本研究调查了印度泰米尔纳德邦Tirunelveli和Thoothukudi沿海地区钻孔水的污染脆弱性。Tirunelveli沿海地区没有工业，而泰米尔纳德邦国家工业促进公司（SIPCOT）和Thoothukudi沿海地区有许多工业。本研究于2006年7月至2008年5月定期收集sipott、Thoothukudi和Tirunelveli沿海地区的钻孔水。对这些样品进行了测试和分析，以确定钠、镁、铝、钾、钙、铜、镉、汞和铅的浓度。2007年11月在SIPCOT 2中发现镉的有毒浓度为0.00-0.22 mg Kg(-1)， 2008年1月在SIPCOT 2中发现汞的有毒浓度为0.00-0.024 mg Kg(-1)，铅的有毒浓度为0.00-0.02 mg Kg（-1）。污染程度高于世卫组织饮用水标准的限制；但铜和铝的含量在限制范围内。另一方面，从Tirunelveli沿海地区的钻孔中采集的样本没有受到污染，分析表明所有金属都在世界卫生组织的标准范围内。
This study investigates the pollution vulnerability of bore water in the coastal region of Tirunelveli and Thoothukudi in the state of Tamilnadu, India. There are no industries in the Tirunelveli Coastal area whereas there are many industries in SIPCOT (State Industries Promotion Corporation of Tamilnadu) Thoothukudi, and coastal area of Thoothukudi. Bore water from the SIPCOT, coastal area of Thoothukudi and Tirunelveli were collected periodically from July 2006 to May 2008 for this study. These samples were tested and analyzed to find the concentrations of sodium, magnesium, aluminium, potassium, calcium, copper, cadmium, mercury and lead. The toxic cadmium concentration was found in the range of 0.00-0.22 mg Kg(-1) at SIPCOT 2 in November 2007, mercury 0.00-0.024 mg Kg(-1) and lead 0.00-0.02 mg Kg(-1) in SIPCOT 2 in January 2008. The level of contamination is higher than the WHO limits of drinking water standards; but copper and aluminium content are within the limit. On the other hand, the samples taken from bores in Tirunelveli coastal area are non-polluted, and the analysis shows that all the metals are within the limits of WHO standard.
