Leakage detection at chemical waste disposal site

The waste disposal site of a pesticide chemical factory in Weifang City, Shandong Province, spans an area of 29,000 square meters. The project has ceased landfilling and is undergoing site sealing and covering. According to the "Pollution Control Standard for Landfilling of Hazardous Wastes" (GB18598-2019), after the construction of the disposal area is completed, an integrity test of the high-density polyethylene geomembrane's impermeability layer is required. On-site testing is conducted using the two-electrode method, and the data analysis of the potential changes in the tested area did not reveal any leakage points, ensuring the integrity and safety of the impermeable system.
