Abstract

Abstract:

In this paper, a chemical device workshop in Jiangsu Province was selected as the investigation object. Soil and groundwater samples from different locations in the workshop were collected by drilling, and the types, concentration and distribution characteristics of pollutants in soil and groundwater were detected and analyzed. The results show that the soil and groundwater in the workshop are polluted to a certain extent: the concentration distribution of pollutants in the soil are closely related to the lithology, the lithologic soil layer with poor permeability often leads to accumulation of pollutants; due to the shallow groundwater level and the good permeability of soil lithology, pollutants are not easy to remain in the soil environment for a long time, but easy to migrate from the soil environment to the groundwater environment, resulting in more serious pollution in groundwater. The pollutants in the soil that exceed the standard are benzene and cobalt, which are mainly distributed in shallow miscellaneous fill and silt layer. Many pollutants in groundwater exceed the standard, including benzene, 4-chloroaniline, petroleum hydrocarbon, manganese, cadmium, lead, sulfate, fluoride and ammonia nitrogen. The relationship between the distribution characteristics of pollutants and the properties of pollutants, soil lithology was analyzed to provide the basis for site selection of chemical companies, and pollution prediction, prevention and control.

Key words: soil, groundwater, pollution characteristics, soil lithology
