The utilization of numerical models in industrial pollution of geologic environment data processing and interpretation

Impact assessment methodology of industrial waste, implies not only the research of the geological environment, but also the determination of the most accurate dynamics and complex processes of pollution. In most of the cases, the primary data which describe the geological environment show a discontinuous image of the real investigated (natural) system. Often, increase in date volume, from in situ determinations or from laboratory, means a proportional and substantial increase of expenditures. Generally, the costs of direct geological investigation are high. The numerical model is the tool used by the environmental protection or environmental geology specialist, to replace this inconvenient. The numerical modeling is the main stage of the interpretation of the primary data and represents the base of the decisions making process. Also, processing of primary data and interpretation, using the water flow and transport models of pollutants, represent an important component of the investigation methodology for contaminated sites.
