Abstract |
At the well field "De Groeve", located in the northern part of the Netherlands, over 8 million m³ of groundwater is abstracted annually. Just north-east of the well field approximately 30 million m³ of brackish water with a chloride content up to 900 mg/l is present within the exploited aquifer. The phenomenon is supposed to be of Eemian origin, due to transgression of the sea in that period. Geo-electric soundings have shown the lens to be of finite extent. Shape, size and location are affected by groundwater flow and thus by the abstraction. The study deals with prediction of chloride content in the mixed raw water in the next century. With the help of a groundwater solute transport model, these and questions concerning the operational scheme of the well field can be answered. It is shown that remedial action to prevent the chloride content exceeding an arbitrary 100 mg/l standard is not likely to be necessary. |
