摘要
背景:水是生命的灵丹妙药,是一种主要的自然资源。由于印度的快速城市化,地下水的可用性和质量受到了影响。据中央地下水委员会称,金奈80%的地下水已经枯竭,任何进一步的勘探都可能导致盐水入侵。因此,本研究对金奈市地下水水质进行了评价。目的:利用水质指标对金奈市地下水水质进行评价。材料与方法:将金奈市按立法选区划分为3个区,在3个区中随机选取3个地点,采集9份地下水样本进行理化性质分析。结果:除少数参数外,大部分水质评价参数均在印度标准局(Bureau of Indian Standards, BIS)认可标准值范围内。除第1区某一地点的pH值外,其他参数均未超过BIS规定的水质评估允许值。结论:综合水质指标和氟化物含量9项指标,研究表明金奈市地下水水质状况总体为优至良,适合人类饮用。
An assessment of groundwater quality using water quality index in Chennai, Tamil Nadu, India
Context : Water, the elixir of life, is a prime natural resource. Due to rapid urbanization in India, the availability and quality of groundwater have been affected. According to the Central Groundwater Board, 80% of Chennai's groundwater has been depleted and any further exploration could lead to salt water ingression. Hence, this study was done to assess the groundwater quality in Chennai city. Aim : To assess the groundwater quality using water quality index in Chennai city. Materials and Methods: Chennai city was divided into three zones based on the legislative constituency and from these three zones three locations were randomly selected and nine groundwater samples were collected and analyzed for physiochemical properties. Results: With the exception of few parameters, most of the water quality assessment parameters showed parameters within the accepted standard values of Bureau of Indian Standards (BIS). Except for pH in a single location of zone 1, none of the parameters exceeded the permissible values for water quality assessment as prescribed by the BIS. Conclusion: This study demonstrated that in general the groundwater quality status of Chennai city ranged from excellent to good and the groundwater is fit for human consumption based on all the nine parameters of water quality index and fluoride content.
