Soil contamination investigation "Historical investigation"

Experienced engineers extract investigation points! We investigate the "risk of soil contamination" using existing materials such as maps and aerial photographs.

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

Soil Contamination Survey: Overview Survey / VOC Boring Survey

We provide highly accurate survey results! Experienced technicians will 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 investigation and the sampling methods vary depending on the location of potential contamination (such as surface, below buried pipes, under pits, or former ground surfaces) and the types of specific hazardous substances. 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, ensuring that we deliver speedy and highly accurate survey results. **Features** - Experienced technicians conduct soil and soil gas sampling. - In cases of mandatory surveys under prefectural regulations, we perform investigations and report results in accordance with 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.*

Soil Contamination Survey: "Soil Contamination Survey Analysis and Impact Prediction"

We conduct reproducibility analysis of contamination and predict the effectiveness of purification measures! We provide high-quality analysis.

In the "Soil Contamination Investigation Analysis and Impact Prediction Services," we conduct predictive analyses (groundwater contamination simulations) and risk assessments regarding the spread of harmful substances and purification effects. Our company utilizes the experience gained from soil contamination investigations and purification work to carry out appropriate modeling, conducting validation analyses of the models as much as possible, and providing high-quality analyses. We also offer proposals for the next step of purification countermeasure construction. 【Features】 ■ Cause investigation ■ Future predictions ■ Effect predictions of countermeasure construction ■ Effect predictions of purification countermeasures *For more details, please refer to the PDF materials or feel free to contact us.

Soil Contamination Survey "Detailed Investigation"

The investigation to be conducted as the next step of the overview survey! Mainly, we will carry out an investigation into the depth of contamination.

At Kyoa Development, we conduct a "Detailed Survey" as the next step following the overview investigation. The "Detailed Survey" is a depth investigation of contamination conducted when soil pollution is confirmed (when specific harmful substances exceed the standard values). Since the methods of investigation vary depending on the depth of the contamination source and the soil and geological conditions, these tasks require a wide range of specialized knowledge and know-how. 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】 ■ Environmental investigation drilling machine (Eco Machine) - Generates minimal excavation waste, resulting in less contaminated soil storage and processing - Fast excavation speed and easy machine mobility - Capable of drilling up to 20-30 meters ■ Providing speedy and highly accurate investigation results *For more details, please refer to the PDF materials or feel free to contact us.

Soil contamination survey: "Soil and groundwater analysis"

Conducting chemical analyses of soil, sediment, water quality, and industrial waste! We provide official methods such as notifications from the Ministry of the Environment and JIS standards.

At Kyoa Development, we conduct chemical analyses of soil, sediment, water quality, and industrial waste, and we perform "Soil and Groundwater Analysis." By conducting soil and groundwater analysis, we quantify the concentration of harmful substances in the soil and groundwater. Our company provides official methods such as notifications from the Ministry of the Environment and JIS standards. 【Features】 ■ Conduct chemical analyses of soil, sediment, water quality, and industrial waste ■ Quantify the concentration of harmful substances in soil and groundwater ■ Provide official methods such as notifications from the Ministry of the Environment and JIS standards *For more details, please refer to the PDF document or feel free to contact us.

Soil contamination investigation "Certified Survey"

We will conduct an investigation to obtain certification for compliance with standards on the land designated by the area!

At Kōa Development, we conduct "certification surveys" to obtain certification for land designated in specific areas. The density and methods of the survey vary depending on factors such as the depth of contamination and the condition of fill brought in from outside. Soil at depths where contamination has been confirmed cannot receive certification. There are two types of survey methods: pre-excavation surveys and post-excavation surveys. These tasks require a wide range of specialized knowledge and know-how. Our company continuously provides education and training for the technicians engaged in these tasks, enabling us to deliver speedy and highly accurate survey results. 【Features】 ■ Environmental survey drilling machine (Eco Machine) - Capable of soil sampling without using excavation water by applying vibration and rotation to the cutting edge - Generates minimal excavation waste, resulting in less contaminated soil to store and process - Fast excavation speed and easy machine mobility ■ Providing speedy and highly accurate survey results *For more details, please refer to the PDF materials or feel free to contact us.
