Cleanup of hazardous waste sites, contaminated landfills, and brownfields is slowed by the necessity of submitting separate samples for laboratory analysis.  On-site field screening instrumentation could appreciably  speed characterization at any stage of the cleanup process.  Physical Sciences Inc. proposes to extend the use of the Spark-Induced Breakdown Spectroscopy Cr/Pb soil monitor and the associated analytical method to the on-site measurement of Hg and Ba.  This instrument will be a simple, robust way to measure these toxic metals in soil.  Phase I will  involve finding analytical lines appropriate to the measurement of Hg and Ba.  We will upgrade the optical system of the monitor to these toxic metals which require greater sensitivity than Pb and Cr.  Additionally, we will streamline our analytical methodology for use on-site.

 

Commercial Applications and Other Benefits as described by the awardee:  Use of the field screening instruments will aid licensed site providers in the private sector.  They will benefit from reduced labor costs as site characterization is speeded.
