After the Mobile Information Teams come engineers, surveyors, drillers and dam builders-trained largely by the U.S. and equipped with $2,500,000 worth of American machinery. Since 1950 the U.S. has granted Thailand more than $290 million in nonmilitary aid. Two years ago, only one-third of the U.S. aid was going to the northeast; today the northeast is getting about two-thirds of the total...
...Cobre, a tiny copper town run by a subsidiary of Baron Guy de Rothschild's Société Minière et Métallurgique de Penarroya. For 35 years the mineowners had channeled their slag into a reservoir behind a 230-ft. earth dam. Just below the dam were the wooden huts of the town's 400 miners. When the tremors came, the dam gave way, and the thick, muddy waste exploded out across the valley, burying 200 people in seconds. One woman who saw it coming managed to scramble up a slope in time...
...damage was estimated at between $50 million and $100 million. With his ministers, Frei mapped out relief and reconstruction programs, ordered an inquiry to determine whether the mining company or government inspectors were guilty of negligence in permitting the miners to live at the base of the El Cobre dam...
...Colorado is a life-giving stream for much of the arid U.S. Southwest and for Mexico's Mexicali Valley. Under a 1944 treaty, the U.S. promised to share the river for irrigation. Mexico built a dam one mile below the border, spider-webbed the once desolate Mexicali Valley with irrigation canals. Then in 1961, under the Wellton-Mohawk reclamation project in Arizona's Yuma Desert, U.S. cotton growers began draining salty irrigation water from their soil-and flushed the residue back into the river, whose salt content rose from a tolerable 800 parts...
...pressed hard for a solution. Under the new agreement-not a formal treaty -the U.S. will spend $5,000,000 to build a 13-mile drainage canal that will divert the salty water from the Wellton-Mohawk project into the Colorado River at a point safely below the Mexican Dam. If pollution remains dangerously high at the end of five years, the U.S. and Mexico will get together to figure out what else...
