...filtered fresh water. But to clear the way for development, as well as to control floods, these wetlands have been largely drained away. This has not only threatened the quality of surface water but also cut off its flow into underlying aquifers, the porous rock formations that serve as subterranean reservoirs...
...made in the President's mind as events in the Dr. Strangelove world of nukes and launchers seem to be moving toward a final shape that has stunned the Pentagon, the industrial complex that builds the military's hardware and the defense experts of Congress. Subterranean shock waves came last week from the secret and cheerless Room 31074 in the Pentagon. There Richard D.

...street surfaces, curbs, gutters, sidewalks and stop lights. Water-main breaks and cracks in the pavement are rigorously recorded, as are the costs of repairing them. The city, for example, annually cleans out 26% of its sewers, and trouble-prone stretches of underground pipe are inspected by subterranean television cameras...

This is water that lies buried from a stretches feet to a half mile or more beneath the land's surface in stretches of permeable rock, sand and gravel known as aquifers.

While most ground water is believed to remain pure, concern is rising because it is one of nature's greatest nonrenewable resources. Unlike surface water or the air, ground water is all but impossible to purify...
