Description

The present invention relates to the technical field of evaluation and monitoring of contaminated sites, and specifically relates to a modular well for monitoring gas and groundwater in soil for evaluating contaminated sites.

Currently, there is little research on gas in the research on earthenware, but as a result of related research, the various gases present and generated in earthenware have become closely involved in geological science research and earthquake science research. We found that not only are they related to each other, but they are also closely related to the deterioration of ecosystems caused by environmental pollution. Therefore, by installing soil monitoring wells, we can measure the amount of various related gases contained in the earth's soil.
