Pro Tips

Environmental sampling for permitting purposes can be done at the same time as geotechnical investigations and can save time and money when done together.

Anyone scheduling for the retrieval and analysis of dredging samples for chemical analysis should assume 6-10 weeks. The process involves developing a sampling plan, submitting the plan to and getting it approved by the required agencies, retrieving the samples, and delivering the samples to the lab and waiting for results.

Activities such as dredge disposal and site remediation require soil samples to be taken prior to beginning construction, usually as a part of the permitting process.
