The population of peninsular India relies heavily on groundwater for drinking purposes, agriculture and industrial needs. Critical to the well-being of this population is the judicious exploitation of this vital resource. India has made significant investments of physical resources and trained man-power over the past four decades towards a systematic exploration and development of groundwater resources. This goal will be greatly facilitated by directing the overall planning of these activities on the basis of a framework that is specific to the physico-chemical process that govern the hydrogeologic conditions of peninsular India. Competing with this need is the equally important need of providing the minimal requirements of clean water in critical regions of deficiency. The challenge is to formulate a plan that balances the two objectives in a complementary, winning manner. From a technical view point, very little attention has so far been devoted in peninsular India to the understanding of the vadose zone that spans the region between the land surface and the flucluating water table. A quantitative knowledge of the dynamics of water storage and release from this zone is of paramount importance to the management of groundwater resources in the peninsular Indian shields. The hydrogeology of peninsular India can offer exciting intellectual challenges to students of natural sciences.Keywords

Hydrogeological field observations indicatc that the river Palar, which now follows a south-easterly course in the vicinty of Kancheepuram, once flowed towards the north-east during quaternary times. The shift appears to have taken place in four stages. The shifts probably, suggest gently vertical movements to the north of the river. If such vertical movements have indeed occurred, It should be of interest to study their relation in regional vertical motions elsewhere along the east coast and their implications to regional hydrogeology of aquifers.Keywords

Over the past century and half, groundwater has played an important role in the economic prosperity of the United States. The groundwater profession which has contributed to this prosperity has grown through the contributions of the U.S. and State Geological Surveys, academia, and industry. A century ago, the energies of the profession were channeled towards discovering new sources of groundwater in a largely unexplored land, and exploiting the resources for maximum economic benefit. Experience has since revealed that groundwater systems are finite, and are intimately linked to surface water bodies and the biosphere. A consequence is that aggressive exploitation of groundwater can lead to unacceptable environmental degradation and social cost. At present, the groundwater profession is in a state of transition from one of discovery and exploitation, to one of balancing resource development with avoiding unacceptable damage to the environment. This paper outlines the history of the groundwater profession in the United States since the late nineteenth century, and speculates on what may lie ahead in the near future, as the profession makes the transition from discovering new sources of groundwater to one of better understanding and adapting to nature's constraints.Full Text
