We provide highly accurate survey results! Experienced technicians conduct soil sampling and soil gas sampling.
At Kyoa Development, we conduct contamination confirmation surveys as the next step following historical investigations. The "Overview Survey" involves collecting and analyzing soil and soil gas samples to determine the presence of soil contamination by specific hazardous substances at 10-meter intervals. The density of the survey and the sampling methods vary depending on the location of potential contamination (such as surface, beneath buried pipes, under pits, or old ground surfaces) and the types of specific hazardous substances. These tasks require a wide range of expertise and know-how. Our company continuously provides education and training for the technicians engaged in these tasks, ensuring we deliver speedy and highly accurate survey results. 【Features】 ■ Experienced technicians perform soil and soil gas sampling. ■ For mandatory surveys under prefectural regulations, we conduct investigations and report results based on legal requirements. ■ We provide speedy and highly accurate survey results. *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.
