Subaqueous soil analysis requires a specialised approach with modified procedures and materials when sludge and sediment is present. Abesim has the expertise to evaluate these samples both in situ and ex situ.

Pollution of sediments usually attaches itself to organic material and soil particles. The sediments can feed the water body with contamination/pollutants and may be responsible for the water quality not achieving the objectives or standards. The sediment survey and assessment, supplemented with other, site-specific data can determine the extent of the sediment contribution to exceeding the water quality standards.  

Before and during the dredging of streams, rivers and lakes, in harbours and offshore, we are able to evaluate the presence of pollutants in the sediments and give advice on the need for further processing, reuse or disposal.

The first phase consists of working with you in deciding which information is necessary in regards to your needs and how we can offer the best results in a cost effective manner. We’ll then determine which approach would offer the best results in your particular case.

On the basis of a more detailed site investigation, we can refine the chosen approach. We can then implement the selected strategy.

After completing our work, we thoroughly evaluate the results. If necessary we will then perform additional research to either confirm or disprove the results.
