When toxics meet metal

Article Abstract:

Zero-valent iron converts the chlorinated solvents present in groundwater into harmless substances eliminating the need to dispose the degraded products elsewhere. The chlorinated solvents oxidize the zero-valence iron to produce chloride and hydrocarbons leading to de-chlorination. This technology is cost effective and requires no surface equipment. Thus the surface area can be used for purposes such as parking areas. This technology can be used up to 75 feet below the surface and can save up to 50% of cleanup costs.

The train to the plane

Article Abstract:

The Port of Authority of New York and New Jersey has successfully been able to get the latest proposal for a light rail connection to John F. Kennedy International Airport off the drawing board and into construction phase. Politicians and citizens have opposed the idea since 1970. However, driving to the airport has become an urban nightmare. The 8.4-mile long AirTrain rail link will create a two-train system that will connect with subways and commuter trains. It will begin operations in 2002.
