In the present study, twenty water samples were collected during pre-monsoon (June 2017) and post-monsoon (December 2017) seasons. The water samples were analyzed to determine various chemical parameters like chloride, fluoride, sulphate, nitrate, phosphate. During pre-monsoon (PRM) and post-monsoon (POM) the order of dominance of anion in the water samples are HCO3> TDS > Cl> SO42−> TH > NO3> F> PO4 and TDS >HCO3>SO42−>Cl> TH >NO3>F>PO4, respectively. The order of dominance of cations are Na+> Ca2+> Mg2+> K+ in both the seasons. The irrigation water quality was determined using the parameters such as sodium absorption ratio (SAR), Kelly’s ratio (KR), residual sodium carbonate (RSC), potential salinity (PS), permeability index (PI), sodium percentage (SP), magnesium hazard, calcium to magnesium molar ratio. The groundwater’s geochemical control and hydrogeochemistry were evaluated using the Piper, Chadha, scatter and Gibbs plots. This study reveals that groundwater quality is unfit for drinking purposes at a few places in the study area.

利用统计方法和GIS技术评估印度泰米尔纳德邦维鲁德纳加尔·塔鲁克(Virudhunagar Taluk)的地下水质量

在本研究中,在季风前(2017年6月)和季风后(2017年12月)季节收集了20个水样。分析水样以确定各种化学参数,例如氯化物,氟化物,硫酸盐,硝酸盐,磷酸盐。在季风前(PRM)和季风后(POM)期间,水样中阴离子的优势顺序为HCO 3 > TDS> Cl > SO 4 2− > TH> NO 3 > F> PO 4 TDS> HCO 3 > SO 4 2− > Cl > TH> NO 3 > F > PO 4 , 分别。在两个季节中,阳离子的主导顺序为Na + > Ca 2+ > Mg 2+ > K +。使用钠吸收率(SAR),凯利比(KR),残留碳酸钠(RSC),势盐度(PS),渗透率指数(PI),钠百分比(SP),镁等参数确定灌溉水的质量危害,钙镁摩尔比。使用Piper,Chadha,散布图和Gibbs图评估了地下水的地球化学控制和水文地球化学。这项研究表明,在研究区域的某些地方,地下水水质不适合饮用。
