Abstract

The effect of "road salt" on the characteristics of Massachusetts drinking water supplies has been significant and cumulative rather than transient or seasonal. De-icing salt is essentially all sodium chloride. Calcium chloride accounted for only three percent of the total salt used. However, hardness content, as well as sodium ion concentration, has increased greatly in ground waters in the past decade. The changing composition of our water supplies has agricultural, economic, and public health implications. This study attempts to quantify the stoichiometry of these changes in concentration, which are in part due to an ion-exchange mechanism in the soil.

除冰盐对地下水特性的影响。
“道路盐”对马萨诸塞州饮用水供应特征的影响是显著的、累积的,而不是短暂的或季节性的。除冰盐基本上都是氯化钠。氯化钙仅占总盐使用量的3%。然而,近十年来,地下水中的硬度含量和钠离子浓度都有了很大的增加。供水结构的变化对农业、经济和公共卫生都有影响。本研究试图量化这些浓度变化的化学计量学,这些变化部分是由于土壤中的离子交换机制造成的。
