“…Groundwater is an important renewable natural resource required for our day-to-day life. Agricultural usage consumes about 70% of the total available groundwater, while the remaining is being used in industrial activities and domestic needs such as drinking and sanitation (Ayoob & Gupta, 2006;Kumar et al, 2018). The availability of groundwater for drinking purposes is steadily decreasing, especially in developing countries such as India, Sri Lanka, China, and Pakistan (Ayoob & Gupta, 2006).…”

The availability and quality of groundwater for drinking purpose is steadily decreasing due to influx of contaminants and high rate of extraction. Fluoride contamination in groundwater is posing serious threat to human health, being a reason of dental and skeletal fluorosis. The present study is aimed to assess the current status of fluoride in groundwater resources of Lucknow, Uttar Pradesh, India, and geoclassify the location on the scale of fluorosis threat. The study was conducted in eight blocks of Lucknow, targeting 190 spots. 82.11% of groundwater samples were found within the permissible limit, while 17.89% samples revealed fluoride concentration higher than the permissible limit (1.5 mg/L) prescribed by WHO in 2011. It was observed that around 81.47% population of Sarojininagar, 62.51% population of Kakori, 43.03% population of Mohanlalganj, 6.16% population of Gosaiganj, and 5.47% population of Chinhat are currently exposed to high fluoride concentration (> 1.5 mg/L) and prone to risk of adverse health effect posed by excess fluoride consumption. If the current scenario continues, the proportion of population vulnerable to fluoride toxicity may increase in the future.

“…Higher TDS and salinity during pre-monsoon are results of high evaporation rates of water. Electrical conductivity (EC) depends on temperature, salinity, and TDS of water [49,50]. Higher EC during pre-monsoon is associated with high temperature and high evaporation rates of water.…”

This study has evaluated the potential ecological risk and human health risk for the contamination of nine elements (Cu, Cr, Mn, Zn, As, Pb, Co, Fe, and Sr) in water and sediment samples in two seasons, i.e., before and after rainy season, by calculating several pollution indices such as pollution load index (PLI), potential ecological risk (PER), and target hazard quotient (THQ). Samples were analyzed for elemental concentration using energy dispersive X-ray fluorescence (EDXRF) spectrometry. This study found that waters in the Kutubdia channel are safe and standard for aquatic organisms. In addition, the study area’s elemental concentration in water and sediments is still safe but moderately enriched with Zn and Cu. The elemental concentration in water was observed to be high in the pre-monsoon season and vice versa in the sediment study. The result also reveals no potential ecological risk (PER < 4) in the study site. However, the health risk index showed a noncarcinogenic risk (THQ > 1) for children and adults regarding the inhalation process where manganese was dominant. Apart from this, the pollution source was also identified by multivariate statistical analysis, including cluster analysis (CA) and principal component analysis (PCA)–and a natural pollution source prevalent was found.

“…The most important and largest storage of groundwater is drinkable for the human populace . Regularly, around 33% of the human population is utilizing groundwater for drinking purposes. − In India, around 60% of the groundwater is used for irrigation requirements, and 85% of the groundwater is used for drinking and domestic requirements . Recently, in the coastal areas, groundwater utilization has increased to meet the water demand for industrial and irrigation uses .…”

A Case Study of the Effect of Seawater Intrusion on the Water Quality Index of the Indian Southeastern Coastal Region

Safe and clean acceptable quality of water is essential for the survival of life. There are severe problems with the insufficient availability of safe groundwater for human consumption. The present study aims to evaluate the groundwater quality in the coastal area of Srikakulam district, located in the extreme northeastern direction of Andhra Pradesh in India. The study area spreads over an area of 130 km 2 . In this study, groundwater is the major source for drinking and irrigation purposes. A total of 20 bore well (BW) groundwater samples were collected with a distance of 5 km each during the period of the premonsoon and monsoon seasons of 2020. This study investigates the importance of groundwater quality in some areas of the coastal villages in the Srikakulam district. The overall water quality condition is explained with various physicochemical parameters such as pH, electrical conductivity (EC), total dissolved solids (TDS), total hardness (TH), total alkalinity (TA), calcium (Ca 2+ ), magnesium (Mg 2+ ), fluoride (F − ), chloride (Cl − ), nitrate (NO 3 − ), sulfate (SO 4 2−), sodium (Na + ), potassium (K + ), and turbidity. The water quality is assessed on the basis of the water quality index (WQI) method. The physicochemical results are compared to the water quality standards of the World Health Organization (WHO), 2012, and the Bureau of Indian Standards (BIS), 2012. The correlations between the values have been presented for various parameters. The water quality index (WQI) ranged between 11.56 and 61.27, the highest value recorded at M. Ganguwada and the lowest at Bandaravanipeta. The analytical results showed that around 90% of the samples are extremely hard in their nature and that their Na + and Cl − concentrations are also higher. It indicates that the coastal region is influenced by seawater intrusion.
