Comparison of Pumped and Diffusion Sampling Methods to Monitor Concentrations of Perchlorate and Explosive Compounds in Ground Water, Camp Edwards, Cape Cod, Massachusetts, 2004-05. Laboratory and field tests were conducted at Camp Edwards on the Massachusetts Military Reservation on Cape Cod to examine the utility of passive diffusion sampling for long-term monitoring of concentrations of perchlorate and explosive compounds in ground water. The results of laboratory tests in which diffusion samplers were submerged in containers filled with ground water containing perchlorate, RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine), and HMX (octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine) indicate that concentrations inside the diffusion samplers equilibrated with concentrations in the containers within the 19-day-long test period. The results of the field tests indicate generally good agreement between the pumped and diffusion samples for concentrations of perchlorate, RDX, and HMX. The concentration differences indicate no systematic bias related to contaminant type or concentration levels (December 2008, 26 pages). View or download at .

In-Situ Chemical Oxidation: A Study of the Current State of the Technology. This document was prepared by Matthew West during an internship with the U.S. Environmental Protection Agency, sponsored by a Cooperative Agreement with the University of Arizona. Chemical oxidation is one of the many different methods of site remediation that has emerged lately as an alternative method to traditional techniques. Chemical oxidation is based upon the theory that by introducing certain reactive chemicals into the contaminated aquifer, the contaminant in question can be converted into less harmful compounds in a relatively automated process. After the reactive chemicals (reagents) are introduced into the aquifer, they work by themselves and are driven by the internal chemical energy. Furthermore, chemical oxidation has been shown to be effective at the destruction of the dissolved phase of non-aqueous phase liquids (NAPL), which are known to be difficult to remediate through other tactics. Therefore, if administered correctly, in-situ chemical oxidation (ISCO) has the potential to be a low-cost, fast, effective, and relatively low maintenance remediation technology (August 2008, 9 pages).
