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.

“…Whilst other work modelling abstraction has considered many other aspects of the impact of groundwater abstraction, as yet there has been no systematic evaluation of the potential impact on agricultural production. Other studies have considered the impacts on water quality within a GIS (Al-Adamat et al, 2003), the risk of pollution to groundwater (Lytton et al, 2003), the effect on natural vegetation of abstraction (Munoz-Reinoso, 2001), the impact of abstraction on wetland status (Acreman et al, 2000) and on fish stocks (Strevens, 1999). In this work we report on the assessment of crop vulnerability to water abstraction from the North Shropshire Permo-Triassic sandstone formations to augment the flow of the River Severn by the Environment Agency.…”

Water use is expected to increase and climate change scenarios indicate the need for more frequent water abstraction. Abstracting groundwater may have a detrimental effect on soil moisture availability for crop growth and yields. This work presents an elegant and robust method for identifying zones of crop vulnerability to abstraction. Archive groundwater level data sets were used to generate a composite groundwater surface that was subtracted from a digital terrain model. The result was the depth from surface to groundwater and identified areas underlain by shallow groundwater. Knowledge from an expert agronomist was used to define classes of risk defined in terms of their depth in metres below ground level. Combining information on the permeability of geological drift types further refined the assessment of the risk of crop growth vulnerability. The nature of the mapped output is one that is easy to communicate to the intended farming audience because of the general familiarity of mapped information. Such GIS-based products can play a significant role in the characterisation of catchments under the EU Water Framework Directive especially in the process of public liaison that is fundamental to the setting of priorities for management change. The creation of a baseline allows the impact of future increased water abstraction rates to be modelled and the vulnerability maps are a format that can be readily understood by the various stakeholders. This methodology can readily be extended to encompass additional data layers and for a range of groundwater vulnerability issues including water resources, ecological impacts, nitrate and phosphorus.

“…GIS can be useful for taking quick decisions as graphical representation would be easy to take a policy decision by the makers (Singh et al 2013b). GIS techniques have been becoming the most commonly used platform for assessment of groundwater vulnerability (Al-Adamat et al 2003;Becker 2006;Almasri 2008;Rahman 2008;Umar et al 2009;Saha and Alam 2014;Nasri et al 2015) along with the use of remote sensing techniques (Yeh et al 2006), statistical method (Burkart et al 1999;Fred et al 2002), environmental isotope and water chemistry method (Sadek and El-Samie 2001), and fuzzy mathematical method (Zhou et al 2010). The aim of the study is proper understanding of the aquifer system and hydro-geological setting of the area for development and safe exploitation of groundwater.…”

Groundwater vulnerability assessment could be defined as the degree of assimilation capacity of the area to the contaminant from surrounding surface above the aquifer. It has become an important element for sustainable natural resource management and proper landuse planning. This study aims at estimating shallow aquifer vulnerability by applying the GIS based DRASTIC model in Katri watershed, Dhanbad, Jharkhand. The probable groundwater quality decline due to various anthropogenic activities within the Katri watershed has necessitated this study using a combination of DRASTIC and GIS method as an effective method for groundwater pollution risk assessment. This model is based on the seven hydrogeological data layers that provide the input to the modelling. It corresponds to the initials of seven layers i.e. Depth of water, net Recharge, Aquifer media, Soil media, Topography, Impact of vadose zone and hydraulic Conductivity. The mapping of the DRASTIC index allows us to delineate zones with various degrees of pollution vulnerability. The study reveals that about 16.91 % of the watershed area is exposed to high-risk, 30.69 % exposed to medium-risk, and 52.4 % exposed to low risk. The south eastern and south western parts of the watershed are dominated by high vulnerability classes while the south, north western and lower middle portions are characterized by moderate vulnerability classes. The elevated northern, north eastern, and middle part of the study area displayed low aquifer vulnerability.
