The Guyuan City, Ningxia hazardous waste landfill project features a total of 450 unit ponds, measuring 5m x 5m x 10m. After the impermeable construction is completed, the landfill is required to undergo integrity tests for the impermeable membrane in accordance with relevant specifications. On-site electrical spark testing revealed one point of mechanical abrasion leakage. After on-site repairs, the site was retested, and the results were confirmed by the owner, contractor, and supervision parties.
