What is the best procedure to take actual samples from a dredge discharge line?
Picture the discharge pipe as the hands of a clock with 12 being at the top, the best locations are at 4 and 8 on the dial. This is not exact but will give fair results. If monitoring is required on a continuous basis, use a tap off the discharge line with a valve. Do not put your hands or hold a bucket in the main discharge outflow. Injury may result.
