As a well-known testing institution in the industry, Standard Group's Ecological Environment has environmental laboratories around the country, which can provide soil detection services such as soil background, farmland soil environment, soil environment assessment of construction projects, soil pollution accidents, and site investigation in line with soil pollution risk control standards. In addition, Standard Group's Ecological Environment has been listed in the cultivated land quality standard laboratories of the Ministry of Agriculture and Rural Affairs, providing objective, impartial and independent testing services for the investigation and evaluation of cultivated land quality, the protection of cultivated land and basic farmland quality, the investigation, detection and evaluation.

Oil and gas recovery is a new technology of energy conservation and environmental protection. Oil and gas recovery technology is used to recover the oil gas discharged during the storage, transportation, loading and unloading of oil products, prevent air pollution caused by oil and gas volatilization, and eliminate potential safety hazards. Standard Group has mature leakage testing technology services of oil and gas recovery in the field of ecological environment to help enterprises reduce the risk of leakage.

Standard Group's Ecological Environment is one of the key laboratories in China that earliest to carry out solid waste testing and hazardous waste identification, and also one of the few third-party institutions in China that has the capability to test all six hazard characteristics of the GB5085 series. In June 2021, Standard Group's Ecological Environment became the first private third-party testing institution in China that obtained CNAS (ISO/IEC17020:2012) solid waste and hazardous waste identification and testing qualification. In September 2022, Standard Ecological Environment became one of the first registration institutions of the national hazardous waste identification information platform. Up to now, the number of environmental identification cases filed by Standard Hengli ranks first in the national hazardous waste identification information platform.

Soil gas investigation and sampling is an important means of soil contamination investigation in the aeration zone of organic-contaminated sites. Through soil gas investigation, the scope and depth of pollution can be understood more clearly, and the workload of borehole sampling can be greatly reduced. Soil gas investigation can provide relatively fast and low-cost site information to guide more expensive and accurate investigation techniques.
