Phosphorus and bacterial growth in drinking water.
The availability of organic carbon is considered the key factor to regulate microbial regrowth in drinking water network. However, boreal regions (northern Europe, Russia, and North America) contain a large amount of organic carbon in forests and peatlands. Therefore, natural waters (lakes, rivers, and groundwater) in the northern hemisphere generally have a high content of organic carbon. We f...
متن کاملBacterial Quality of Drinking Water in Bushehr Intercity Buses in 2010
Background and Objective: Road transportation and specifically bus travel accounts for the bulk of travel. Contaminated drinking water consumption is one of the issues that threaten health, and always there is pollution possibility in drinking water in buses. This study evaluated the microbial quality of consumed drinking water in buses and also compared it with available standards. Materials a...
متن کاملBacterial Community Analysis of Drinking Water Biofilms in Southern Sweden
Next-generation sequencing of the V1-V2 and V3 variable regions of the 16S rRNA gene generated a total of 674,116 reads that described six distinct bacterial biofilm communities from both water meters and pipes. A high degree of reproducibility was demonstrated for the experimental and analytical work-flow by analyzing the communities present in parallel water meters, the rare occurrence of bio...
متن کاملFactors affecting bacterial growth in drinking water distribution system.
OBJECTIVE To define the influence of some parameters, including assimilable organic carbon (AOC), chloramine residual, etc. on the bacterial growth in drinking water distribution systems. METHODS Three typical water treatment plants in a northern city (City T) of China and their corresponding distribution systems were investigated. Some parameters of the water samples, such as heterotrophic p...
متن کاملUptake of nutrients and organic C in streams in New York City drinking-water-supply watersheds
Uptake of nutrients and organic C was measured once annually between 2000 and 2002 in each of 10 streams within the water-supply source areas for New York City. Nutrients (PO4 3– and NH4 þ) and organic C (glucose and arabinose) were injected into the streams for 1 to 2 h, and uptake lengths were estimated from the longitudinal declines in downstream concentration relative to that of a conservat...
