Evaluation of Ground Water Contamination by Inorganic Pollutants in Tea Garden Area of Biswanath Chariali, Biswanath, Assam, India

Water stored underground is the nature’s blessing to the mankind. It is one of the Earth’s most precious resources and its development plays a vital role in the Country’s economy. The present investigation is a modest attempt to understand the potability of drinking water provided by different sources in the tea belt area of Biswanath Chariali, Biswanath, Assam. It has been observed that from the early point of the tea gardens a lot of pesticides and various types of chemical fertilizers have been used continuously. It is very likely that it may contaminate the ground water quality of the area by percolation, runoff and leaching process. Moreover due to lack of appropriate maintenance practice some source are observed in very worst condition and proper scientific study in this area is very scanty. Therefore, the evaluation of inorganic pollutants in groundwater in tea garden areas is a crucial for ensuring sustainable development and protecting human health. This study assesses the levels and sources of inorganic pollutants in groundwater sources within tea garden areas. A total of 10 numbers of water samples were collected from different water sources like ring wells, deep-tube wells and main supply plants of the gardens to study the different water quality parameters like pH, EC, TDS, TH, TA, Ca, Mg, free CO2, F-, Cl-, SO4 2-. Data were subjected to normal distribution pattern of the water quality parameters and correlation analysis was carried out to study the interrelationships between different parameters. The results revel concerning levels of levels of contamination. Agricultural activities, industrial operations and domestic waste are identified as significant sources of pollution. The study highlights the need for effective water management strategies, including regular monitoring, sustainable agricultural practices and proper waste management, to mitigate risks to human health.
