Dredged Material Dewatering/Engineering Intern

Engineering Intern – Dredged Material Dewatering

Employer: Cashman Dredging & Marine Contracting LLC Location: Quincy, MA

 Duration: Summer 2026 (10–12 weeks) Compensation: $20–24/hour

About the Role: Cashman Dredging is seeking a driven, technically curious college student to join our team for a summer internship focused on improving the dewatering of organically rich dredged materials.
This is not a typical field internship. The role is centered on understanding how water is retained in organic sediments and on exploring innovative methods to separate and remove it. You will gain exposure to both field operations and applied research, contributing to real-world dredging and marine construction projects.

What You’ll Do:

• Assist in evaluating methods to dewater organic dredged materials
• Support bench-scale and field testing (e.g., jar testing, filtration trials)
• Analyze sediment properties, including organic content and water retention
• Research and apply techniques to release “bound water” from organic material
• Document findings and help develop recommendations for field implementation
• Collaborate with engineers on active dredging and marine projects

What We’re Looking For:

• Current undergraduate or graduate student pursuing a degree in:
o Environmental Engineering
o Civil Engineering (Geotechnical focus preferred)
o Marine/Ocean Engineering
o Agricultural or Biological Engineering
o Chemical Engineering

• Strong interest in environmental systems, materials, or soil behavior
• Analytical thinker with problem-solving skills
• Interest in both lab work and field applications
• Basic proficiency in Excel or data analysis tools

Preferred (Not Required):

• Familiarity with concepts like:
o Bound vs. free water in soils or organic materials
o Polymer flocculation or water treatment processes
o Mechanical dewatering (centrifuges, filter presses)
• Experience with lab testing or research projects

What You’ll Gain:

• Hands-on experience with dredging and dewatering operations
• Exposure to innovative environmental and engineering solutions
• Mentorship from experienced industry professionals
• Opportunity to contribute to meaningful, real-world projects

How to Apply: Please submit your resume and a brief statement of interest through Handshake with your summer availability.
