Reasons for slow progress in preliminary work of soil general survey project

The experience of the employees is relatively lacking, and the construction period of the remediation project is short.

1. Lack of experienced professionals in soil investigation and remediation.

2. The construction unit often pays insufficient attention to the secondary pollution caused by earthwork excavation, transportation and the discharge of accumulated water in the foundation pit during the restoration process, and the environmental supervision during the construction process lacks necessary monitoring means and emergency plans, which will cause secondary pollution to the surrounding air or surface water.
