“…The soil permeability is affected by long-term usage of water for irrigation and other purposes. Based on the permeability index in the study area, 90 % of the samples were suitable for irrigation and 10 % of the samples were unsuitable according to the Doneen (1964) water suitability classification for irrigation purpose.…”

A total of 20 groundwater samples were collected from both dug and bore wells of southern Tiruchirappalli district and analyzed for various hydrogeochemical parameters. The analyzed physicochemical parameters such as pH, electrical conductivity, total dissolved solids, calcium, magnesium, sodium, potassium, bicarbonate, carbonate, sulfate, chloride, nitrate, and fluoride are used to characterize the groundwater quality and its suitability for drinking and irrigational uses. The results of the chemical analysis indicates that the groundwater in the study area is slightly alkaline and mainly contains Na ? , Ca 2? , and Mg 2? cations as well as HCO 3 2-, Cl -, SO 4 2-and NO 3 -anions. The total dissolved solids mainly depend on the concentration of major ions such as Ca, Mg, Na, K, HCO 3 , Cl, and SO 4 . Based on TDS, 55 % of the samples are suitable for drinking and rest of the samples are unsuitable for drinking. The total hardness indicates that majority of the groundwater samples are found within the permissible limit of WHO. The dominant hydrochemical facies for groundwater are Ca-Mg-Cl, Ca-HCO 3 , and Ca-Cl type. The USSL graphical geochemical representation of groundwater quality suggests that majority of the water samples belongs to high medium salinity with low alkali hazards. The Gibb's plot indicates that the groundwater chemistry of the study area is mainly controlled by evaporation and rock-water interaction. Spearman's correlation and factor analysis were used to distinguish the statistical relation between different ions and contamination source in the study area.

“…Do total das amostras analisadas no banco de dados (cerca de 1.150) foram excluídas aquelas que não obedeciam aos testes de consistência sugeridos por Richards (1954), Arar (1972) e Doneen (1975) que sugerem comparar a proximidade da diferença entre a soma de cátions, a soma de ânions e correlações clássicas entre os íons sódio e cálcio em relação à condutividade elétrica. Água com variações além das permitidas, sugeridas pelos autores supra citados, era excluída do banco de dados (Brasil, 1979).…”

Mossoró. As análises fisico-químicas permitiram avaliar a qualidade da água para irrigação, empregando-se índices clássicos da literatura, como Índice de Saturação de Langelier, CE, RAS, RAS aj e RAS cor . Na maioria das amostras estudadas observou-se que mais de 30% apresentam problemas devido ao risco de sodicidade (RAS elevada). A maior incidência de água com problemas de salinidade (elevada CE) e sódio ocorreu naquela proveniente de poços tubulares, que captam água de calcário ou aquíferos abastecidos diretamente pelo lençol freático. Dependendo do modo como se calculou a RAS, algumas amostras de água mudaram de classe, quando se empregou o ábaco desenvolvido pelo Laboratório de Salinidade dos Estados Unidos (USSL).Palavras-chave: água, fisico-química, irrigação, razão de adsorção de sódio QUALITY OF THE WATER FOR IRRIGATION IN DIFFERENT AQUIFERS IN AREA OF SEDIMENTS IN THE RIO GRANDE DO NORTE STATE, BRAZIL ABSTRACTMore than 600 water samples from different aquifers in a semi-arid region of northeastern of Brazil were studied. The analyses were conducted using a database of the Laboratory of Analysis of Water and Soil Fertility of the Department of Soils and Geology of Escola Superior de Agricultura de Mossoró. The analyses of physical and chemical properties allowed the evaluation of the quality of the water for irrigation using classic indexes in literature such as Index of Saturation of Langelier (ISL), Sodium Adsorption Ratio (SAR), SAR adjusted (SARaj) and corrected SAR (SARcor). A large number of water samples presented salinity problems and high amounts of sodium in relation to the bivalent cations Ca and Mg. The largest incidence of water with salinity and sodium problems belonged to tubular wells. Depending on the way the SAR was calculated, some water samples shifted class when the abacus developed by United States Salinity Laboratory was used.

“…Debido a que el agua es uno de los factores limitantes para la producción en algunas áreas de cultivo, en México se utiliza el agua residual para el riego agrícola (Velázquez et al, 2002), por esta razón es importante evaluar su calidad agronómica, en este sentido, Eaton (1950) consideró necesario evaluar el riesgo de salinización del suelo por la aplicación del agua al riego agrícola, por su parte, Doneen (1975) indicó que la calidad del agua se determina por la concentración y tipo de constituyentes disueltos que contenga, al respecto, Ayers y Westcot (1987) coincidieron en que dependerá de su composición iónica y de algunos índices de salinidad. En relación con la calidad del agua para riego agrícola Richards et al (1954) propusieron evaluarla de acuerdo con la CE y la RAS, como indicadores de riesgo de salinidad y sodicidad.…”

“…En este mismo sentido, Doneen (1975) propuso estimar los índices de salinidad efectiva (SE) y potencial (SP) en las aguas de riego, ya que la alta concentración de sales afecta la disponibilidad de agua para los cultivos, por su parte, Eaton (1950) propuso el índice de carbonato de sodio residual (CSR) para estimar la precipitación de carbonato y bicarbonato de Ca 2+ y Mg 2+ . En esta investigación, de acuerdo con los resultados de SE, SP y CSR, no se recomienda la aplicación del agua al riego agrícola.…”

RESUMENEn este estudio se recolectaron muestras de agua en el efluente de una planta de tratamiento de agua residual durante los meses de enero a julio de 2012. El objetivo fue determinar la concentración de metales pesados, así como evaluar la calidad agrícola del agua residual tratada. Los resultados del análisis de los elementos: cadmio (Cd), cobre (Cu), cromo (Cr), níquel (Ni), plomo (Pb) y zinc (Zn), muestran que la concentración de estos metales fue baja, por lo que, de acuerdo con la NOM-001-SEMARNAT-1996 el agua residual tratada cumple con la concentración permitida para su descarga en cuerpos receptores. Mediante las variables Ca 2+ , Mg 2+ , Na + , K + , CO 3 2-, HCO 3 -, Cl -, SO 4 2-, pH, conductividad eléctrica (CE) y relación de adsorción de sodio (RAS) se determinó su calidad agrícola. Los indicadores de salinidad muestran que el agua no es adecuada para la irrigación. Los valores de RAS fueron menores de 5,5 meq L -1 , y los valores conjuntos CE-RAS sugieren la clasificación del agua como C4-S1, lo que indica que el agua tiene restricciones de uso por el riesgo de salinidad al aplicarla al riego agrícola.Palabras clave: salinidad, sodicidad, irrigación.
