Abstract

Soil contamination is an important issue for European environmental policy, since it represents potential hazards for human health and the ecosystem. This paper presents a case study from Greece. A historic metallurgy complex will be re-used for establishing the Lavrion Technology and Cultural Park (LTCP). Intensive mining and metallurgical activities that took place in the broader area for the last 3000 years have caused soil pollution, particularly with metals and metalloids. Because remediation is presently prohibitively expensive, a risk assessment methodology based on U.S. EPA guidance [1–5] was used to quantify human health hazards, implement immediate cost-effective countermeasures to ensure protection of human health, and provide time and data needed for the final remediation scheme to commence. Results indicated an excessive risk with respect to arsenic, mainly through the ingestion route, meaning that covering the top soil with the appropriate materials (limed sand and gravel) will exclude the particular “pathway” and eliminate hazards for a considerable amount of time.
