“…similar to the current study Roopa and Gangadhar (2016) [35] recorded silicate concentrations ranging from 131.18 to 298.18 µg at/l while assessing the hydrological and nutrient status of the mangrove ecosystem of the Kali Estuary, Karwar, Karnataka, West coast of India. The range of the silicate concentration (µM) was observed to be between 21.35 to 316.84 µM such that the monsoon season observed the highest concentration of silicate, while the post-monsoon season recorded the lowest concentration (Santhanam et al, 2019) [36] .…”

Mangrove is a unique ecological environment and forms the habitat for a wide variety of marine organisms. The present study was carried out to investigate the water quality and nutrient dynamics in the selected mangroves of the Uttara Kannada district, Karnataka. The physico-chemical parameters of water were analyzed by standard methods. The study was conducted during the period from October 2021-September 2022. The physico-chemical properties showed significant seasonal variations at all the selected stations. The water quality parameters namely temperature,

“…Nutrients such as phosphate-P, silicate-Si, nitrite-N, nitrate-N and ammonia-N ranged between, 0.011 -1.258 ± 0.24 mg/l, 0.021 -1.82 mg/l ± 0.39, 0.0004 -0.103 ±0.01 mg/l, 0.002 -0.17 ±0.03 mg/l and 0.354 ±0.06 mg/l respectively. Maximum nitrate-N, nitrite-N, silicate-Si and ammonia-N concentrations observed during the monsoon season may be due to freshwater influx attributed to monsoonal rainfall into the system (Santhanam and Perumal, 2003). Nitrate-N (r = 0.411, p<0.05), nitrite-N (r = 0.766, p<0.01) and silicate-Si concentration (r = 0.778; p<0.01) were observed to be positively correlated with rainfall.…”

“…Matta et al ( 2020) observed a comparable range (9.9 to 23.0 0 C) of water temperature in the Ganga River, Uttarakhand. The lowest temperature is due to a strong breeze and its highest value is attributed to high solar radiation (Santhanam & Perumal 2003). The temperature of any river does not remain the same due to various environmental conditions (Kumari et al2013).…”

Different river bodies are diverse sustaining systems that provide freshwater to rapidly growing needs at the domestic, agricultural and industrial levels of the people of India. The river bodies need periodical examination for conservation and rejuvenation because they are currently under stress due to pollution and climate change. Arrah is a district of Bihar, India and occupies an area of 2395 km2 for agriculture as the predominant activity. It is an attempt to assess the water quality of River Ganga, Sone and Gangi in this area by combining the overall pollution index (OPI), comprehensive pollution index (CPI) and water quality index (WQI) from November 2021 to October 2023 from 648 water samples and nine sampling sites to establish a relationship between any change in water quality and their sources. We assessed eleven water quality parameters following standard methods for winter, summer and monsoon seasons. Observations showed that dissolved oxygen, total alkalinity, fluoride and rarely biochemical oxygen demand exceeded Bureau of Indian Standards (BIS 2012) prescribed limits and indicated deterioration in the water quality of these river bodies. Two-way ANOVA suggested that the water quality parameters of these river bodies showed significant differences (p<0.05). We used Numerical equations to transform the concentration values into pollution indices. Values of OPI (1.70 to 2.40) and CPI (0.65 to 0.90) indicate acceptable/ slightly polluted/moderately polluted water in these rivers. Values of WQI of these river bodies ranged from 182.0-192.1, 220.1-242.2 and 190.7-238.9 during winter, summer and monsoon seasons, indicating poor/very-poor water quality. The observation shows that the causes of the declining water quality in these water bodies are anthropogenic activity, agricultural waste runoff and entry of untreated sewage. To reduce the time-consuming and expensive water quality monitoring and assessment programmes for these river bodies, the water quality of these water bodies felt the need to adopt proper management policies and conservation efforts.
