Policy, planning, and resource protection: a groundwater conference for the midwest: proceedings, conducted at Kalamazoo, Western Michigan Univ., Nov. 12-13, 1987
摘要
It can readily be argued that groundwater is the environmental issue of the Eighties. In part that is true because we have begun to get a handle on the more visible forms of pol-lution affecting air and surface-water quality. Yet almost daily media reports of groundwater contamination, sometimes close to home, have become insistent reminders that this newly-apparent threat is slowly, invisibly moving beneath our landscape.
