Water needed for daily use is viable water that is clean and healthy. Due to limited access to clean water, people buy bottled water and refillable drinking water. It is necessary to do clinical research at the laboratory to determine whether the water condition is feasible or not for consumption. The purpose of this study was to determine whether or not there is E.coli bacteria in the refillable drinking water and bottled water. This study uses an experimental method. Samples were taken from 15 refillable drinking water depots in Kecamatan Rawalumbu Bekasi and 15 bottled water samples. The bacterias identification was made by planting the samples in Blood Agar media and EMB. The results showed four positive samples of E. coli bacteria (26.7%) in the refillable drinking water depot at Kecamatan Rawalumbu Bekasi and one positive sample of E. coli bacteria (6.7%) in bottled water. It was also found that other types of bacteria such as Coliform (6.7%), Pseudomonas sp. (40%), Klebsiella sp. (13.3%), Staphylococcus sp. (6.7%), and Streptobacillus Gram + (13.4%). Key words: Refillable Drinking Water, Bottled Water, Escherichia coli.

Abstract: Water is a vital requirement for all living creatures. Standards for monitoring drinking water and clean water for other uses are rare. Besides that, water sources such as wells are contaminated by many pollutants. According to the laboratory results conducted by the Tuminting Public Health Centre, wells used in the Tuminting District, Manado, have experienced E. coli contamination. The aim of this research was to identify factors associated with E. coli in the water of wells in the Tuminting District. The method used in this research was descriptive analysis. Through interviews and checklists of wells’ owners, primary data were collected and then laboratory examinations of well-water samples were carried out. Secondary data were collected from the Health Department of Manado, and the Health Centre and the District Office of Tuminting. We used 30 water samples by simple random sampling of 67 wells. Data were analyzed through univariate and bivariate correlation tests. The results showed that E. coli in well water used by the public in the Tuminting District exceeded the standard of clean water according to the Regulations of the Ministry of Health Republic of Indonesia No.416/MENKES/PER/IX/1990 and of drinking water according to the Decree of Health Ministry No. 907/MENKES/SK/VII/2002. Moreover, there was a significant relationship between the distance of wells to septic tanks and the E. coli contents in well water. We suggest that the government improve the construction of wells and septic tanks, provide qualified water supply, and introduce the usage of chlorine to achieve clean water and a better all round health status for the Tuminting public. Keywords : water, wells, E coli, septic tank     Abstrak: Air merupakan kebutuhan vital bagi semua mahluk hidup. Standar monitoring air minum maupun untuk penggunaan lainnya masih jarang. Selain itu, sumber air seperti sumur telah dicemari oleh berbagai polutan. Hasil pemeriksaan laboratorium yang dilaksanakan oleh Puskesmas Tuminting  menunjukkan bahwa sumur gali di kelurahan Tuminting  telah tercemar Esherichia coli. Tujuan penelitian untuk mendapatkan faktor-faktor yang berperan terhadap pencemaran E. coli dalam air sumur kelurahan Tuminting.  Metode penelitian yang digunakan yaitu deskriptif analitik. Data primer dikumpulkan melalui wawancara dengan pemilik sumur gali dengan menggunakan check list, dilanjutkan dengan pemeriksaan laboratorium terhadap sampel air sumur gali. Data sekunder diambil dari Dinas Kesehatan Kota Manado serta Puskesmas Tuminting dan Kantor Kelurahan Tuminting. Sampel ditentukan dengan metode simple random dan diperoleh 30 sampel air dari 67 sumur gali. Data dianalisis secara univariat dan bivariat dengan menggunakan uji korelasi. Hasil penelitian menunjukkan bahwa kandungan E. coli dalam air sumur gali yang digunakan oleh masyarakat di Kelurahan Tuminting melebihi standar baku mutu air bersih sesuai dengan Peraturan Menteri Kesehatan RI Nomor 416/MENKES/PER/IX/1990 maupun dari air minum sesuai dengan Keputusan Menteri Kesehatan RI Nomor 907/MENKES/SK/VII/2002. Selain itu terdapat hubungan yang bermakna antara jarak sumur gali ke septic tank dan kandungan E. Coli dalam air sumur gali. Disarankan kepada pihak pemerintah daerah untuk melakukan perbaikan konstruksi sumur gali maupun septic tank, menyediakan air bersih yang memenuhi syarat kesehatan, dan sosialisasi kepada masyarakat tentang penggunaan air bersih dan kaporisasi.

Monitoring of bacteria concentrations is of great importance in drinking water management. Continuous real-time monitoring enables better microbiological control of the water and helps prevent contaminated water from reaching the households. We have developed a microfluidic sensor with the potential to accurately assess bacteria levels in drinking water in real-time. Multi frequency electrical impedance spectroscopy is used to monitor a liquid sample, while it is continuously passed through the sensor. We investigate three aspects of this sensor: First we show that the sensor is able to differentiate Escherichia coli (Gram-negative) bacteria from solid particles (polystyrene beads) based on an electrical response in the high frequency phase and individually enumerate the two samples. Next, we demonstrate the sensor’s ability to measure the bacteria concentration by comparing the results to those obtained by the traditional CFU counting method. Last, we show the sensor’s potential to distinguish between different bacteria types by detecting different signatures for S. aureus and E. coli mixed in the same sample. Our investigations show that the sensor has the potential to be extremely effective at detecting sudden bacterial contaminations found in drinking water, and eventually also identify them.

Water Microbiology

Escherichia coli has had a central place in water microbiology for decades as an indicator of faecal pollution. It is only relatively recently that the role of E. coli as pathogen, rather than indicator, in drinking water has begun to be stressed. Interest in the role of E. coli as a cause of diarrhoeal disease has increased because of the emergence of E. coli O157:H7 and other enterohaemorrhagic E. coli, due to the severity of the related disease. There are enterotoxigenic, enteropathogenic, enterohaemorrhagic, enteroinvasive, enteroaggregative and diffusely adherent strains of E. coli. Each type of E. coli causes diarrhoeal disease through different mechanisms and each causes a different clinical presentation. Several of the types cause diarrhoea by the elaboration of one or more toxins, others by some other form of direct damage to epithelial cells. This paper discusses each of these types in turn and also describes their epidemiology, with particular reference to whether they are waterborne or not.

Of Greece

The aim of this study was to gather information on the spread of antibiotic resistance in Escherichia coli isolates from wells, boreholes and untreated drinking water in islands of Greece. We analyzed for antibiotic resistance 235 E. coli strains isolated from untreated drinking water of small rural communities, and ground water from 4 islands. Resistance was tested against Norfloxacin, Ciprofloxacin, Levofloxacin, Amoxicillin and Cefaclor. More than half (54.9%) were resistant to at least one of the antibiotics tested. Of these 26.3% showed multiple resistance (to two or more antibiotics). Strains from drinking water sources were overall more sensitive. Frequent resistance was observed for Amoxicillin (38.3%) and Levofloxacin (28.5%), low for Norfloxacin (5.5%).
