✦ Synopsis

Environmental contamination in cold regions poses unique problems. It affects traditionally pristine areas and presents substantial operational difficulties. The extreme temperature range, soils and geology, the unique biological diversity, the freezing and thawing of pollutants, and the impact of human activities make environmental site assessment and remediation a challenging task. Based on papers presented at an international workshop held in Anchorage, Alaska, Contaminant Hydrology: Cold Regions Modeling provides insight into areas such as: Problems of contaminant hydrologyStrategies for development of cost effective amelioration proceduresBasic guidelines for conducting groundwater modelingFeasibility and computer model studiesAppoximately 50% of the earth's land mass is frozen at some time during the annual cycle. While we know a lot about contaminant fate and transport in cold regions, we must gain a better understanding of the effects of contamination and predicting the effectiveness of remedial actions. Contaminant Hydrology: Cold Regions Modeling provides this knowledge, making it easier to choose cost-efficient and effective methods.
