Abstract
Based on analysis of water sampled from a 2km range along the Tuo River,this paper disclosed current situa-tion of the groundwater quality of villages along the Tuo River: 0-10m groundwater,seriously polluted,mainly class V water;10-20m slightly polluted,mostly III,some IV;20m and below,basically unpolluted,good quality,largely III. Pol-lution is substantially sourced from river water,backward flow from river in flooding season,river water irrigation,ex-cessive use of fertilizer and living sewage.关键词
