Environmental Research

We select the best methods to satisfy the aims of the project, and conduct surveys to obtain reliable data. Field surveys are conducted in consultation and coordination with the community, giving first priority to safety.

The environment around us consists of water, land, and air, which interact as a complex system. Obtainment of accurate environmental data through reliable scientific field survey is fundamental in identifying environmental issues, assessing environmental impacts and proposing effective countermeasures.

Our Environmental Survey Department has multiple bases nationwide to achieve high mobility. Our highly professional and experienced staffs will provide accurate environmental information, by conducting field surveys with state-of-the-art equipments, and careful analysis of the obtained data.
