Air quality modeling's brave new world

Article Abstract:

Models-3, a new series of software systems touted as the next-generation air quality modeling system, promises to provide more reliable air quality management information faster and easier than current models. Since it incorporates models using regional-to-urban scales, modelers will be able to interactively develop regional air quality control methods while simulating urban air quality. The system is expected to facilitate model runs and presentation of information to policy makers in easy-to-understand, graphical methods.

A nickel-iron wall against contaminated groundwater: new reactive wall technology begins pilot study at Cape Cod military site

Article Abstract:

The Massachusetts Dept. of Environmental Protection (DEP) and the Dept. of Defense have constructed a permeable wall for the purification of contaminated water in the Massachusetts Military Reservation (MRI). The MRI of Otis Air Force base is a source of groundwater contaminants such as jet fuel, radioactive wastes and chlorinated compounds. The reactive wall technology is composed of nickel and iron which dehalogenates the contaminated water to produce non-toxic hydrocarbons and chloride.

Wetlands regulations need overhaul, says NRC report

Article Abstract:

A report issued recently by the National Research Council (NRC) reveals that changes are needed in the implementing rules of existing wetlands laws. The NRC report stated that although the wetlands regulations in themselves are scientifically sound, the manner in which these regulations are implemented is characterized by chaos and inefficiency. The NRC report also took a critical view of the fact that four different federal agencies exercise concurrent jurisdiction over wetlands.
