Many companies do “sediment spill monitoring,” but we offer “Sediment Spill Sedimentation Monitoring”
What is the Difference?
- Sediment spill monitoring is the monitoring of the sediment that exits the work area in suspension, i.e., it spills over from the work area into the surrounding environment
- Sediment spill sedimentation monitoring is the monitoring of the sediment spill that settles to the bottom after it has exited the work area and entered the surrounding environment
While many companies provide sediment spill monitoring, our system is to our knowledge the only system made to measure sedimentation in real time and provide actionable data to the project, to the auditing authorities, and or to the general public. Of course, it can also log data for later analysis.
Why do Sedimentation Monitoring?
- Environmental permits may include requirements to limit project-induced sedimentation in sensitive biotopes outside of the work area
- Even absent a legal requirement, the project owner may wish to monitor the sedimentation in real time so as to prevent sedimentation-induced damages, rather than to risk paying compensation later
- The project owner may wish to monitor the sedimentation in real time to avoid bad publicity, by being totally transparent
- The project owner may wish to collect statistically coherent data on sedimentation so as to have evidentiary proof that he did not cause sedimentation, thus pre-empting costly lawsuits
- In some projects the sedimentation monitoring can also be used to measure an intended effect of the project (the SediMeters can also be used for erosion monitoring, to be sure)
- Sediment is natural, and unless it is contaminated by chemicals adhering to the grains, sediment in and of itself is not a pollutant. It is only when it is in the wrong place at the wrong time that it is a pollutant. Therefore it makes sense to focus the spill monitoring efforts on the sediment that reaches sensitive biotopes, and ignore spill that is transported towards an area where it does no harm—or maybe even is desirable. This is why we at Lindorm advocate sedimentation monitoring: It focuses on the essential and can save money for the project owner, while perfectly well satisfying environmental concerns.
As we see, there are plenty of good reasons to carry out this monitoring even if not required by the authorities. It simply makes good sense for the investors in the company.
Our Cost-Effective Offer
We can design, plan, and execute sediment spill sedimentation monitoring using our unique and cost-effective method (white paper). The earlier we are brought into the planning process, the better. We do not charge consulting fees for consultation, so please contact us as soon as possible if you have a project which requires sediment spill monitoring, and especially if there are sensitive bottoms nearby that need to be protected.
Our CEO, Dr. Ulf Erlingsson, was the Swedish government’s external expert who supervised the largest and most ambitious sediment spill monitoring project in the world, that when building the Øresund Link between Sweden and Denmark. The Lindorm spill monitoring methodology is based on experiences from that project, and the company Lindorm was founded in order to bring this service to the market. The SediMeter™ SM2, SM3, and SM4 were all developed to fit into this sediment spill monitoring method, and they were complemented with software and hardware for allowing real time data acquisition and decision support, as we as for allowing effective auditing so as to gain compliance credibility.
Dredging projects can be challenging from a public perceptions point of view. We are here to help you every step of the way to execute the project in the most environmentally sensitive and sensible way possible, and to do so transparently, so as to minimize backlash from negative publicity or even worse, legal challenges. We have the expertise to help businesses work with nature. Send us a message, and Dr. Ulf Erlingsson will get in touch with you.
