Ocena przekształceń chemizmu wód podziemnych w warunkach eksploatacji ujęcia Stara Łubianka-Dobrzyca dla Piły

Stara Łubianka-Dobrzyca well field location is unique in a regional scale due to character of land-use in the recharge area, dominated by forest (about 80% of the area is covered by forest). In the article the evaluation of groundwater chemistry changes during the well field exploitation had been made. For this purpose the detail analysis of land use was carried out. Data derived from groundwater flow model was also use for analyses. The study demonstrates that despite of lack groundwater chemistry changes, due to well field development it will be necessary to establish groundwater protection zone. The new protective monitoring system that includes both groundwater and surface water should be organized.

The article presents the classification of groundwater chemistry origin in the regional aquifer system located in the Wielkopolska region (west Poland). For identification of geochemical processes that affect groundwater chemistry factor analysis was used. Two groups of processes were identified: “anthropogenic” (i.e., caused by human activity) and “geogenic” (i.e., caused by natural geochemical processes). On the background of the natural changes of groundwater chemistry, the influence of ascent water on groundwater chemistry was identified. The presented results demonstrate that factor analyses is a reliable method for differentiation of both: natural and anthropogenic processes influencing groundwater chemistry, particularly during the early phase of anthropogenic groundwater chemistry transformations. The study demonstrates general usefulness of the groundwater chemistry differentiation for support identification of groundwater flow pattern. It also demonstrates the importance of using chemical data to verify multilayer aquifers connectivity.
