For greywater, river water and secondary treated sewage, total coliform and E. coli removal efficiencies were not significantly different for the tested samples and varied in the range of 2.22–2.53 log10 units at a current density of 1 mA/cm2 and electrolysis time of 30 min. ...
The ten mandatory parameters are core parameters which all water service providers nationwide are obligated to test. These include thermotolerant coliforms or Escherichia coli, arsenic, cadmium, lead, nitrate, color, turbidity, pH, total dissolved solids, and disinfectant residual. ...
This was done by checking pH, running quantitative analyses of heavy metals and testing for total coliforms. The effect of ultraviolet (UV) rays on samples positive for coliforms was evaluated. ...
This diagnosis would not have been possible using conventional testing methods. A non-phosphonate antiscalant was recommended, which when implemented resolved the problem. ...

Source waters (n = 74) including bottled water, well water and surface water were assessed for enumerating total coliforms and faecal coliforms using the membrane filtration method. The results showed that 18.5 and 14.8% of bottled water samples were contaminated with total coliforms and faecal coliforms, ...

The presence/absence hydrogen sulphide test (P/A H2S) is widely used as a low-cost alternative faecal indicator test in remote and resource-poor settings. ...
The value of reporting total coliform results in drinking water is a topic of debate. Total coliform and Escherichia coli results from small drinking water systems tested over a 3-year period in British Columbia were analyzed using life table analysis. ...
Sanitary surveys and bacteriological testing for total coliforms and Escherichia coli (EC) using Colilert® were conducted at nearly 80 water sources serving eight villages. ...
In total, 108 samples were collected: 15 from the Gola river, 51 from water taps, 24 from water treatment plants and 18 from tube wells. Samples were tested for coliforms by the most probable number technique. Identification of species was done by standard procedures. ...
