地下水的开发、利用和保护,不仅关系到国民经济的发展,而且关系到人民生活和健康。吉林省现有九个市,具有人口集中,资源、水源和能源消耗以及污染源集中的环境特点。尤其是“三废”任意排放和环境保护差的城市,不仅大气、土壤和地表水污染严重,也使地下水遭到不同程度的污染,成为全省地下水水质恶化最重的地区。因此,保护城市地下水资源和防治地下水污染是我省城市经济建设和发展中的一个重要内容。一、地下水污染状况根据1979——1982年我站城市环境水文地质调查资料,各市第四系浅层地下水污染比较严重,主要污染物见表1。概括来说,全省城市地下水污染有以下特点:
The development, utilization and protection of groundwater are not only related to the development of the national economy, but also to people’s life and health. There are nine cities in Jilin Province, which have the characteristics of population concentration, resources, water resources and energy consumption, as well as environmental features with concentrated pollution sources. In particular, cities that emit “three wastes” and have poor environmental protection are not only seriously polluted by the atmosphere, soil and surface water, but also pollute the groundwater to varying degrees and become the worst deteriorating groundwater quality in the province. Therefore, the protection of urban groundwater resources and prevention and control of groundwater pollution in our province is an important part of urban economic construction and development. I. Groundwater Pollution According to the survey data of urban environmental hydrogeology of our station from 1979 to 1982, the pollution of shallow groundwater in the Quaternary in each city is relatively serious. See Table 1 for the main pollutants. In a word, the groundwater pollution in the whole province has the following characteristics:
