典型水源地地下水污染风险评价

Assessing Groundwater Contamination Risk in the Typical City Water Sources

地下水污染是由含水层本身的脆弱性与人类活动产生的污染负荷造成的。污染物的荷载可以控制或改变,但是含水层的敏感性是本质的、天然的特性。污染风险不仅取决于相对稳定、不宜改变的含水层天然特征,还取决于主观的污染活动。因此,从地下水天然防污性能、地下水污染源荷载以及地下水社会效益3个方面评价了典型水源地地下水受污染的风险。

Groundwater contamination is the vulnerability of the aquifer itself and the human activities causing the pollution load.Pollutant load can be controlled or changed,but the sensitivity is the nature of the aquifer.Risk of contamination depends not only on relatively stable,should not change the natural characteristics of the aquifer,but also on the possible existence of polluting activities.Therefore,assessed Groundwater contamination risk in Typical City Water Sources from three aspects,which is groundwater natural intrinsic vulnerability,groundwater pollution loads and social benefits.
