Field portable XRF analysis of environmental samples

Area of Science:

• Environmental Science
• Analytical Chemistry
• Geochemistry

Background:

• Effective hazardous waste site management requires timely sample analysis for contamination characterization and remediation.
• Traditional off-site laboratory analysis often results in delays, hindering efficient data utilization.
• On-site analytical methods are crucial for rapid decision-making in environmental cleanup operations.

Purpose of the Study:

• To evaluate the utility of Field Portable X-ray Fluorescence (FPXRF) for on-site environmental sample analysis.
• To demonstrate how FPXRF can accelerate contamination characterization and support remedial actions.
• To highlight FPXRF as a viable alternative to slow off-site analysis.

Main Methods:

• Utilizing Field Portable X-ray Fluorescence (FPXRF) instrumentation.
• Performing in situ analysis of environmental samples, including soils and sediments.
• Analyzing thin films, particulates, and lead-based paint.

Main Results:

• FPXRF provides a rapid and effective analytical approach for on-site needs.
• The technique allows for timely data acquisition, supporting immediate response actions.
• Successful applications demonstrated for metals in soils, sediments, and lead in paint.

Conclusions:

• FPXRF is a critical tool for enhancing the speed and efficiency of hazardous waste site investigations.
• On-site analysis using FPXRF significantly reduces turnaround times compared to off-site methods.
• Implementing FPXRF facilitates better-informed and more responsive environmental remediation strategies.
