Seeing the wide earth, and thinking about the shape of the natural environment tomorrow. Through soil remediation technology, which includes soil and subsurface water surveys, research and treatment, we are committed to preserving the irreplaceable environment of the earth we live on. Returning the water and soil needed to achieve a coexistence between human beings and nature to their original, natural states: a key problem that must be resolved immediately. Tsuchiya-gumi is steadily accumulating experience in soil and subsurface water surveys and related treatments, while actively pursuing R&D into new soil remediation technologies. Our goal is to provide the optimal solution to preserving the global environment and protecting the futures of future generations. According to the Japanese Ministry of the Environment, there were a cumulative total of 2,070 surveys related to soil contamination as of FY2002. Of these, the majority (1,082) involved soil contaminant levels in excess of established environmental standards, and this trend has been rising in recent years. •Stronger government action related to contamination of soil and subsurface water, such as establishing standards for soil contamination. •Implementation of ISO14001 standard, and increase in voluntary soil and subsurface water surveys based on it. •Increase in sale of plant sites due to shift in manufacturing activity overseas, corporate bankruptcy and restructuring, leading to soil contamination issues. •Increase in surveys related to requests for communication of soil contamination survey reports to government, and requests for disclosure of soil contamination information by residents and government. •Active approach to environmental issues by corporations worried about their corporate image and decline of asset value. * "Outline of Survey Results Related to FY2002 Soil Contamination Surveys, Corrective Measures and Current Status," Environmental Management Bureau, Ministry of the Environment Tsuchiya-gumi is working on a range of soil remediation technologies, including surveys of soil contamination and the construction of cleansing systems, to provide more sophisticated and effective approaches. Through a partnership with Zueblin Utweittechnik GmbH, a general construction firm in environmentally-sensitive Germany, we are improving our technologies to propose and implement effective and low-cost methods.
