 Water pollution, one of the serious environmental issues of the world, results from contaminants being introduced into the natural environment. This study was conducted in the Microbiology laboratory, DAV College, Dhobighat, Lalitpur, Nepal from January to May 2018 with aims to assess the physicochemical and microbiological status of river water of Kathmandu valley. All together 60 water samples were collected, 20 water samples each from different places of Bagmati river, Bishnumati river and river junction (Teku Dovan). The physicochemical parameters including pH, ammonia and iron, hardness and alkalinity were analyzed by standard methods and the microbiological parameters such as total mesophilic count and total coliform count were analyzed by pour plate technique. Among all 60 water samples tested, the temperature (12.8°C), BOD value (3.11 mg/l), iron value (0.87 mg/l) and turbidity (102.2NTU) were found to be highest in Bagmati river water samples whereas the value of TSS (755.2 mg/l), TDS (748.4 mg/l), copper (0.01 mg/l) and COD (911.5 PPM) were found to be highest in water of Bishnumati river. The heavy meals Manganese (0.29 mg/l) and Nickel (0.01 mg/l) were detected only in Bishnumati river water samples. The river junction water samples showed the exceeded value of DO (9.56 mg/l) and chloride (0.12 mg/l). All the 60 samples showed total mesophilic counts more than 300 cfu/ml and the average number of total mesophilic counts were found to be 5.21×106 cfu/ml. The average number of total coliform counts were found to be 2.1×105 cfu/ml in the water samples of Bagmati river, Bishnumati river and river junction. Most of the tested parameter of the samples had more than the standard value of water quality indicating the deterioration of river water quality and thus may affect the aquatic as well as human and animal lives.

<p>Groundwater and Sutlej river water are major sources of irrigation in Rupnagar district of Punjab. Water quality was examined for their agricultural suitability using a total of 54 surface water (16 from Sutlej and 6 from Sirsa River) and groundwater (total 32 of ~160 m depth) samples from Pre- (June 2019) and post-monsoon (Dec 2018) seasons. On-site parameters (electrical conductivity, pH, total dissolved solids) indicate permissible pH (pH 6.6-8.2) and conductivity (147-1953 μS/cm), while 18.5% of samples are brackish salt to salt category type on salinity index. The results of these parameters were further interpreted and measured with different irrigation indexes like sodium percent (SP), sodium adsorption ratio (SAR), residual sodium carbonate (RSC), chloride concentrations and Wilcox diagram. Similarly, most of the samples (except Sutlej river water samples) were found to be above permissible limits with respect to SP (5.36-81.01) and RSC (0-6.23), but SAR is indicative of suitability for irrigation purposes (0.11-8.3). The suitability for irrigation as per SAR is because of low sodium content in all the samples relative to calcium and magnesium. The Wilcox diagram of pre-monsoon samples indicate high, medium and low saline to low sodium hazard except 1 sample with high saline to medium sodium hazard and salinity-sodium hazard in post-monsoon is comparatively lower than that of pre-monsoon. However careful observation of the complete data analysis suggests that all the parameters in Sutlej river water samples were found to be suitable for irrigation while most of the groundwater samples and 3 samples from Sirsa river were unfit for irrigation purposes as inferred from SP, RSC and Wilcox diagram.</p>

Thirty six dug well water samples from different houses along three transects and four Buriganga river water samples from four different Ghats (boat terminals) of the Old Dhaka of Bangladesh were collected during dry and wet periods for water quality assessment. The depth of these dug wells varies from 3.4 to 16 m with an average depth of 10 m with diurnal variations. The hydrochemical classification shows that the dug well and Buriganga river water samples are Ca-HC03 type. More than 50% dug well water samples were contaminated as concentration levels of Ca, K and Fe in both periods were high whereas over 25% Buriganga river water samples were tainted as concentration levels of Ca, Mg, Fe and Mn in dry season exceeded the drinking water quality standard limits of World Health Organization (WHO), Department of Environment (DOE) and United States Environmental Protection Agency (USEPA). If the dug well water is protected from contamination, the shallow groundwater in this part of Dhaka city should be an alternative perennial source of water especially during the dry season when water scarcity looms large Asiat.

Abstract Poor waste management in the Kathmandu valley has deteriorated the water quality of surface and groundwater sources. The objective of this study was to assess the status of water quality (WQ) in drinking water sources of groundwater and municipal supply (tap water) from the Bagmati river basin in Kathmandu valley. A total of 52 water samples from deep tube-well, tube-well, dug-well, and tap water were collected and analyzed for physical, chemical, and microbiological parameters using standard methods. The results revealed that chloride, total hardness (TH), copper, nitrate, sulfate, and turbidity were within the recommendations of the National Drinking Water Quality Standard (NDWQS). Total coliform (TC) bacteria in 84.6% of the samples exceeded drinking water guidelines. Similarly, the isolates of different enteric bacteria, namely Escherichia coli (21.5%), Citrobacter spp. (20.9%), Klebsiella spp. (19.8%), Proteus spp. (13.9%), Enterobacter spp. (8.72%), Salmonella spp. (5.8%), Shigella spp. (5.2%), and Pseudomonas (4.1%) were identified in the samples collected from the respective sources. Out of the 52 water samples, 7.7% of samples had fecal contamination of somatic coliphage. The groundwater and municipal water supply in the study area are not safe for drinking purposes. Treatment of water is required before its use for household applications.

Objectives: In order to evaluate the quality assurance of drinking water in Kathmandu valley, this study analyzed selected physiochemical and microbial parameters of treated water samples and compared with Nepal Drinking Water Quality Standards (NDWQS). Methods: Treated water samples were collected from all over the Kathmandu valley and analyzed in terms of physicochemical and microbiological parameters over the period of one year from July 2017 to July 2018. The physio-chemical parameters of water samples were performed according to standard methods for the examination of water and wastewater. The total coliforms were enumerated by standard membrane filtration technique. Results: We report that microbiological aspect of treated water was the major problem as 66% of the water samples crossed the guideline value for total coliform count. Above 92% of jar water samples, 77% of tanker water samples and 69% of filtered water samples had the total coliform count exceeding the NDWQS. Moreover, 20% of bottled water was contaminated by coliform bacteria. Iron and ammonia content were found to be higher than the guideline values in 16% and 21% of the total treated water samples respectively. Analyzing the types of treated water samples showed that 35% and 15% of tanker water samples had higher ammonia and iron content respectively, and the same parameters were higher in 23% and 19% in the filtered water samples respectively than the standard criteria recommended by NDWQS. Conclusion: The treated water samples exceed the standard values set by NDWQS and hence had poor quality. The presence of faecal pollution indicating coliform bacteria was the key problem for treated drinking water of Kathmandu valley. Therefore, monitoring and proper treatment of water should be conducted to prevent dissemination of waterborne diseases.

This research was conducted to analyze drinking water quality of Kathmandu valley. Total 969 water samples (392 from dug wells, 287 from deep boring, 218 from treated water, 46 from tap and 26 from other water sources) received from different places of Kathmandu, Lalitpur and Bhaktapur districts during March 2012 to March 2013. These samples were analyzed for the determination of physical (pH, temperature, conductivity, turbidity), chemical (hardness, chloride, iron, arsenic, ammonia, nitrate) and microbiological (total Coliform) parameters. It was found that the temperature and nitrate were within the WHO standards while pH, conductivity, turbidity, chloride, iron, arsenic, ammonia, and Coliform bacteria exceeded the WHO standard guideline. In ground water ( well and Boring), pH, conductivity, hardness, turbidity, iron, arsenic, chloride, ammonia and total Coliform count crossed WHO standards as 5%, 2%, 0.8%, 36%, 51%, 0.1%, 2%, 11% and 86 % respectively. Hardness was within the standard in both  reated and tap water samples. Compared to treated water, pH, arsenic and chloride were within the standard in tap water. The common problematic parameters of different sources of drinking were turbidity, iron, ammonia and conductivity. Coliform bacteria were found in 36% samples of treated water whereas 80% tap water samples were contaminated from Coliform bacteria.DOI: http://dx.doi.org/10.3126/njst.v15i1.12027Nepal Journal of Science and TechnologyVol. 15, No.1 (2014) 115-120

Objectives: The aim of this study was to assess quality status of ground water in Kathmandu valley and describe the antibiotic susceptibility of the isolated Klebsiella pneumoniae. Methods: A total of 100 samples were collected from different places of Kathmandu valley with 50 each from two different groundwater sources namely boring and well. This study was conducted from June to September, 2019 at Environment and Climate Study Laboratory, Nepal Academy of Science and Technology (NAST). The physicochemical analysis of the samples was done according to standard methodology. Membrane filtration technique was performed for the enumeration of total coliform and different biochemical tests were performed for isolation and identification of Klebsiella pneumoniae followed by Kirby-Bauer disc diffusion method for antibiotic susceptibility test. Results: This study reveals the poor microbiological aspects of ground water sources as 98% of total water samples crossed the standard value for total coliform count. The pH, turbidity, ammonia, nitrate and iron content were found to be higher than Nepal Drinking Water Quality Standard (NDWQS 2005) in 15%, 26%, 34%, 7% and 26% of total water samples respectively. The chloride and arsenic content in all the water samples were within the NDWQS, 2005. The 12 out of 18 isolates of Klebsiella pneumoniae from ground water source were highly resistant against first generation Cefazolin however, 15 out of 18 isolates were sensitive to Chloramphenicol. Additionally, four isolates showed zone of inhibition in intermediate range provided by Clinical and Laboratory Standard Institute (CLSI) guideline towards Imipenem and Meropenem. Conclusion: This study concludes that ground water sources were heavily contaminated by coliform bacteria and most of the physicochemical aspects were under standard limit. Although Klebsiella pneumoniae isolated from ground water were not multidrug resistant, one isolate was recorded to be resistant to Meropenem. These results alarm for circulation of antibiotic resistance in environmental bacterial isolates. Therefore, the appropriate water purification methods should be applied before consumption and should be examined periodically.

Water is important for survival of living beings as well as geological and geomorphic processes on the planet Earth. In the present scenario of developmental activities both surface and groundwater are polluted and need attention for checking the pollutant sources. Ghaggar river in northern part of the country is flowing from the states-Himachal Pradesh, Haryana, Punjab, Rajasthan and finally in Pakistan. In the upper part of the Ghaggar river after entering in Haryana in Panchkula district its water quality has been assessed for drinking purpose. Eight river water samples were collected from different locations of Ghaggar River in the month of June 2019. Water samples were analyzed using Field Water Testing Kit prepared by Tamilnadu Water Supply and Drainage Board (TWAD), Chennai for chemical parameters-pH, Hardness, Chloride, Fluoride, Iron, Ammonia, Nitrite, Nitrate, Phosphate and Residual Chlorine. Results of chemical analysis of water samples were categories as per BIS drinking water standards (IS 10500:2012). In the river water samples pH ranges from 6.5 to 7.5; hardness ranges from 100 mg/l to 1170 mg/l; chloride ranges from 50 mg/l to 360 mg/l; fluoride ranges from 0.5 mg/l to 3 mg/l; iron ranges from nil to 10 mg/l; aammonia ranges from 0.5 mg/l to 5 mg/l; nitrite ranges from 0.2 mg/l to 1 mg/l; nitrate ranges from 20 mg/l to 150 mg/l; phosphate ranges from 0.5 mg/l to 1 mg/l and residual chlorine ranges from nil to 2 mg/l. The data interpretation shows that pH in all the eight water samples is desirable for drinking purpose; hardness is desirable at Bitna, Kaushalya Dam, MajriChowk, Peer Muchchalla, Sector28, Panchkula, Daffarpur and permissible at Jagatpur and non-potable at ChandiMandir; chloride is desirable at Bitna, Jagatpur, Kaushalya Dam, MajriChowk, Peer Muchchalla, Sector-28, Panchkula, Daffarpur and permissible at ChandiMandir; fluoride is desirable at Bitna, Jagatpur, Kaushalya Dam, MajriChowk, Peer Muchchalla, Sector-28, Panchkula, Daffarpur and non-potable at ChandiMandir; iron is desirable at Bitna, Kaushalya Dam, Peer Muchchalla, Sector-28, Panchkula, Daffarpur and non-potable at Jagatpur, ChandiMandir, MajriChowk; ammonia is desirable at Bitna, Sector-28, Panchkula, Daffarpur and non-potable at Jagatpur, Kaushalya Dam, ChandiMandir, MajriChowk, Peer Muchchalla; nitrite is desirable in all the eight water samples; nitrate is desiarble at ChandiMandir, MajriChowk, Peer Muchchalla, Sector-28, Panchkula and non-potable at Bitna, Jagatpur, Kaushalya Dam, Daffarpur; phosphate is desirable in all the eight water samples and residual chlorine is desirable at Bitna, Jagatpur, Kaushalya Dam, ChandiMandir, Peer Muchchalla, Sector-28, Panchkula, Daffarpur and non-potable at MajriChowk. The study shows that river water is not suitable for drinking purpose in seven water samples except one water sample (Sector-28, Panchkula). The study is highly useful for monitoring the water quality of Ghaggar River.

Water quality parameterization is a great concern because chemical contaminants and microbiological impurities including pathogenic bacteria may pose a health risk and unfit for its domestic use. Alkalinity, pH, conductivity, chlorine demand, turbidity, and ammonia were measured to characterize the water quality of the Bagmati River. The effect of tributaries on Bagmati River was determined by sampling water from five different sites such as Pashupati (B-1), Shankhamul (B-2), Kupondol (B-1), Balkhu (B-4), and Jalbinayek (B-5) sites. The water samples B-2, B-3, B-4 and B-5 were less turbid but black in color while water sample B-1 was more turbid but grey in color. The pH of water samples ranged from 6.7 to 7.3. The alkalinity, conductivity and chlorine demand were 60 ppm, 95.7 µs and, 5.44 ppm, respectively for B-1 sample and increased almost continuously from B-2 to B-5 sample. The alkalinity was 360 ppm, conductivity was 862 µs and chlorine demand was 23.7 ppm for the last sample (B-5). The concentration of ammonia in the B-1 sample was only 0.0625 ppm whereas it was 3.32 ppm in the B-5 sample. The enhancement of chlorine demand and concentration of ammonia attributed that tributary and local effluent loaded extremely high levels of pollutants into the Bagmati River which might include pathogenic microorganisms. The random chance of some parameters like pH, conductivity, ammonia, turbidity along the Bagmati River indicates the impacts of different tributaries on Bagmati River. The chorine demand showed a positive correlation with conductivity, alkalinity and ammonia while the negative correlation with turbidity. This revealed that the conductive alkaline pollutants consumed more chlorine than colloidal particles. From the study it is considered that the Bagmati River water contains natural as well as anthropogenic pollutants which is extremely hazardous not only to the people using river water but also for the living organism rely on the river.
