“…The principal component analysis is one of the most widely used multivariate statistical tools utilized for the analysis of water quality parameters worldwide and also in the river Ganga (Bagla et al, 2021;Dimri et al, 2021b;Tyagi et al, 2020;Verma & Kumar, 2020). So for the present study, the PCA analysis was carried out.…”

“…A very strong negative correlation of EC was observed with fluoride (-0.92) while strong negative correlation with hardness (-0.75) and magnesium (-0.67). (2020).Total Dissolved Solids (TDS) is mainly due to the presence of ions/salts in water (Tyagi et al, 2020). TDS was found minimum at site 3 (475.0mg/l±13.49) and maximum was found at site 4 (507.8mg/l±9.09).…”

“…Water quality index (WQI) helps in understanding quality of water and therefore has been applied for the quality estimation of the water all over the world form the last few decades (Verma et al, 2018;Bhutiani et al, 2018;Adimallaa and Qian, 2019;Vaiphei et al, 2020;Bhutiani et al, 2021). Water quality is means of reflecting the quality of water in a single value (Sener et al, 2017;Tyagi et al, 2020). Various water quality calculation methods have been developed by several researchers and also by several countries.…”

Unplanned discarding of industrial effluent, sewage, domestic and industrial solid waste, unwise use of insecticides, herbicides, pesticides, and fertilizer in agriculture are the major causes of groundwater quality reduction. In the present paper groundwater quality of the two selected village of Rajauli subdivision of Nawada district of Bihar was assessed using water quality index (WQI). The samples were figured out for the parameters such as temperature, pH, electrical conductivity (EC), total dissolved solids (TDS), alkalinity, dissolved oxygen (DO), total hardness (TH), chloride, calcium (Ca), magnesium (Mg), biochemical oxygen demand (BOD), and fluoride. All the parameters were found below the standard limits of Bureau of Indian Standard (BIS, 2012) except total hardness (328.1mg/l to 346.6mg/l), calcium (105.3mg/l to 122.6mg/l), magnesium (46.1mg/l to 55.7mg/l) and fluoride (4.8 to 4.9mg/l). Fluoride was observed more than 3 times than the standard permissible limit (1.5mg/l). Water quality index (WQI) was also applied on the obtained data to make it easy to understand. Based on WQI (including the fluoride), all the four sites fall in unfit for drinking category (250.79, 258.78, 281.78, 247.30) and in poor to very poor category (80.23, 88.19, 88.59, 64.60) excluding the fluoride from WQI calculation. Both the values of WQI shows that fluoride alone is not responsible for the degraded quality of water but other high concentration of salts is also responsible.

“…In the present study, water samples were collected on a yearly basis from the Yamuna river canal in Dehradun, Uttarakhand, India. The samples were analyzed for 12 different physicochemical attributes like ph, BOD, COD, Total Coliform, Temp, DO, Alkalinity, Chlorides, Calcium, Magnesium, and Hardness as Calcium Carbonate, and TDS (Tyagi et al, 2020). The Yamuna river plays a very crucial role in Dehradun's geography.…”

The Yamuna river has become one of the most polluted rivers in India as well as in the world because of the high-density population growth and speedy industrialization. The Yamuna river is severely polluted and needs urgent revival. The Yamuna river in Dehradun is polluted due to exceptional tourist activity, poor sewage facilities, and insufficient wastewater management amenities. The measurement of the quality can be done by water quality assessment. In this study, the water quality index has been calculated for the Yamuna river at Dehradun using monthly measurements of 12 physicochemical parameters. Trend forecasting for river water pollution has been performed using different parameters for the years 2020–2024 at Dehradun. The study shows that the values of four parameters namely, Temperature, Total Coliform, TDS, and Hardness are increasing yearly, whereas the values of pH and DO are not rising heavily. The considered physicochemical parameters for the study are TDS, Chlorides, Alkalinity, DO, Temperature, COD, BOD, pH, Magnesium, Hardness, Total Coliform, and Calcium. As per the results and trend analysis, the value of total coliform, temperature, and hardness are rising year by year, which is a matter of concern. The values of the considered physicochemical parameters have been monitored using various monitoring stations installed by the Central Pollution Control Board (CPCB), India.
