装置が求められている。 Shallow groundwater is an aquifer within 60 meters of the surface. Due to the shallow depth of the water, it is not filtered by the deep bedrock, and there is a high possibility of contamination from industrial wastewater and pesticide residues on the farmland. Drinking polluted groundwater has a serious impact on people's health.
In recent years, various contaminant transition models have been developed for simulating the movement and transition of agricultural chemicals, including pesticides, and their residues in soil and groundwater. These limited studies do not truly reflect the actual complex and varied field conditions, and there is still a lack of monitoring equipment for the analysis and treatment of shallow groundwater contaminants. Therefore, there is a need for a shallow groundwater contaminant monitor that can optimally address these issues for complex and variable field conditions.
