Hydrochemical characteristics and quality assessment of groundwater along the Manavalakurichi coast, Tamil Nadu, India

Abstract

The present study was carried out to find the groundwater quality of coastal aquifer along Manavalakurichi coast. For this study, a total of 30 groundwater samples were collected randomly from open wells and borewells. The concentration of major ions and other geochemical parameters in the groundwater were analyzed in the laboratory by adopting standard procedures suggested by the American Public Health Association. The order of the dominant cations in the study area was found to be Na ? [ Ca 2? [ Mg 2? [ K ? , whereas the sequence of dominant anions was Cl À [ HCO À 3 [ SO 2À 4. The hydrogeochemical facies of the groundwater samples were studied by constructing piper trilinear diagram which revealed the evidence of saltwater intrusion into the study area. The obtained geochemical parameters were compared with the standard permissible limits suggested by the World Health Organization and Indian Standard Institution to determine the drinking water quality in the study area. The analysis suggests that the groundwater from the wells W25 and W26 is unsuitable for drinking. The suitability of groundwater for irrigation was studied by calculating percent sodium, sodium absorption ratio and residual sodium carbonate values. The Wilcox and USSL plots were also prepared. It was found that the groundwater from the stations W1, W25 and W26 is unfit for irrigation. The Gibbs plots were also sketched to study the mechanisms controlling the geochemical composition of groundwater in the study area.

Hydrogeochemical investigation of groundwater in shallow coastal aquifer of Khulna District, Bangladesh

“…Seawater intrusion is a major threat in the coastal aquifers of Bangladesh, especially in southwestern region (Bahar and Reza 2010;Islam et al , 2016bIslam and Bhuiyan 2016). The over dependence on groundwater for drinking, agricultural and industrial sector and different climatic and natural phenomenon causes coastal groundwater contamination (Srinivas et al 2015). Besides, different geochemical processes in groundwater governing the chemical characteristics of groundwater, is well documented in many parts of the world by many authors i.e., Montety et al (2008), Jalali (2009), Manjusree et al (2009), Thilagavathi et al (2012, Sivasubramanian et al (2013), Nagaraju et al (2014), Kumar et al (2015), Islam et al (2016a, b) and Balaji et al (2016).…”

Study of the Hydro-Chemical and Bacteriological Well Water Characteristics of M’Bahiakro (Central-Eastern Côte d’Ivoire)

“…A first approach uses hydrochemical water classification based on major physico-chemical variables, carried out under Piper and Schöeller-Berkaloff using the DIAGRAMMES 2.0 software. These diagrams are very commonly used in the field of water hydrochemistry, with very good results in Pakistan, Ivory Coast, Ghana and India by authors such as (Eblin et al, 2014;Oga et al, 2010;Bashir et al, 2017;Salifu et al, 2017;Srinivas et al, 2017). Indeed, these representations, which have the disadvantage of representing the major elements of well water in the form of percentages and milligrams per litre respectively, allow us to have an overall view of the chemical content of our water samples and to identify any changes.…”

Application of Traditional Method and Water Quality Index to Assess Suitability of Groundwater Quality for Drinking and Irrigation Purposes in South-Western Region of Libya

“…Assessment of groundwater quality index with respect to different uses has been carried out by several researchers around the world and can be found in recent numerous publications such as: [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29].…”
