Development of Well Vulnerability Maps for Multiple Wells Using Backward-in-time Transport Modelling

چکیده
Well vulnerability maps can be used to quantify the potential impact of contaminant sources on a well or well field. Well vulnerability can be expressed in terms of the expected contaminant concentration in the extracted well water and the time history of these concentrations, thus accounting for dilution in the well by mixing with clean water. The information contained in the vulnerability maps provides a sound quantitative basis for the management of contamination risk. RÉSUMÉ Les cartes de vulnérabilité des puits peuvent être employées pour mesurer l'impact potentiel des sources de contaminants sur un puits ou un groupe de puits. La vulnérabilité peut être exprimée en fonction de la concentration prévue des contaminants extraits de l’eau du puits et de l’historique de ces concentrations, en tenant compte ainsi de la dilution dans le puits par le mélange avec l'eau propre pompée. L'information contenue dans les cartes de vulnérabilité fournit une base quantitative solide pour la gestion du risque de contamination.
