The Potent ‘Water Bombs’

Posted by on Nov-27-2010

On a fine day, I was surfing on the net and I came across an interesting fact. But it would be shocking for many in United States that they are living under the threat of a potential water bomb.

Yes I am saying about the dams in United States. There are 47,000 large dams across the world of which 6,375 are in USA. The construction of dams dramatically grew in USA during the post world war period, and over 150 dams were commissioned every year. But approximately one third of these dams are considered high or significant hazard to life and property as they have already passed its useful lifespan. These dams are expensive to maintain and the government consider it as an economic burden on the country. Many people living in these regions are not even aware of the issues relating the dams.

The dams are not only to threat to life but they also cause impact on the environment. In a latest research it has been found that dams have caused fragmentation of 60% of World Rivers and disruption of movement of around 75% species and an estimate of about 40 to 80 million people have been physically displaced due to construction of dams. In USA, a number of agencies are looking forward to upgrade the spillway capacity of dams. In a recent survey by EPRI/FERC showed that the reservoir sedimentation is becoming an issue in medium-sized dams.

Protests against building of dams are not new they have been seen all across the world. Though several environmentalists have stood against the construction of the dams their protests have never been fruitful. In USA, decommissioning of the dams has become a central part of policy debate, driven by environmental and social concerns and recently the decommissioning has been limited to smaller dams and older dams. There are several dams in USA which have the potential to cause a massive disaster.

Dams are deadlier than a nuclear bomb and if the necessary actions are not taken on time, the dams in USA can turn out to be gigantic water bombs.
