Título:
On wellhead protection assessment methods and a case-study application in Montemor-o-Novo, Portugal
Resumo:
Groundwater is vulnerable to several kinds of pollution usually related to the development of anthropogenic activities. Nowadays, the wellhead protection areas and their corresponding restrictions are the most widely used instruments for protecting aquifers. After the description of the wellhead protection area and the presentation of Portuguese regulations that govern wellhead protection areas, a review of the methods applied to define wellhead protection areas in the case study area is presented. The study area is briefly described, including the wells used for public water supply, and the analytical methods for wellhead protection zones definition are applied, including the one suggested by the Portuguese legislation, as well as the ASMWIN numerical model. Finally, some conclusions were made, based on the achieved results.
