Preparing for global warming
Article Abstract:
Engineers must address structural damages caused by climatic changes including the potential effects of global warming. The recorded rise in sea levels and the greenhouse gases which may induce climatic change have underscored the importance of analyzing the probable impact of global warming especially to coastal structures. Engineers need to derive a risk analysis method which can quantify the amount of risk and establish facilities at risk. Effects of globalwarming can be further reduced by recording climatic changes and upgrading existing structures and the construction industry.

Reassessing the risk assessment
Article Abstract:
The EPA's tendency of focusing most risk assessments on the evaluation of worst-case impacts using a variety of conservative input assumptions and analytical techniques has caused engineers to design overly protective remedies while forcing cleanup costs to soar. This problem stems from the evolution of risk analysis techniques which have been developed for a variety of purposes and are now widely and inappropriately adapted to assess risks relating to site-specific contamination problems. Recommendations on how risk assessments can become as realistic as possible are provided.

Coal-gas conundrum
Article Abstract:
Investigation of coal tars found at former manufactured-gas plants show that the subsurface behavior of these wastes is more complex, the contaminants often more widespread and remediation often more difficult than originally believed. New rules by the EPA has even reclassified coal-tar-contaminated materials as characteristic hazardous wastes. In this regard, a Superfund site in Fairfield, Iowa currently being remediated is presented and analyzed.
