Development Of An In Situ Passive Sampler For The Detection And Remediation of Explosive Compounds

Abstract : The abundance of aging unexploded ordnances (UXOs) in marine continental margins and nearshore areas is a global scale concern. Though it is impractical to retrieve these UXOs in their entirety it is critical to establish cost effective methods with which areas at risk may be monitored or evaluated for leakage and to measure concentrations of energetic compounds derived from UXOs to compare with water quality criteria. In this effort a novel passive sampling approach based on the introduction of samplers coated with ethylene vinyl acetate (EVA) were evaluated to assess the efficacy of these samplers to fulfill the gap in marine water and porewater monitoring. These initial efforts were dedicated to parameterizations identifying the uptake and depuration rates to confirm sufficient deployment times.
