Perspectives on drinking water monitoring for small scale water systems
Drinking water (DW) is increasingly subject to environmental and human threats that alter the quality of the resource and potentially of the distributed water. These threats can be both biological and chemical in nature, and are often cumulated. The increase of technical frame of water quality monitoring following the evolution of water quality standards guarantee the regulation compliance in ...

THM monitoring in a drinking water plant in the east of Spain - Case Study
APPLICATION Online THM monitoring at a drinking water plant. CUSTOMER Water Utility PROBLEM The local health authority had warned that the THM level in the water supplied to households in the region was above or near the limit imposed by the law. For this reason, the local WTP was asked to install an on-line THM monitoring system and implement improved control of the ...

Turbidity tubes for drinking water quality assessments
Turbidity tubes have been considered to be the field method of choice for drinking water quality monitoring in resource-limited contexts because of their relative simplicity and low cost in comparison with conventional (nephelometric) turbidimeters. These tubes utilise the principle of visual extinction of a submerged target for turbidity determination and were therefore thought to be subject to ...

Drinking water quality monitoring using trend analysis
One of the common quality parameters for drinking water is residual aluminium. High doses of residual aluminium in drinking water or water used in the food industry have been proved to be at least a minor health risk or even to increase the risk of more serious health effects, and cause economic losses to the water treatment plant. In this study, the trend index is developed from scaled ...

Supply system factors associated with microbiological drinking water safety in regional New South Wales, Australia, 2001–2007
Aim: To determine factors associated with microbiological safety of public drinking water systems in regional New South Wales (NSW), Australia. Method: We analysed 107,000 end-user drinking water samples for an association between detection of Escherichia coli and drinking water system features, sample year and season using NSW Health Drinking Water Monitoring Program data, 2001–2007. We used ...

Relating water quality monitoring to disinfection by-product formation in four pilot treatment streams
With increasing focus on the health implications from disinfection by-products (DBP) in drinking waters, appropriate monitoring parameters are required that can give rapid information on the potential of a treated water to form DBPs. Given that the most effective strategy for the reduction of concentrations of DBPs is the removal of their precursor, natural organic matter, parameters that ...

Monitoring of three drinking water treatment plants using flow cytometry
A 4-month sampling campaign has been conducted for the monitoring of three drinking water treatment plants using flow cytometry and culture-based methods to provide information related to changes in bacterial concentration according to treatments. Flow cytometry is a fast and user-friendly technique enabling bacteria quantification and viability assessment in less than 1 hour. Specific profiles ...

Safety in Drinking Water? Monitoring for Radioactive ContaminantsOnly Required Every Three, Six, or Nine Years per Federal Law
Current federal law requires testing of drinking water for radionuclides, “hazardous radioactive materials” every three, six, or nine years. The states have the option to increase testing frequency. [Federal Register Year 2000; page 76746. http://www.gpoaccess.gov/fr/retrieve.html] An incident of terrorism, accident, or improper disposal of radioactive materials will surely ...

EPA 2009 Protective Action Guideline Levels
WE HAVE BEEN WAITING SINCE 1992 THE Old Document: In 1992 the EPA published its Manual of Protective Action Guides and Protective Actions for Nuclear Incidents. This is an excellent manual. But One Major Fault: All radiation levels are given in REM per year. There is no guidance for the layman in terms airborne or waterborne concentrations in terms of micro Cuires or Becquerel /Liter for ...

Organisational arrangements and drinking water quality
This paper discusses the findings of a research project which explored the impact of varying organisational arrangements on drinking water quality in England and Wales, and the Republic of Ireland. It is established that drinking water quality has been of a consistently higher standard in England and Wales in comparison with the Republic of Ireland. It is also demonstrated that the associated ...

Success or failure: demonstrating the effectiveness of a Water Safety Plan
The Water Safety Plan (WSP) concept has become a globally recognised and accepted approach to drinking water supply management and operation. Many countries around the world are adopting this proactive, risk-based model for ensuring consistent confidence in drinking water safety, accessibility and affordability. While it is widely accepted that the WSP concept is an appropriate tool for ensuring ...

Organic sum parameters for river monitoring
The purpose of river monitoring is to have an early warning system for chemical accidents with the consequence of water pollution through hazardous chemical substances. The real objective goes even further because the early warning system is intended for protecting the sensible drinking water resources. River monitoring stations have been established along rivers around the world. Today there is ...

Methods for microbiological quality assessment in drinking water: a comparative study
The present study aimed to compare several methods for quantifying and discriminating between the different physiological states of a bacterial population present in drinking water. Flow cytometry (FCM), solid-phase cytometry (SPC), epifluorescence microscopy (MSP) and culture method performances were assessed by comparing the results obtained for different water samples. These samples, ...

Early warning system to forecast maximum temperature in drinking water distribution systems
Climate change poses new challenges in preventing the exceedance of the maximum allowed temperature in the drinking water distribution system (DWDS). The objective of this article is to evaluate the feasibility of forecasting the maximum temperature in the DWDS. Two options were analysed: (1) using the records of the last day as forecast for the coming 2 days and (2) using 2-day weather ...

Australian Drinking Water Guidelines
The Australian Drinking Water Guidelines (ADWG) were developed to provide regulations that ensure drinking water safety. Drinking water under the guidelines is described as water used for human consumption, and it is obtained through a tap or food made using water. It also ensures that water quality meets the intended purpose of use. The National Health and Medical Research Council (NHMRC) works ...
