Experienced engineers extract investigation points! We investigate the "risk of soil contamination" using existing materials such as maps and aerial photographs.
At Kyoa Development, we conduct "soil contamination risk" investigations through existing materials such as maps and aerial photographs, known as 'historical research.' This investigation involves collecting information regarding land use history and the history of hazardous substance usage, and based on this information, it is required to identify the types of specific hazardous substances and assess the risk of contamination. These tasks require a wide range of specialized knowledge and expertise. Our company continuously provides education and training for the technicians engaged in these tasks, enabling us to deliver speedy and highly accurate investigation results. 【Features】 ■ Experienced technicians extract investigation points ■ Conduct thorough material investigations and interviews without omissions ■ Investigate the historical location records and hazardous substance usage history of past facilities that no longer exist, as well as the status of notifications to authorities and the history of land development such as embankments and excavations ■ In cases of mandatory investigations under prefectural ordinances, conduct investigations and report results in accordance with laws and regulations *For more details, please refer to the PDF materials or feel free to contact us.

Company information
Koa Development was founded in 1953 (Showa 28), and thanks to your support, we have surpassed our 60th anniversary. We sincerely appreciate your long-standing support. Our company started as a geological survey firm and now primarily focuses on consulting services related to ground and groundwater, as well as soil environment consulting and purification and restoration projects to maintain a rich global environment. In our country, natural disasters such as the Great East Japan Earthquake and the Hiroshima heavy rain disaster have frequently occurred due to earthquakes, concentrated heavy rains, and typhoons. This is exacerbated by Japan's unique vulnerable ground and steep terrain, which amplify the scale of disasters. In such a natural environment, the role of our company as a group of ground experts (Geo-Doctors) has become increasingly important. We aim to further refine the foundational technologies related to ground and soil environments to provide optimal solutions and contribute to society, ensuring the development of social infrastructure that allows everyone to live safely and securely, as well as building a sustainable society. We will continue to prioritize our customers and strive for further development of our business, so we kindly ask for your guidance and encouragement.
