Historically, industries were in harbour areas of cities for easy access to transportation of resources. Today, transforming former industrial areas into living spaces has become an attractive business. However, this transformation has often been challenged by high levels of soil contamination caused by the industrial use. Remediation measures are mandatory to ensure the public safety in the redeveloped areas. Detailed information about the contaminant type, distribution, and transport mechanisms is required to address the contamination issues. This paper suggests a workflow for investigations assisting decision making for construction work in redeveloped industrial areas. The workflow is applied to Horsens harbour (Denmark). In this area, renovation of the harbour walls introduces the risk of spreading of contamination to planned construction areas. The study demonstrates how detailed hydrogeological information about the site allows for scenario modelling of contaminant transport, guiding remediation efforts and aiding decision makers in developing the harbour area.

历史上，工业位于城市的港口地区，便于资源运输。如今，将前工业区改造成生活空间已成为一项有吸引力的业务。然而，这种转变经常受到工业用途造成的高度土壤污染的挑战。修复措施是强制性的，以确保重建地区的公共安全。解决污染问题需要有关污染物类型、分布和传输机制的详细信息。本文提出了一个调查工作流程，以协助重建工业区的建筑工作的决策。该工作流应用于霍森斯港（丹麦）。在这个领域，海港围墙的翻修带来了污染扩散到规划建筑区域的风险。该研究展示了有关该地点的详细水文地质信息如何允许对污染物运输进行情景建模，指导修复工作并帮助决策者开发港区。
