Abstract: The proposed project is a hazardous waste treatment plant, which includes hazardous waste landfill, workspace, hazardous waste storage area, living area, etc. The hydrogeological investigation is carriedout through drilling, hydrogeological mapping and survey , field water pressure test, constant-head injectiontest , pumping test and laboratory experiments. Through the hydrogeological investigation , the hydrogeologicalunit, groundwater flow direction, groundwater characteristics and the distribution characteristics of the naturalimpermeable layer of the project area are proposed to guide the construction of the relevant projects.

Key words: hazardous waste treatment plant, hydrogeological investigation, groundwater, engineering construction
