Sylhet City Corporation (SCC) of Bangladesh is supplying water to the Sylhet city dwellers through its distribution network. The quality of water is at risk to deteriorate during its flow through the distribution system and also due to probability of high elemental concentrations in groundwater. To identify such probable water contamination problems; water samples from 20 (out of 27) different wards of the city were analyzed in this study. The parameters analyzed were pH, turbidity, total alkalinity as Calcium carbonate CaCO3, total hardness, iron, manganese, arsenic, chloride, fluoride, MPN (Most Probable Number), total viable count (TVC), coliform and fecal coliform. The study revealed that all the physico-chemical parameters except alkalinity were in the permissible limit. All the samples were found to have total alkalinity as CaCO3 value higher than the WHO and Bangladesh Standards limit. But the water from treatment plant was found to have high turbidity and iron concentration. Analysis of microbial water quality parameters revealed that there was no coliform and fecal coliform contamination. But high value of MPN index and total viable count indicates that there were obvious contamination and chances of contamination by non-fecal pathogens. Finally, it is concluded and recommended that the water treatment facilities of SCC have to be improved, further investigation should be done to identify the non-fecal organisms and the cause of high total viable bacteria should be detected and corrected for the betterment of the city dwellers.

The city of Purwokerto is crossed by several large rivers, this research examines several tributaries of a large river. Some tributaries that pass through the city of Purwokerto are the Raden River, the Caban River, the Jurig River and the Luhur River. Tributaries have the potential to influence water quality. This study aimed to analyze the quantity of coliform bacteria as an indicator of water pollution in several tributaries in Purwokerto City, Banyumas Regency. Microbiological tests were carried out by calculating the total coliform quantity and fecal coliform using the Most Probable Number (MPN) test. Total coliform and fecal coliform can be used as a reference indicator of water quality in the presence of water pollution. The laboratory test results for the quantity of coliform bacteria showed in several tributaries in Purwokerto City, Banyumas Regency, very high in total coliform or fecal coliform, exceeding the water quality standard.

Coliform is a group of microbes that are used as indicators of water quality. Water pollution is generally caused by pathogenic microbes from feces, household waste, and industrial activity waste. This study aimed to estimate the total number of coliform contamination in several rivers in Kepahiang Regency, namely Tebat Monok (TM), Sempiyang (SPY), Penanjung Panjang (PP), Embong Ijok (EI) Air Langkap(ALK), and Air Belimbing (ABB).  Total coliform and Fecal coliform tests were carried out using the Most Probable Number (MPN) method on Lactose Broth, Brillian Green Lactose Bile Broth and pour plates on Eosin Methylene Blue Agar media. Measurement of abiotic factors was on temperature and pH parameters. The test results of total coliform showed that 6 rivers contained total coliform under the Class II river water quality standards with a range of 1210/100 mL– 4310/100 mL and 2 rivers that were contaminated with Fecal coliform, TM and ALK, have the content of 1500/100 mL and 1700 / 100 mL. The results of the measurement of the abiotic factor, the river pH range was 7.4 - 8.2. The lowest temperature was 25oC in SPY river and the highest temperature was 26 oC on the TM, PP, EI, ALK, and ABB rivers.

 The study involved the determination of some physiochemical and bacteriological properties in sachet-water samples taken within selected geopolitical wards in Jere and Maiduguri Metropolis. The purpose was to ascertain the quality of sachet water sold for consumption within the area. Ten samples were drawn, five from each study area. The samples were analysed for temperature, colour, turbidity, pH, conductivity, iron, total alkalinity and total dissolved solid. Bacteriological analysis was also carried out using multiple tube (most probable number) technique for enumeration of both total coli form count and differential Escherichia coli count. Other physical examination like volume, National Agency for Food and Drugs Administration and Control (NAFDAC) registration number, batch number, production date and expiry date were also examined. The results obtained were compared with World Health Organization (WHO), NAFDAC and Nigeria Standard of Drinking Water Quality (NSDWQ). Variations were observed among the entire samples in comparison with the standard. Some of the parameters conform to the standard like the Tempreture, pH, colour, odour, iron content and NAFDAC registration number while others like TDS, total alkalinity and volumetric quantity fell below the standard. The bacteriological analysis also showed that 80% of the samples studied revealed the presence of coliforms. Hence, there is need for regulatory agencies like NAFDAC and Standard Organisation of Nigeria (SON) to intensify effort in the routine monitoring of quality of sachet water marketed for consumption.DOI: http://dx.doi.org/10.3126/ije.v4i1.12177 International Journal of Environment Volume-4, Issue-1, Dec-Feb 2014/15, page: 48-57

Drinking water is a basic human need and must meet health requirements. Drinking water depots are a means of filling drinking water which is in the process of processing raw water using treatment and sterilization system. Drinking water depots as providers of drinking water must also meet the requirements of sanitation hygiene and personal hygiene management must also be maintained so that the water produced meets health requirements. The purpose of this study was to determine the effect of sanitation hygiene and personal hygiene management of refill drinking water depots on the quality of drinking water in terms of the Most Probable Number Coliform in Kediri. The research design used was analytic observational with cross sectional approach. The population of all refill drinking water depots in Kediri is 57, with the sampling technique that is Simple Random Sampling, where a portion of refill drinking water depots in Kediri are 50. Data is collected by check list, questionnaire and laboratory examination. The results showed that most of the hygiene sanitation of the drinking water depot had fulfilled the requirements of 77%, the drinking water personal hygiene depot was good as much as 85% and those who met the drinking water requirements were 70%. The results of the hygiene feasibility analysis showed the value of Sig 0.000<0.05 (R=0.935) means that there was an effect of hygiene sanitation quality with water quality in terms of the Most Probable Number Coliform. While the personal hygiene value of Sig 0.001 <0.05 (R = 0.528) indicates that there is a personal hygiene influence with water quality in terms of the Most Probable Number Coliform. The results of Logistic Regression test showed that there were effects of sanitation hygiene and personal hygiene management of refill drinking water depots with water quality in terms of the Most Probable Number Coliform with a significance value = 0.000 <a 0.05. This shows that the hygiene and the better personal hygiene at refill drinking water depots is increasingly fulfilling water quality requirements in terms of the Most Probable Number Coliform

Microorganisms like bacteria are frequently used as indicators of water quality in freshwater ecosystems. Thus, this study was conducted to evaluate the total coliforms (TC) and total aerobic heterotrophic bacteria (TAHB) present in the upstream (Kantagnos), midstream (lgang), and downstream (Kan-ipa) of Pagbanganan River. The most probable number (MPN/100 mL) of TC was determined through multiple tube fermentation test while counts of TAHB present in both water and sediments were enumerated by serial dilution and plating methods. MPN of TC revealed that the river water should not be used as a source of public water supply and as a venue for contact recreational activities like bathing and swimming. Furthermore, TAHB in the sediments of the river did not differ significantly across sites although their values showed a decreasing trend. Conversely, TAHB in the water column of the river significantly increased from upstream to downstream. These results are most probably influenced by the quarrying activities present in the area. In the upstream where there is no quarrying activity, TAHB was higher in sediment than in the water, while in the downstream where quarrying activities are present, it is otherwise. Because of these significant differences, it is believed that the ratios of TAHB present in the water column and sediments are potential indicators of sediment disturbance in the aquatic environment. The results of this study imply that proper management of Pagbanganan River by all sectors of the community is needed to keep it sustainable for safe use.

Abstract This study analyses the quality of sachet water consumed by university students in Metropolitan Kumasi, Ghana. Thirty sachet water samples from ten different brands were tested for their physical and bacteriological quality using meters and titrimetric method and most probable number method, respectively. Overall, one half of the sachet water samples were highly contaminated with total and faecal coliform. While the mean total coliform/100 mL concentration of ANG, NOV, IM, PD and DKN were 9.15 × 105, 2.35 × 106, 9.15 × 105, 4.15 × 105 and 9.15 × 105 respectively, we recorded faecal coliform counts of 2.3 × 105, 4.15 × 105, 2.3 × 105, 2.3 × 105 and 2.3 × 105, respectively for ANG, NOV, IM, PD and DKN. Moreover, samples from DKN brand showed Escherichia coli count of 4.0 × 104. The conductivity ranged from 2.24 μS/cm to 43.60 μS/cm while the mean total alkalinity of all samples ranged from 33.33 mg/L to 120 mg/L. The coliform contamination levels of the water samples violated the guidelines and standards of WHO for drinking water quality. Ghanaian regulatory agencies should intensify the monitoring and surveillance activities to ensure compliance with strict hygienic measures by sachet water producers.

The quality of drinking water supply must be guaranteed. The WHO (World Health Organization) determines water quality by means of E. Coli bacteria. Based on the Minister of Health Regulation No. 492 / MENKES / PER / IV / 2010 The maximum permissible content of E. Coli in drinking water is 0 per 100 ml. The presence of E. coli in water is an indicator of human and animal fecal pollution that can cause diarrhea and even death. Selection of Refillable Drinking Water (AMIU) as an alternative to fulfill drinking water needs is a risk that can endanger health if the quality of AMIU is added if consumers do not pay attention to safety and hygiene. This study aims to see the content of E. coli in Refill Drinking Water (AMIU) in Samatiga District, West Aceh Regency. This research is experimental with cross sectional design using quantitative laboratory examination with the Most Probable Number (MPN) method. The population in this study were all refill drinking water depots that did not have a drinking certificate in Samatiga District, West Aceh Regency. The research sample used a total sampling method of 7 refill drinking water depots. The results of the analysis showed that from all samples as many as 6 samples (85.71%) tested positive for Escherichia coli bacteria and 1 sample (14.29%) tested negative for Escherichia coli bacteria. Based on the calculation of the number of colonies with the MPN / 100 ml table then comparing with the requirements of the Regulation of the Minister of Health of the Republic of Indonesia Number 492 / Menkes / Per / IV / 2010 concerning drinking water quality requirements that the 6 samples tested positive were not suitable for consumption.

This paper deals with the suitability of Surface and Ground water quality of Western Yamuna Canal in Haryana, India for irrigation and other use. The major water use of this canal is for irrigation purpose (94%), domestic water use (4%) and industrial and other uses (2%).The rapid increase inurbanization and industrialization is leading towards deterioration of water quality. In this study, analysis is performed to identify the groundwater and surface water quality in the vicinity of Radaur-Ladwa stretch. Direct disposal of domestic and industrial wasteobstructs the flow of Western Yamuna Canal thus water is stagnant at most places and self-purification mechanism of water is occurring no more. This study reveals that the surface water of the Western Yamuna Canal comes under E class of water, which is unfit for domestic use, propagation of wildlife and fisheries. However it is found suitable for irrigational and industrial cooling purpose only. Most Probable Number (MPN) values are high in the ground water, which indicates microbial contamination of water and require immediate action for up-grading existing treatment facilities.The result indicates alarming signs and suggests immediate response for policy along with adaptation and mitigation to bring at full stop to contaminating activities. If water contamination is continued likewisea time will come soon that the water qualityof Radaur-Ladwa stretch (Western Yamuna Canal) will be unfit for irrigational purpose too.
