment while being cleaned were high enough above ground to prevent equipment from being contacted by splashback during decontamination. Decontamination water was allowed to percolate into the ground adjacent to the decontamination pad. Containment and disposal of decontamination water was not required. At the completion of field activities, the decontamination pad was removed and any sump or pit was backfilled with appropriate material. Decontamination of Field Sampling Equipment Field sampling equipment was decontaminated between sample locations using potable water and phosphate-and-borax-free detergent solution and a brush, if necessary, to remove particulate matter and surface films. Equipment will then be rinsed thoroughly with tap water to remove detergent solution prior to use at the next sample location. Decontamination of Drilling Equipment Any downhole drilling equipment was steam cleaned between boreholes. The following procedure was used for field cleaning augers, drill stems, rods, tools, and associated downhole equipment. • Hollow-stem augers, bits, drilling rods, split-spoon samplers and other downhole equipment was placed on racks or sawhorses at least two feet above the floor of the temporary decontamination pad. Soil, mud, and other material were removed by hand, brushes, and potable water. The equipment was steam cleaned using a high pressure, high temperature steam cleaner. • Downhole equipment was rinsed thoroughly with potable water after steam cleaning. The clean equipment will then be removed from the decontamination pad and either placed on the drill rig, if mobilizing immediately to the next boring, or placed on and covered with clean, unused plastic sheeting if not used immediately.
