西德是个青山绿水之国,然而最近几年却在闹供水紧张。克雷费尔德、科隆、曼哈姆和汉诺威等地都出现了地下水位下降的情况。莱茵河和欧登瓦特之间1,000平方公里的地区一向被称为“德国植物世界皇冠上的明珠”,近年来地下水位下降8米,水井干涸,溪水断流,上百万株橡树和山毛榉树枯死,肥沃的土地变为瘠壤。城市用水更成问题。汉堡和其他城市部分深水井已停止使用,因为水中含有砷和过多的氯化物。汉堡不得不从吕内堡调水以代替当地被污染的地下水。不莱梅市也铺设 West Germany is a green country, but in recent years has trouble downtown water supply.
