Environment & Remediation Dredging
Environmental and Remediation Dredging is the precise and careful removal of contaminated sediments to restore the health of a water body. This is a critical process in areas where toxins have settled due to industrial discharge or runoff.
Unlike navigational dredging, success is measured by the reduction of contaminants, not by volume or depth. The primary objective is to stop the spread of hazardous pollutants and improve water quality for human and aquatic health.
Key Remedial Applications
This highly specialized work requires maximum containment and precision:
- Contaminated Sediment Cleanup: Removing toxic materials like heavy metals, PCBs, and industrial waste from river and lake bottoms (known as hot spots).
- Dams & Desiltation: Removing fine, oxygen-depleting silt and sludge from reservoirs and lakes to restore water depth and quality.
- Sludge & Tailings Management: Containing and removing toxic industrial or mining tailings in controlled ponds and basins.
The Ellicott Solution: Precision and Minimal Turbidity
Remediation dredging requires specialized equipment designed to prevent the re-suspension and spread of contaminants. Ellicott focuses on maximizing the amount of solids removed while minimizing the disturbance to the surrounding water.
- Low-Turbidity Design: Our specialized cutterheads and suction systems are engineered to reduce water disturbance, minimizing the risk of pollutants spreading.
- High-Solids Management: Our pumps are designed to create a thick, dense slurry. This reduces the total volume of water needing dewatering and treatment onshore, saving significant time and cost.
- Precision Excavation: Modern dredging systems use advanced GPS and positioning to target specific "hot spots" for removal, ensuring only the contaminated material is excavated.
