Measures for when purification is not carried out for contaminated substances, such as insolubility, containment, and diffusion prevention (barrier wells), etc.!
In addition to purification, there are measures such as solidification, containment, and diffusion prevention. Unlike purification work, contaminants do not disappear, so the designation of areas will depend on the measures implemented, as follows: (1) The required action area will be lifted, but it will be designated as a reporting area upon change of condition. (2) The required action area remains in place and is not lifted. Our company offers proposals for measures tailored to the specific site, supported by a wealth of skilled engineers. 【Types of measures other than purification】 ■ The required action area will be lifted, but designated as a reporting area upon change of condition. ■ The required action area remains in place with no lifting of the area. *For more details, please refer to the PDF document 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.
