d) All of the above
5. Which of these best describes the role of calibration in water quality monitoring?
a) Calibration ensures accurate measurement of water quality parameters like pH and dissolved oxygen. b) Calibration helps to identify the source of pollution in water bodies. c) Calibration is used to predict future water quality trends. d) Calibration ensures that water treatment plants operate efficiently.
a) Calibration ensures accurate measurement of water quality parameters like pH and dissolved oxygen.
Task: You are a technician responsible for calibrating a pH meter used to monitor the pH levels of wastewater discharged from a treatment plant. The pH meter is equipped with a digital display and has been used for several months without calibration.
Requirements:
Steps:
The correction for this exercise would involve a detailed explanation of the specific steps taken during the calibration process. It would include the actual readings obtained for each buffer solution, the adjustments made to the meter, and the results of the final test using the wastewater sample. The correction should demonstrate a clear understanding of the calibration procedure, the use of the calibration logbook, and the importance of ensuring accurate measurements.
