“…Mapping of the vulnerability to groundwater contami-nation is indeed a powerful tool for communication between groundwater investigators and those working in water resources and land use planning and management. Nevertheless, one should never lose sight of two realities (Foster et al 2013): primarily, all vulnerability assessments symbolise a 'best professional synthesis' of available information, and also, all vulnerability maps are a screen-ing tool to identify where priority protection measures are likely to be required to manage a potential groundwater contamination threat.…”

The excessive use of pesticides and fertilisers in agriculture has generated a decrease in groundwater and surface water quality in many regions of the EU, consti-tuting a hazard for human health and the environment. Besides, on-site sewage disposal is an important source of groundwater contamination in urban and peri-urban areas. The assessment of groundwater vulnerability to contami-nation is an important tool to fulfil the demands of EU Directives. The purpose of this study is to assess the groundwater vulnerability to contamination related mainly to agricultural activities in a peri-urban area (Vila do Conde, NW Portugal). The hydrogeological framework is characterised mainly by fissured granitic basement and sedimentary cover. Water samples were collected and analysed for temperature, pH, electrical conductivity, chloride, phosphate, nitrate and nitrite. An evaluation of groundwater vulnerability to contamination was applied (GOD-S, Pesticide DRASTIC-Fm, SINTACS and SI) and the potential nitrate contamination risk was assessed, both on a hydrogeological GIS-based mapping. A principal component analysis was performed to characterised pat-terns of relationship among groundwater contamination, vulnerability, and the hydrogeological setting assessed. Levels of nitrate above legislation limits were detected in 75 % of the samples analysed. Alluvia units showed the highest nitrate concentrations and also the highest vulner-ability and risk. Nitrate contamination is a serious problem affecting groundwater, particularly shallow aquifers, especially due to agriculture activities, livestock and cesspools. GIS-based cartography provided an accurate way to improve knowledge on water circulation models and global functioning of local aquifer systems. Finally, this study highlights the adequacy of an integrated approach, combining hydrogeochemical data, vulnerability assessments and multivariate analysis, to understand groundwater processes in peri-urban areas.

“…Considering the specific contamination sources, the operation and maintenance of tubular wells may result in contact between the contaminants and the water within the wellbore, or can facilitate it through the flow in the open spaces between the tubes and the ground (ANDERSON, 1987;HEATH, 2004;FOSTER et al, 2013), thereby enabling negative impacts on public health.…”

“…The assessment of groundwater vulnerability is a very used tool throughout the world for management measures adoption (FUEST et al, 1998;JACKSON;DWARAKANATH, 1999;AL-ZABET, 2002;HIRATA;ANDREO, 2013;ODLING et al, 2015). Mapping vulnerability provides the spatial basis for an effective and sustainable management of groundwater resources as it allows identifying how natural aquifer properties and human made pressures can affect groundwater resources quality (FOSTER; HIRATA; ANDREO, 2013;SRIVASTAVA et al, 2013;JANG et al, 2016).…”

Assessing potential for contamination and exploitation conditions of water resources, better protection and conservation strategies can be established (NOBRE et al, 2007;ZUQUETTE;PEJON, 2009;LASAGNA;CAVIGLIA;LUCA, 2014;COSTA et al, 2015c).…”

Assessment of groundwater contamination potential using geological, hydrological and hydrogeological attributes, is an efficient mechanism of sub-surface water resources protection and conservation. However, usually this method does not take into consideration the potentially polluting human activities, either in punctual or diffuse sources, or because the relative importance of the attributes are not considered. The paper proposes a multi-criteria approach as a way of solving this gap, reducing subjectivity and considering land use/cover due human actions influence in the process. The study was developed in Araras river watershed (Paraná Basin, Brazil) using rock, groundwater, relief, soils, and land use/land cover classification, employing multi-criteria analysis and data of contamination sources. The potential contamination classification showed the predominance (54% of the area) of very high and high potential, especially due to geological environment conditions (exploitation areas and groundwater recharge of the Itararé Aquifer -clastic sedimentary and free flow). The contaminant sources analyzed are located mainly in higher potential contamination areas. Keywords:Groundwater; Water quality; Water contamination; Multi-criteria analysis. RESUMOA avaliação do potencial de contaminação da água subterrânea a partir dos atributos geológicos, hidrológicos e hidrogeológicos, é reconhecida como um mecanismo eficiente de proteção e conservação dos recursos hídricos de subsuperfície. No entanto, tal método por vezes apresenta como deficiências a desconsideração das atividades humanas que são potencialmente contaminantes, seja na forma de fontes pontuais ou difusas, ou por não considerar a importância relativa dos atributos na análise. Visando contribuir para a solução dessa lacuna, o presente trabalho se valeu de análise multicritério como forma de reduzir a subjetividade dessa análise e de informações de uso e cobertura do solo e de fontes de contaminação para tratar os efeitos da ação humana no processo. O trabalho foi desenvolvido na Bacia Hidrográfica do rio das Araras (Bacia do Paraná, Brasil) a partir do tratamento dos dados de substrato rochoso, hidrografia, relevo, solos, classificação de uso e cobertura do solo usando análise multicritério e dados de fontes de contaminação. A classificação do potencial de contaminação mostrou a predominância (54% da área) de áreas classificadas como potencial muito alto e alto, especialmente em função do ambiente geológico (áreas de explotação e recarga do Aquífero Itararé, sedimentar clástico e livre). As fontes contaminantes analisadas se localizam principalmente nessas áreas com maiores potenciais de contaminação.
