在被暴雪封路的高速公路上撒工业盐为主的融雪剂本来是抗击雪灾,保障交通之策,在抗击这场罕见的冰雪灾害中作出了巨大的贡献。但是,冰雪慢慢融化了,工业盐却也随着雪水流入公路周边居民的饮用水源中,形成了水源污染。 The industrial salt-based deicing salt on the highway closed by Blizzard would have been a tremendous contribution to fighting the snow storm and securing traffic and fighting against this rare snow disaster. However, as snow and ice slowly melt, industrial salt also forms a source of water pollution as snow water flows into drinking water sources of residents around the roads.
