Introduction In a recent study of public-supply-well water quality in the United States, nearly two-thirds of all samples from 932 public wells tapping 30 regionally extensive aquifers contained detectable amounts of drinking-water contaminants that originated entirely or primarily from manmade sources. Twenty-two percent of the samples contained at least one contaminant (manmade or naturally o...

Ultrasonic transmitters were surgically implanted into adult tautog (n=27, 400–514 mm TL) to document sea­ sonal occurrence and site utilization at four sites situated within known tautog habitat near Cape Charles, Virginia, in lower Chesapeake Bay. Tagged tautog were released at the same sites where originally caught within 2 h of capture. Sites were continuously monitored with automated acous...

The European Groundwater Directive could be improved by limiting the scopes of the Annexes I and II to the manmade and natural substances, respectively, and by defining a common monitoring protocol. The changes in the European landuse patterns, in particular the urban sprawl phenomena, obscure the distinction between the point and diffuse sources of contamination. In the future more importance ...

Effective disaster recovery planning, execution, and testing are essential to manage the risk of business interruption that arises from a myriad of sources such as fire, natural or manmade disasters, sabotage, or technical or human operational failures. The Municipal Software Services, Inc (MSS) case describes a company that was faced with a catastrophic fire. The MSS case provides a realistic ...
