“…Nevertheless, besides the high variability, by the end of 2012/2013 the levels were lower compared with the previous years, except for the Basin of Alvalade aquifer. The concentration of total phosphorus in groundwater is not related to the geology, due to the scarcity of this compound in igneous and metamorphic rocks, requiring other sources, including anthropogenic activities and degradation of organic matter (Menezes et al 2014). The high value detected during the hydrological year of 2012/2013 was observed at a dry land crop field and perhaps it was a particular situation.…”

Influence of different land uses on groundwater quality in southern Portugal

In Alentejo region, southern Portugal, differences in groundwater samples from six groundwater bodies covered with different land uses were analysed based on the monitoring plan of the Alqueva multi-purpose project, created in the sequence of the construction of the Alqueva Dam on the Guadiana River, in South Portugal. For most of the groundwater bodies there is a statistical significant difference between magnesium, sulphate, chloride, and phosphate. All of these ions are strongly correlated with land use management. Groundwater, where land is covered by olive groves, has high levels of electric conductivity, calcium, potassium, sulphate, and phosphate. Dry land crops are correlated with calcium, magnesium, chloride and consequently, electric conductivity, phosphates and sulphate. Vineyards are strongly correlated with high sulphate and phosphate levels. This study clearly shows that different land uses within a certain groundwater body influence the water quality in a different way. Therefore, an appropriate soil management should be adjusted to each situation, taking into account the aquifer matrix and the overlying soil.

“…Several factors influence water quality of a watershed, such as rainfall, vegetation cover, topography, geology, as well as the type, use, and management of the soil located in the river basin (MARQUES, 2016;VERONEZ, 2011); UNESCO, 1998). Contamination of the underground springs is due to a series of factors related to the disorderly growth of the cities, inadequate disposition of residues, lack of sanitary sewage systems, and the lack of urban planning (MENEZES, 2014;LAZZERINI, 2013;LOBLER, 2013;CUNHA;SHIRAIWA, 2011, MERTEN, 2002.…”

“…In addition to increasing the consumption of groundwater, population growth tends to increase groundwater pollution. The expansion of human activities modifies groundwater quality and availability (HOWARD, 2002;MENEZES et al, 2014;COSTA et al, 2015a;MENG et al, 2015).…”

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.
