Soil contamination investigation

Soil measures to eliminate defect risks through voluntary pre-sale historical investigations to prevent unjust compensation claims and massive losses due to contractual non-conformity after land sale.

The biggest financial risk in land sales is the cost of dealing with soil contamination that may be discovered after the sale. If appropriate preemptive measures are neglected and the buyer pursues liability for contractual nonconformity after the handover, the seller may lose control over post-sale responses, leading to the worst-case scenario of being charged excessive cleanup costs or damages amounting to tens of millions of yen. This document explains the strategic value of "voluntary soil investigations" to minimize the "risk of defects in sales and purchases" associated with real estate sales in advance, thoroughly preventing unnecessary economic losses. By conducting voluntary historical investigations before the sale, it is possible to scientifically anticipate and understand the risks of underground infiltration of specific harmful substances, allowing for appropriate measures and the establishment of advantageous contractual provisions. This also helps optimize investigation costs by avoiding unnecessary comprehensive sampling. High-precision official analyses and reliable reports from Geotech, an investigation agency designated by the Ministry of the Environment, represent the most cost-effective pre-investment to robustly protect the seller's interests and management assets for the future.

basic information

This is a technical specification for voluntary soil surveys that balances cost performance and reliability. In historical investigations, in addition to a thorough examination of public documents, we utilize our own database to accurately assess the historical risks of the land. The sampling design adopts a phased approach based on risk, starting with surface soil sampling to keep initial costs down. The analysis process involves official testing of specific harmful substances (leachate and content) by registered analytical institutions in accordance with metrology standards, producing accurate measurement values under strict quality control, and creating efficient and smart survey reports.

Applications/Examples of results

It is utilized as a cost defense measure to prevent the occurrence of subsequent soil contamination remediation costs and damage claims during the sale of commercial real estate or former company buildings. It serves as supporting documentation to establish safety evidence before contracts are signed and to reject unreasonable discount requests during price negotiations in sales contracts. Additionally, it is also ideal as a decision-making tool for the finance and asset management departments of companies that want to efficiently identify environmental risks of their holdings within a limited budget and optimize future redevelopment plans and asset management.
