SOP 5 - FIELD LOGS/DOCUMENTATION <br /> During drilling and well installation, site and equipment conditions, variances from the <br /> specified sampling procedures, field observations, instrumentation readings, and measurements <br /> will be thoroughly documented by the sampling personnel. Soils encountered during drilling <br /> will be visually classified according to ASTM Test Designation D2488. Penetration blow <br /> counts for driven samples, and PID readings will be recorded on the drilling logs. <br /> During groundwater sampling, site and equipment conditions, purge rates and volumes, <br /> sampling procedures, field observations, instrumentation readings, and measurements will be <br /> documented. Groundwater sampling records will be completed for each well sampled. <br /> Sampling records will be accompanier) by a daily field report. The information to be <br /> included on well development and groundwater sampling records is as follows: <br /> -- Name of personnel performing sampling <br /> -- Weather conditions <br /> -- Total depth of well, casing diameter, and well volume <br /> -- Equipment calibration procedures and frequencies <br /> — Starting groundwater level <br /> — Time log of groundwater removal <br /> — Depth from which sample is collected <br /> -- Physical properties of groundwater (general clarity, temp., pH, EC, etc.) <br /> -- Total well volumes removed <br /> -- Flow rate of sample and purge pumps <br /> -- Time of sample acquisition <br /> — Decontamination procedures <br /> -- Sample containers (number and type) <br /> -- Analyses to be performed ; <br /> Description of field blanks, travel blanks, etc. <br /> -- Final depth to water <br /> -- Problems and resolutions <br /> I <br /> Wof$pin Wj%-074OWN-Retised A=1995 SOP 5 -1 - <br /> • <br /> &Associates <br /> I <br />
