Water is used for various human activities such as drinking, bathing, washing and recreation. The physicochemical as well as microbiological qualities of water samples collected over a period of ten months from five swimming pools in five randomly-selected hotels in Osogbo metropolis, Southwestern Nigeria were assessed. The collection of the fifty water samples spanned the dry and rainy seasons...

Previous studies have shown that mismanaged swimming pools could transmit water-borne diseases. The objective of the present study was the quality assessment of chemical, biological and physical characteristics of swimming pools in Shahrekord city, southwest of Iran. The two main indoor swimming pools of Shahrekord city were considered during the summer and winter of 2013. The number of 459 sam...

BACKGROUND Dental unit waterlines (DUWLs) are ideal environment for development of microbial biofilms. Microbial contamination of water in DUWLs is thought to be the result of biofilm formation as it could serves as a haven for pathogens. The aim of this study was to assess microbial quality of water in dental unit waterlines of dental units located at the dental school of Isfahan University of...

Heterotrophic plate count (HPC) constitutes a common indicator for monitoring of microbiological water quality in distribution systems (DS). This paper aims to identify factors explaining the spatiotemporal distribution of heterotrophic bacteria and model their occurrence in the distribution system. The case under study is the DS of Quebec City, Canada. The study is based on a robust database r...

The occurrences of trihalomethanes (THMs), haloacetic acids (HAAs) and heterotrophic bacteria were monitored in five small water systems over a nine-month period to investigate the association between HAA degradation and heterotrophic bacteria populations. The sampling sites were chosen to cover the entire distribution network for each system. An inverse association between heterotrophic bacter...

Abstract This study determined the water quality of three major domestic sources Bontoc, Mountain Province, and recommended interventions to maintain parameters within values set by Philippine National Standards for Drinking Water (PNSDW). Results revealed that all average physico-chemical measured during wet dry seasons samples from different sampling points are allowable range except turbidit...

The plate loop count as described in Standard Methods for the Examination of Dairy Products, 13th Edition, was investigated as a simplified technique for determining total viable counts in single strength orange juice. This pro cedure requires the use of standardized loops (0.01 and 0.001) for making serial dilutions in stead of pipets and dilution bottles. Data have been presented to show ther...

Due to the fact the incubation conditions may influence the microbiological evaluation of water for dialysis, the objective of the present study was the comparison of the efficiency of R2A and PCA media in the enumeration of heterotrophic bacteria in 193 samples of water collected in dialysis clinics from 12 cities in São Paulo, between October and December 2007. Results showed counts significa...
