The aim of this experiment was to study the effect of the application of pig slurry on potential pathogen (total and faecal coliform bacteria) presence in a Typic Xerofluvent soil. The experiment was conducted in field conditions, in the Segura River valley in the South East of Spain. Four treatments, in a fully-randomised design with three replicates per treatment, were established in experime...

Street-vended foods and beverages, an integral part of urban economies in the developing world, have been implicated in cholera transmission in Latin America. To improve the microbiologic quality of market-vended beverages in Guatemala, we tested a simple system consisting of dilute bleach (4.95% free available chlorine) for water purification, narrow-mouth plastic vessels with spigots for disi...

This study focused upon the determination of physicochemical and microbial properties, including metals, selected anions and coliform bacteria in drinking water samples from hand-dug wells in the Kumasi metropolis of the Republic of Ghana. The purpose was to assess the quality of water from these sources. Ten different water samples were taken from different parts of Kumasi, the capital of the ...

OBJECTIVE To determine the frequency of microbiological contamination of water in different water filtration plants in Islamabad. STUDY DESIGN Descriptive cross-sectional study. PLACE AND DURATION OF STUDY Water Filtration Plants (WFP) in different sectors of Islamabad, from April to September 2012. METHODOLOGY Water samples were collected in sterilized bottles according to the standard w...

In the bacteriological testing of rural raw water supplies the laboratory is having to face, constantly, the problem of evaluating the sanitary significance of the atypical coliform bacteria so often recovered from positive tests. For several years the author and associates have carried on studies of these bacteria as a corollary to the water-testing service that is maintained for the rural pub...

Fecal coliform bacteria are the most common pollutant in rivers and streams. In Louisiana, it has been reported that 37% of surveyed river miles, 31% of lakes, and 23% of estuarine water had some level of contamination. The objective of this research was to assess the effect of surface runoff amounts and rainfall amount parameters on fecal coliform bacterial densities in Bayou Dorcheat in Louis...

The location of a well related to surface drainage ways is important in determining the potential for groundwater contamination from surface water flow. Locating a well in a safe place needs careful consideration and planning.To determine the effects of well depth on water quality, the wells up to 4 m. depth and 100 m. far from river were selected in Isfahan. Geologically, the earth in this zon...

OBJECTIVE To analyze backcountry-area water quality in US Department of Agriculture Forest Service-designated wilderness areas for the presence of coliform and potentially pathogenic bacteria. METHODS Thirty-one backcountry lakes and streams were selected that would stratify the risk based on use by backpackers, pack animals, commercial grazing animals, or natural unaffected wilderness areas....

Malacca River water quality is affected due to rapid urbanization development. The present study applied LULC changes towards water quality detection in Malacca River. The method uses LULC, PCA, CCA, HCA, NHCA, and ANOVA. PCA confirmed DS, EC, salinity, turbidity, TSS, DO, BOD, COD, As, Hg, Zn, Fe, E. coli, and total coliform. CCA confirmed 14 variables into two variates; first variate involves...

Despite significant progress in the control of contagious pathogens, environmental mastitis continues to be a major cause of financial loss to the UK dairy industry. This paper presents some findings from a field study designed to investigate the incidence and significance of coliform infections acquired during the non-lactating period. The bacteriological status of two quarters from each of 62...
