  • Properties and Behavior of Radionuclides

    For the purposes of this document, radionuclides should be considered to have properties similar to those of other heavy metals.This does not imply that all radionuclides are heavy metals, but that the majority of sites requiring remediation of radioactively contaminated materials are contaminated with radionuclides that have similar properties. Like metals, the contaminants of concern are ...

  • Why perform 3D slope stability analysis

    Background The benefits associated with performing 3D slope stability analyses were expounded by Dr. Del Fredlund in the 1970s.  Over the years a number of 3D methods of analysis have been researched. These methods have ranged from the method of columns to approaches based on variational calculus, and more recently, the use of dynamic programming. The interest in 3D slope stability analysis ...

  • The New Environmental Insurance Products: When Does it Make Sense to Buy Them?

     Part One Introduction Real estate transactions with environmental problems often founder on attempts to shift the liabilities from one party to the other. In transactions with other types of problems, insurance is a popular risk transfer mechanism,  and is regularly used for that purpose, but it is used far less often when there are environmental risks. This so-called ...

  • Integrated Environmental Risk Management in Real Estate Transactions

     Traditional risk management posits a rational, five-step process for managing risks. The outstanding differences between this traditional process and the environmental risk management process lie in the technicality and complexity of step one (identifying and analyzing environmental risk) and of the first part of step two (examining the feasibility of  alternative risk management, ...
