The study was conducted to investigate the seasonal variation in water quality of the Padma River in order to assess the status of the river water quality. The Padma River is the main source of freshwater and fisheries resources to the southwest region of Bangladesh. The water samples were collected, during the period from April 2013 to March 2014,...
Agricultural activities cannot be separated from the use of agrochemical, both chemical fertilizer and pesticides. As the largest water user sector, agricultural activities are a source of water pollution. This study was carried out in Brantas’ upper stream along paddy fields, Karangploso Subdistrict, Malang District. The river water samples were c...
An attempt has been made to record the seasonal and diel variations in plankton production in relation to physico-chemical parameters and its impact on fisheries of river Narmada from Lamhetaghat to Bhedaghat near Jabalpur (Madhya Pradesh). Physico-chemical parameters like colour, odour, turbidity, temperature, pH, specific conductivity, total soli...
The current study focuses on seasonal variations in coastal water along the Bhavnagar coast, Gulf of Khambhat, Gujarat, India, during three consecutive seasons (pre–monsoon, monsoon, and post–monsoon). The coastal water samples were collected from seven different locations (Ghogha, Kuda, Mithivirdi, Sosiya, Alang, Sartanpar, and Gopnath). In the de...
Raw water quality for drinking water is a strategic issue requiring attention and environmental dynamics. River quality changes are crucial for sustainability and monitoring suitability. Kali Pelayaran, a tributary of the Brantas River, is a key source for drinking water in Sidoarjo Regency. The aim of the research is to analyze the water quality s...

... Observed EC of water samples ranged from 35.58 ± 3.0 to 38.82 ± 8.45µs/cm (S1) and 40.86 ± 7.54 to 44.31 ± 4.96µs/cm (S2). Higher EC values from S2 might be attributed to the high water temperature and subsequent evaporation (Pia et al., 2018). ...
Potholes are microhabitats in riverine ecosystems, which contribute substantially to the unique regional faunal diversity and community composition. The potholes of riverine habitats of Kerala are less explored, thus this study is of significant importance for riverine health assessment using entomological indicators. A total of 18 potholes were identified from the two stations located in the Chalakudy river basin according to their vertical profile. Insects were sampled monthly along with water quality parameters. We could identify 208 individuals represented by 15 families in the Athirappilly (S1). Among the collected taxa Ephemeroptera was the dominant order comprised of 48.56% of the population. Only 94 individuals represented by 10 families reported from the Ezhattumugham (S2). Hemiptera was the dominant order and comprised 51.06% of the total taxa collected. Benthic metrics such as family biotic index (FBI), % of Ephemeroptera Plecoptera, Trichoptera taxa (EPT), % of Ephemeroptera taxa, and % of tolerant organisms indicated remarkable variation in water quality status among the two stations and there was a significant difference in benthic metrics ( p < 0.05). Major functional feeding groups reported, the percentage contribution of predators (p = 0.010), shredders (p = 0.009), and scrappers (p = 0.007) exhibited statistically significant variations between stations. Insects belonging to the families of Baetidae, Ephemeridae, Perlidae, and Stenopsychidae were found to be the most sensitive forms reported from the S1 indicates good water quality condition. Contrastingly, insects belonging to the families of Micronectidae, and Chironomidae being pollution-tolerant taxa, were abundant at S2 indicates a fairly poor condition of the potholes.
... Phosphate has been considered as the main nutrients for the productivity of aquatic ecosystem. But if the quantity of phosphate gets much higher in the water body it speeds up eutrophication of the river and lake (Isratpia et al. 2018). During the present study, higher phosphate value was recorded during pre-monsoon (0.51±0.20 mg/L) while lowest in post-monsoon (0.16±0.02 mg/L) with average value 0.33±0.11mg/L. ...
... During the environmental sample analysis, we did not find significant inhibition to PCR amplification in our assay. However, for testing water from more contaminated sources, as determined by multivariate analysis of environmental factors where the industrial waste disposal and high population density matters [85,86], further treatment of the sample to remove inhibitors may be required. A study on water quality assessment of the roadside surface of Savar, Dhaka explained the impact of vehicle emission, atmospheric deposition from brick fields, industrial pollution and massive urbanization on the water reservoirs; total suspended solids (>25 mg/L), total dissolved solids (>840 mg/L), biological oxygen demands (0.758 mg/L) and dissolved oxygen (4.5 mg/L) were high or even higher than the standards [76]. ...
Cholera is a severe diarrheal disease caused by Vibrio cholerae, a natural inhabitant of brackish water. Effective control of cholera outbreaks depends on prompt detection of the pathogen from clinical specimens and tracking its source in the environment. Although the epidemiology of cholera is well studied, rapid detection of V. cholerae remains a challenge, and data on its abundance in environmental sources are limited. Here, we describe a sensitive molecular quantification assay by qPCR, which can be used on-site in low-resource settings on water without the need for DNA extraction. This newly optimized method exhibited 100% specificity for total V. cholerae as well as V. cholerae O1 and allowed detection of as few as three target CFU per reaction. The limit of detection is as low as 5 × 103 CFU/L of water after concentrating biomass from the sample. The ability to perform qPCR on water samples without DNA extraction, portable features of the equipment, stability of the reagents at 4 °C and user-friendly online software facilitate fast quantitative analysis of V. cholerae. These characteristics make this assay extremely useful for field research in resource-poor settings and could support continuous monitoring in cholera-endemic areas.
... In general, water sources come from surface water, groundwater and rainwater. The groundwater source consists of shallow groundwater and deep ground water (Panigrahy et al, 2015;Rahman andSabir, 2016 or Fitriati andSuryanur, 2017). The use of groundwater is one alternative that humans do to meet the needs of shallow water for household needs, as well as easy to obtain is also very economical (Behbananinia and Sarraf, 2015; Behbahaninia and Faharani, 2014;Djorfi et al, 2017). ...
Water has a very important role for human life. Water is a primary human need. In the past, water needs can be easily met from shallow groundwater sources, because it is thrifty and practical. The problem is in line with the development and the high population growth, soil water balance starts to be disrupted and the quality decreases. The study aims to see how big the use of shallow groundwater in the Banjarbaru Utara Sub district and then analyze it to determine the quality of the water. This research was conducted by direct field observation conducted by distributing questionnaires to the community. The results of this study found that the average shallow groundwater needs in Banjarbaru Utara Subdistrict amounted to 320 liters/person/day. While the annual requirement of 3,259,888 m 3 /year. Water quality is eligible for water that can be used as raw water for drinking water. Only the pH value is not eligible which is about 30.435%.
