The MI agar, Colilert®, Chromocult coliform® agar, and DC with BCIG agar chromogenic culture-based methods used to assess microbiological quality of drinking water were compared in terms of their ubiquity, sensitivity, ease of use, growth of atypical colonies and affordability. For ubiquity, 129 total coliform (representing 76 species) and 19 Escherichia coli strains were tested. Then, 635 1-L well water samples were divided into 100 mL subsamples for testing by all four methods. Test results showed that 70.5, 52.7, 36.4, and 23.3% of the non-E. coli total coliform strains and 94.7, 94.7, 89.5, and 89.5% of the 19 E. coli strains yielded a positive signal with the four methods, respectively. They also yielded a total coliform positive signal for 66.5, 51.7, 64.9, and 55.0% and an E. coli positive signal for 16.1, 14.8, 17.3, and 13.4% of the 635 well water samples tested, respectively. Results showed that Colilert® is the most expensive method tested in terms of reactants, yet it is the easiest to use. Large numbers of atypical colonies were also often observed on Chromocult coliform® and DC with BCIG, thereby challenging the target microorganism count. Thus, the MI agar method seems to be the best option for the assessment of drinking water quality.

Water safety plans (WSPs) is a comprehensive health-based risk assessment and risk management approach to optimizing drinking-water safely from catchments to consumer. The focus of this research is the development and implementation of water safety plans (WSPs) to be used by the water supplier. The study was conducted at 13 districts and 18 upazills (rural and urban) among the whole Bangladesh. The data were collected during March to May, 2008 to conduct the study. In the study, primary data were collected directly from the respondents while secondary data were collected from different records available at different office, internet and journals. It was found that deep tube well and shallow tube well water was used for drinking purposes by 31.43% and 24.29% respondents respectively where as minority of the respondents used other sources. Perception about the safe drinking water for the respondents was found mostly 63% among all the respondents followed by moderately safe 21%.

Abstract Safe drinking water is directly linked to good human health. An excessive amount of manganese (Mn) in drinking water supplies causes people show symptoms of neurotoxicity. In this study, the level of Mn in potable water sourced from tube wells located in 9 (nine) districts of Bangladesh was monitored. In total 170 (one hundred and seventy) water samples were collected and Mn was quantified by atomic absorption spectroscopy (AAS). The levels of Mn found in the tube well water samples of Sirajganj, Meherpur, Chuadanga, Jhenaidah, Magura, Faridpur, Jashore, Satkhira, and Khulna were 0.37–1.86, 0.10–4.11, 0.30–0.76, 0.26–0.94, 0.01–0.18, 0.21–1.78, 0.08–1.23, 0.05–0.27 and 0.01–2.11 mg/L, respectively. Results revealed that Mn level was beyond the highest contaminated levels of 0.1 mg/L and 0.4 mg/L, which are recommended by Bangladesh Drinking Standard (BDS) and World Health Organization (WHO), respectively. The maximum Mn contaminated level reached up to 4.11 mg/L (mean: 0.53 mg/L). The Mn level in tube well water exceeded 51.1% and 75.9% set by the recommended value of WHO and BDS, respectively. Furthermore, the calculated hazard quotient (HQ) value for Mn was observed to be greater than unity, indicating both children and adults risked potential non-carcinogenic health issues. The water supply authorities should take steps to provide Mn-free drinking water for communities.

ABSTRACT Five tube-wells in Matlab, Bangladesh, were selected for analysis of selected biophysicochemical parameters. The results showed that all tube-well water samples contained zooplankton and bacteria. Results for some of the parameters were outside the accepted limits recommended by the World Health Organization for drinking water. It is concluded that water from tube-wells should be treated if used as drinking water.

MI agar and Colilert®, as well as mFC agar combined with an Escherichia coli-specific molecular assay (mFC + E. coli rtPCR), were compared in terms of their sensitivity, ease of use, time to result and affordability. The three methods yielded a positive E. coli signal for 11.5, 10.8, and 11.5% of the 968 well water samples tested, respectively. One hundred and thirty-six (136) samples gave blue colonies on mFC agar and required confirmation. E. coli-specific rtPCR showed false-positive results in 23.5% (32/136) of cases. In terms of ease of use, Colilert was the simplest method to use while the MI method provided ease of use comparable to all membrane filtration methods. However, the mFC + E. coli rtPCR assay required highly trained employees for confirmation purposes. In terms of affordability, and considering contamination rate of well water samples tested, the Colilert method and the mFC + E. coli rtPCR assay were at least five times more costly than the MI agar method. Overall, compared with the other two methods tested, the MI agar method offers the most advantages to assess drinking water quality.

Drinking water quality is an actual and stringent problem and the presence of nitrate and nitrite ions above limits imposed by legislation may produce methemoglobinemia and different types of cancer. Because nitrate is odourless, colourless and tasteless is undetectable without tests and well water is recommended to be evaluated from this point of view, especially when in the proximity of the wells are activities which may contribute to water contamination. The present research was carried out with aim to achieve nitrate and nitrite levels from wells located in three areas from Muntenia region: Chiajna (Ilfov), Letca Noua (Giurgiu) and Manastirea (Calarasi). The obtained results evidenced that 10 from 14 analysed wells contain nitrate levels were over imposed limit, one of them located in Manastirea (Calarasi) being even 4 times higher. Regarding nitrite, water from one sampling point is over 0.5 mg/L, all the rest being lower and much lower than imposed limit.

The protective activity of lime juice against cholera was suggested in a recent case-control study from Guinea-Bissau, On the basis of these findings, we investigated the vibriocidal properties of juice from lime (Citrus aurantifolia) fruits added to well water, tap water, and food samples. Well-water samples showed initial pH values from 3.5 to 4,9 whereas water samples from municipal or private taps showed initial pH values between 7.5 and 8.3, A 5-log reduction in Vibrio cholerae O1 counts to <100 CFU/ml of well water was shown for two test strains after exposure to 0.5% lime juice (pH 3.3) for 12 min. In tap water, no significant reduction in CFU of V. cholerae was found after exposure to 0% (pH 8.3) and 0.5% (pH 5.6) lime juice whereas exposure to 1.0% lime juice (pH 4.4) for 120 min caused a 5-log reduction to <100 CFU/ml of tap water for the test strains. A 3-log reduction of V. cholerae was found in food samples containing 3.5% and 5.0% lime juice after 120 min exposure. Our results show that during epidemics of cholera in areas without safe sources of drinking water, juice from citrus fruits added to water and food in palatable concentrations may be appropriate measures in reducing the transmission of cholera. However, local characteristics of the water, in particular its alkalinity, should be considered before applying this measure.
