Permanganate Treatment of DNAPLs in Reactive Barriers and Source Zone Flooding Schemes

Permanganate is a simple and common chemical, which has proven useful in oxidizing common chlorinated solvents. Due to the nature of oxidation, the byproducts and products are much less harmful than those from reduction-type remedial schemes, and the degradation process is rapid. The main goal of this project is to understand oxidative destruction of chlorinated solvents using potassium permanganate. The study has provided a theoretical basis for evaluating the feasibility of in-situ applications, to couple kinetic reaction with transport models, and to develop an appropriate field test for further assessing the approach.

Geospatial Information: Technologies Hold Promise for Wildland Fire Management, but Challenges Remain

A letter report issued by the General Accounting Office with an abstract that begins "Over the past decade, a series of devastating and deadly wildland fires has burned millions of acres of federal forests, grasslands, and deserts each year, requiring federal land management agencies to spend hundreds of millions of dollars to fight them. GAO was asked to assess opportunities to improve the way agencies manage fires through the use of geospatial information technologies, specifically, to (1) identify key geospatial information technologies for addressing different aspects of managing wildland fires, (2) summarize key challenges to the effective use of geospatial technologies in managing wildland fires, and (3) identify national opportunities to improve the effective use of geospatial technologies."
