Dredging is no longer just a part of industrial infrastructure development or the preparation for recreational activities: it’s also key to improving water quality and allowing ecosystems to thrive. Environmental dredging is a process that involves removing sediments and contaminated materials from lakes, rivers, estuaries, and underwater structures in order to protect aquatic life and human health. From sludge removal to shoreline repair, this practice has helped clean up contaminated environments all around the world.
This article will explain the importance of environmental dredging as well its benefits while discussing several different techniques used today.
What Is Remediation Dredging?
Dredging has been used in harbors and rivers for centuries as a way to aid in their navigation. It’s a proven and effective way of opening up waterways for increased usage. However, environmental dredging is a recent phenomenon and also an important one. Unlike navigation dredging, which measures the amount of material removed as a metric to judge success, environmental dredging measures the amount of targeted material removed as a metric for success.
This means that environmental dredgers are trying to remove certain contaminated materials while leaving uncontaminated materials intact, and minimizing the amount of water that is disturbed.
How Is It Done?
Because environmental remediation dredging needs to be so precise, it is carried out in different ways than navigational dredging. Typically, remediation dredging is carried out by either a mechanical or hydraulic dredging machine. Mechanical dredging usually requires the use of a bucket that collects contaminated sediments and then placed in a hopper or container. Hydraulic dredges loosen the contaminated sediments from the uncontaminated area with a cutter head and sucks the sediment into a holding tank.
In both cases, these contaminated sediments and materials are separated from the water that they were dredged in. This allows the contaminated sediments to be disposed of, or treated properly. This also allows the water itself to be treated before being returned to the water source it was taken from.
Because hydraulic dredging moves much more water and sediment to the shore in the form of a slurry, it has the potential to move more water, and disperse contaminated water to nearby water sources. As a result, much more monitoring of nearby water sources is conducted by dredging companies during a hydraulic dredge of contaminated sediments.
The long-term effectiveness of remediation dredging is that harmful contaminants have been removed from the sediments of a water source. This keeps the surrounding vegetation and animal populations healthy, as well as any nearby human populations healthy.
In the short term, there can be an increase in the number of contaminants being introduced into the water source, as the process of dredging can disturb these contaminated sediments, and pushing them out into the water source. This can be mitigated through the use of silt curtains, sheet piling, and air curtains.
Finding The Right Dredger For Your Project
While remediation dredging can be an expensive endeavor, sometimes it is the only way to remove large sections of contaminated sediment effectively. While it’s easy to get caught up in the short-term financial costs of a dredge rental project, U.S. Aqua Services also keeps the long-term environmental costs of a project in mind.
Our dredging equipment rental service uses cutting-edge environmental dredging techniques to ensure that the highest amount of contaminated sediment can be removed, while simultaneously minimizing the impact and disruption to surrounding ecosystems.

About U.S. Aqua Services
U.S. Aqua Services was created to support the dredging process in advancing commerce and responding to its many challenges. To accomplish this, our dredging company assembled an exceptional group of experienced individuals and a diverse inventory of dredge equipment.
We offer dredging equipment rental services so you can have access to the latest and greatest in dredging technology without having to pay to maintain it, transport, and store it, along with dewatering services.
With an emphasis on mobility, dependability, durability, diversity, efficiency, and safety, our dredging rental company can ensure that our different types of dredging systems are easy to move through any terrain and can work in the most rugged and remote environments. Our multi-function hydraulic systems are built with jetting and mechanical options that can efficiently move loose sediment or stiff layers of clay.
US Aqua services also and maintains a ready fleet of amphibious equipment capable of completing projects in some of the harshest and most remote environments. U.S Aqua is also the dealer for Louisiana of the amphibious vehicle Fat Truck. No matter the size or scope of the job or the remoteness of your work location, you can rely on Fat Truck’s industrial off-road utility vehicles to get the job done right.
