• Support site health and safety implementation (JHAs, tailgate meetings, PPE use) and maintain a strong safety culture during all field activities.

• 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.
