Dredging activities often result in the suspension of sediment into the water column in the vicinity of the activity. Sediment release to the aquatic environment and the effects of this release are often the prime environmental concern associated with dredging. As a consequence, the accurate monitoring of suspended particulate matter (SPM) concentration is of considerable importance to the industry.

The successful implementation of sustainable dredging operations often requires an effective monitoring programme to be established, which will include the collection of measurements of SPM concentration. Monitoring costs can be significant for dredging projects (up to 5 per cent of the contract value). Dredging is a highly competitive business so sensibly minimising the cost of the monitoring activities is important. However if a selected monitoring contractor has staff who are a little inexperienced, or not so focused or informed with respect to achieving high accuracy, what might the implications of this be for a project?
