The daily log should be <br />printed in waterproof ink, and should contain a detailed signed and dated description of the sampling <br />activities. The description should be detailed enough to enable participants to accurately and <br />objectively reconstruct the daily events at a later time. If corrections aze necessary, these should be <br />made by drawing a single line through the original entry (so that the original entry is legible) and <br />writing the corrected entry alongside. The correction should be initialed and dated and may require <br />a footnote explaining the correction. <br />The following information should be recorded: <br />- Names of all personnel on site <br />- Dates, weather conditions, and times <br />- Location and well number <br />- Condition of the well <br />- Decontamination information <br />- Calibration information <br />- Time ofoccurrence and nature of any malfunctions offield measurement instruments <br />- Initial static water level and total well depth <br />- Calculations (e.g., calculation of purge volume) <br />- Field data (pH, conductivity meter, thermometer) <br />- A list of all samples collected which includes sample numbers, times, matrix, <br />analysis to be performed, sampling location, and COC and sample seal numbers <br />- A list of all QA samples (blanks, duplicates, etc.) <br />Agapito Associates, Inc. <br />
