With the rapid development of society and economy, the process of urbanization is accelerating, and land resources are in short supply, many cities have moved industrial enterprises from the main urban areas out of the city, resulting in a large number of complex polluted sites. Our company has rich project experience in contaminated site investigation, familiar with the main product types, common raw and auxiliary materials and production processes of various industries, and has a number of intermediate and senior engineers and industry experts in environmental engineering, hydrogeology and related majors. At present, our company can undertake surveys of contaminated sites in different industries and types of land use, including typical industries such as pesticide chemical industry, fine chemical industry, coking, petrochemical industry, electroplating, and industrial parks, old towns, and farmland.
