Abstract

Contamination of land and groundwater by organic chemicals, particularly non-aqueous phase liquids, is a widespread problem that severely impacts human health, the environment and the economy at many urban sites all over the world. Complexity of the situation at these sites (in terms of contamination extent, boundary conditions/limitations, stakeholders, etc.) has led to the proposal of tiered frameworks for site investigation, risk assessment and management, e.g. in the United Kingdom and in the USA. Recent policies request an increased emphasis on modelling (e.g. EU Water Framework Directive). Within the suggested tiered frameworks a gap exists with respect to preliminary assessment methodologies that are capable of prioritising hot spots and streamlining the further planning process. In this paper, we give a brief glimpse of the decision support system CARO-Plus (Cost-efficiency Analysis of Remediation Options) designed to facilitate the establishment of appropriate, cost-effective management schemes for achieving site-specific remediation objectives within reasonable timeframes. Preliminary assessment shall quickly provide reasonable estimates of current and future risks, as well as of the costs of possible remediation (risk reduction) strategies.
