Abstract:

A drinking water supply system is an extraordinarily complex system—consisting of kilometers of pipes and various tanks, valves, pumps, and other equipment. This complexity makes it extremely vulnerable to physical, chemical, and/or biological hazards. Therefore, the vulnerability assessment of a drinking water supply system to identify the critical control points is absolutely necessary. This paper assesses the vulnerability of the drinking water supply systems. The assessment is elaborated in systems using water from surface water bodies and groundwater bodies. The critical control points ar

Due to the urgent need for water in all parts of industrial or developing societies, water supply, and transmission facilities are suitable targets for biological risks.

Abstract:

Poor surface water quality is still a significant problem in many parts of the world. It can often limit the use of this vital resource and in more extreme cases can harm human and other life. A basic need is to establish the nature, extent and magnitude of the problems. To gain a quantitative picture it is necessary to undertake detailed quality and status assessments. Such assessments establish the scope of environmental impacts and effects, and provide a quantitative baseline against which future quality can be compared and progress monitored.

Abstract Ammonium pollution of source water has become a challenge in rural water supply.

This study was conducted to investigate ammonium removal by biological up-flow roughing filter packed with ceramic media. Low flow rate did affect the ammonium removal and higher flow rate was suggested, while intense backwashing only showed a slight impact. At 4 m/h, an average reduction of about 51% was obtained, and NH4+-N effluent concentration could be below 0.5 mg/L

Abstract:

In developed countries water managers are constantly under pressure to provide the clean and safe water. Traditionally, and for at least the past 100 years, the management of biological water quality has relied on the use of microbial indicator organisms to assess the potential risk of water-borne disease. However, over the past few years, there have been a number of critical reviews of guidelines and standards for managing risk in water storage, treatment and supply. International, national and state agencies have initiated these reviews and have all generally agreed that technology for alter

AbstractTerrorist attacks on critical infrastructures can cause problems to a national stability and functioning. Food and water supply chains are some of the most important infrastructures, and it is the country’s (government’s) obligation to provide sufficient quantities of food and water to its population. Intentional food contamination can, among other motives, originate from an act of terrorism (with political or ideological motives) with the aim of causing fear (terror) among people. Food defence systems can help assess vulnerabilities, determine mitigation strategies for terrorist attac

Abstract:

The Southern African Millennium Ecosystem Assessment (SA f MA) evaluated the relationships between ecosystem services and human well-being at multiple scales, ranging from local through to sub-continental. Trends in ecosystem services (fresh water, food, fuel-wood, cultural and biodiversity) over the period 1990–2000 were mixed across scales. Freshwater resources appear strained across the continent with large numbers of people not securing adequate supplies, especially of good quality water. This translates to high infant mortality patterns across the region. In some areas, the use of water r

As defined by Standard 61, a total allowable concentration (TAC) is the maximum concentration of a nonregulated contaminant allowed in a public drinking water supply, and the single product allowable concentration (SPAC) is 10% of the TAC.

Abstract:

Plants produce a wide variety of natural volatile organic compounds (NVOCs), many of which are unique to each species. These compounds serve many purposes, such as fending off herbivores and adapting to changes in temperature and water supply. Interestingly, although NVOCs are synthesized to deter herbivores, many of these compounds have been found to possess several therapeutic qualities, such as promoting nerve stability, enhancing sleep, and suppressing hyperresponsiveness, in addition to acting as antioxidants and anti-inflammatory agents. Therefore, many NVOCs are promising drug candidate
