• Assist with waste characterization, profiling, and coordination of hazardous and non-hazardous waste disposal activities.
• Communicate effectively with project managers, clients (as appropriate), laboratories, and agencies; track field progress, and flag issues early.
• Maintain and calibrate field instruments; help improve field tools, checklists, and data workflows for efficiency and consistency.
