Portable SERS Instrument for Explosives Monitoring
Abstract
In this project, a new method based on surface-enhanced Raman spectroscopy (SERS) has been developed, fielded, and validated for field analysis of explosives in water samples. The SERS technique offers enhance performance over colorimetry and other field screening techniques for groundwater well, direct push and process water monitoring. When compared to the reference laboratory HPLC Method 8330 and field screening methods, the SERS method has the potential to reduce the time, cost, and waste generated per analysis while providing discriminate quantification of multiple analytes, even those within a chemical class, in a single measurement. This project entailed three demonstrations at two Army facilities Alabama Army Ammunition Plant (ALAAP) and Umatilla Chemical Depot (UMCD). The ALAAP demonstration was aimed at establishing that a SERS instrument could be brought from the laboratory to the field and used to perform explosives analysis on samples collected from groundwater wells. The purpose for the two demonstrations at UMCD was to extend the applicability of the SERS method from conventional groundwater well monitoring to include expedited site characterization from a cone penetrometer (CPT), direct push platform and at-line remediation process monitoring.
