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 ...

Global Water Research Council selects best bioanalysis tools for endocrine disrupting chemicals
The aim of this fact sheet is to review the methodology used to establish guideline values for inorganic and organic chemicals which may be found in drinking water. Such guidance is needed to assist the management of good water quality when the potential for adverse health effects, based on the intrinsic toxicity of the chemical, requires some quantitative description of limits which should be ...

A critical evaluation of two point-of-use water treatment technologies: can they provide water that meets WHO drinking water guidelines?
Point-of-use (POU) technologies have been proposed as solutions for meeting the Millennium Development Goal (MDG) for safe water. They reduce the risk of contamination between the water source and the home, by providing treatment at the household level. This study examined two POU technologies commonly used around the world: BioSand and ceramic filters. While the health benefits in terms of ...

Household rainwater harvesting system – pilot scale gravity driven membrane-based filtration system
This paper presents the results of a pilot scale study consisting of pre-treatment with a granular activated carbon (GAC) filter followed by membrane filtration. Detailed characterisation of rainwater tanks has highlighted that turbidity, dissolved organic carbon (DOC) and heavy metals, in particular lead, were not compliant with the 2004 Australian Drinking Water Guidelines (ADWG). Further, ...

Design and management of rainwater harvesting systems to control water quality for potable purposes in Cu Khe, Vietnam
There are debates about whether rainwater is suitable as drinking water. A serious shortcoming of the debate is that there are differences in the design and management of rainwater harvesting (RWH) systems. This study is based on the performance of two RWH systems that are used for drinking purposes at a kindergarten and a primary school in Cu Khe, Vietnam. Each system comprised a painted ...

Gravity driven membrane filtration system to improve the water quality in rainwater tanks
The characterisation of rainwater in metropolitan Sydney and in rural New South Wales was undertaken. The results showed that factors such as the lack of vehicular traffic, air pollution and urban contamination meant that rural rainwater water quality was better. The rain water collected in both metropolitan and rural areas generally complied with the 2004 Australian Drinking Water Guidelines ...

Activity concentration and dose estimation of 226Ra, 232Th, 40K and 137Cs in drinking water of selected areas of Punjab, Pakistan
Radioactivity of naturally occurring (226Ra, 232Th and 40K) and anthropogenic (137Cs) radioactive nuclides was measured in 29 potable ground and surface water samples of Punjab, Pakistan. The results showed average activity concentrations for 226Ra, 232Th, 40K and 137Cs as 1.09, 0.55, 16.17 and 0.40 Bql−1, respectively. 137Cs was detected in only a few samples. The obtained results showed ...

Evaluation of nitrate and perchlorate reduction using sulfur-based autotrophic and mixotrophic denitrifying processes
The biological reduction of nitrate and perchlorate was comparatively evaluated in autotrophic and mixotrophic bioreactors using elemental sulfur and/or methanol as the energy source. The mixotrophic reactor was supplemented with methanol at CH3OH/NO3−-N ratio of 1 or 1.4. The mixotrophic reactor completely reduced perchlorate in the feed up to 1,000 μg l−1. The autotrophic reactor also ...

Internal Guidelines and TSCA: The Implications of EPA`s Case Against DuPont
The United States Environmental Protection Agency (EPA) has urged industry for years to view federal environmental standards as floors, not ceilings. Companies have been urged at every opportunity to do better than what the law requires, and to improve upon federally enforced environmental standards whenever possible. Many in industry have heeded the call and have proactively established ...

Drinking Surface Water Pilot - Case Study
Bowen Island Municipality’s Cove Bay Water System (CBWS) treats surface water from Grafton Lake to drinking water. Historically, the lake water was treated with hypochlorite addition however this treatment is insufficient to meet the Canadian Drinking Water Quality Guidelines (CDWQG) for several parameters including protozoa, turbidity, manganese and colour. ...

An international review of the challenges associated with securing buy-in for water safety plans within providers of drinking water supplies
Since publication of the 3rd Edition of the World Health Organisation (WHO) Drinking Water Quality guidelines, global adoption of water safety plans (WSPs) has been gathering momentum. Most guidance lists managerial commitment and ‘buy-in’ as critical to the success of WSP implementation; yet the detail on how to generate it is lacking. This commentary discusses aspects of managerial commitment ...

World Health Organization`s (WHO) Guidelines for drinking-water quality (GDWQ)
The World Health Organization's (WHO) Guidelines for drinking-water quality (GDWQ) were developed with the primary goal of enforcing protection on human health concerning the quality of drinking water. Consequently, it ensures public health is considered during the formulation and implementation of regional and national drinking-water actions and policies. Other objectives include: Providing a ...

Organic matter removal and disinfection byproduct management in South East Queensland's drinking water
Over the past several decades, much research has been carried out to understand and control the formation of disinfection byproducts (DBPs) of potential human health concern in drinking water. The majority of these studies have taken place in continental climates of North America and Europe, with less work investigating waters in tropical and subtropical climates. This study evaluated the ...

Spatial distribution and sources of dissolved trace metals in surface water of the Wei River, China
For this study, 34 water samples were collected along the Wei River and its tributaries. Multivariate statistical analyses were employed to interpret the environmental data and to identify the natural and anthropogenic trace metal inputs to the surface waters of the river. Our results revealed that Zn, Se, B, Ba, Fe, Mn, Mo, Ni and V were all detected in the Wei River. Compared to drinking ...

Perceived agricultural runoff impact on drinking water
Agricultural runoff into surface water is a problem in Australia, as it is in arguably all agriculturally active countries. While farm practices and resource management measures are employed to reduce downstream effects, they are often either technically insufficient or practically unsustainable. Therefore, consumers may still be exposed to agrichemicals whenever they turn on the tap. For rural ...
