Drinking Water Supply System

Drinking water supply is essential for public health, quality of life, sustainable development of economic activity, and environmental protection. In this context, it is important to ensure continuous improvement of all stages of processes to guarantee water quality and safety [1]. The main objectives of the study are: -development of an integrated method and probable risk analysis for a drinking water supply system; -risk assessment of contamination of raw water with nitrate [2].

Huangpu River

Water quality has deteriorated in recent years in Shanghai, China. More species of hazardous organic contaminant have been discovered. In developed area such as Shanghai, water pollution is more and more severe. Water quality of rivers in Shanghai territory falls into category Ⅲ~IV, which does not meet drinking water source standard. Huangpu River, the mother river of shanghai native, which provides nearly 80% of the water supply for downtown Shanghai, is facing imminent severe water pollution problem.

Drinking Water Supply System

Abstract. Developments such as climate change and a growing demand for drinking water threaten the sustainability of drinking water supply worldwide. To deal with this threat, adaptation of drinking water supply systems is imperative, not only on a global and national scale but particularly on a local scale. This investigation sought to establish characteristics that describe the sustainability of local drinking water supply. The hypothesis of this research was that sustainability characteristics depend on the context that is analysed, and therefore, a variety of cases must be analysed to reach a better understanding of the sustainability of drinking water supply in the Netherlands. Therefore, three divergent cases on drinking water supply in the Netherlands were analysed. One case related to a short-term development (2018 summer drought), and two concerned long-term phenomena (changes in water quality and growth in drinking water demand). We used an integrated systems approach, describing the local drinking water supply system in terms of hydrological, technical, and socio-economic characteristics that determine the sustainability of a local drinking water supply system. To gain a perspective on the case study findings that are broader than the Dutch context, the sustainability aspects identified were paired with global aspects concerning sustainable drinking water supply. This resulted in the following set of hydrological, technical, and socio-economic sustainability characteristics: (1) water quality, water resource availability, and impact of drinking water abstraction; (2) reliability and resilience of the technical system and energy use and environmental impact; (3) drinking water availability, water governance, and land and water use. Elaboration of these sustainability characteristics and criteria into a sustainability assessment can provide information on the challenges and trade-offs inherent in the sustainable development and management of a local drinking water supply system.

Drinking Water Supply System

Three Gram-positive, rod-shaped bacterial strains were isolated from the drinking water supply system of the Hungarian capital, Budapest. Phylogenetic analysis on the basis of 16S rRNA gene sequence comparison revealed that the isolates represented a distinct cluster within the clade of the genus Nocardioides and were most closely related to Nocardioides pyridinolyticus OS4T, Nocardioides aquiterrae GW-9T, Nocardioides sediminis MSL-01T and N. hankookensis DS-30T. The peptidoglycan based on ll-2,6-diaminopimelic acid, the major menaquinone MK-8(H4), the cellular fatty acid profile with iso-C16 : 0 and anteiso-C17 : 0 as predominating components and the DNA G+C content of 71.4 mol% (strain 1RaM5-12T) were consistent with the affiliation of the isolates to the genus Nocardioides. Because of differences in physiological characteristics, matrix-assisted laser-desorption/ionization time-of-flight mass spectra of protein extracts, PvuII RiboPrinter patterns and 96.1 % 16S rRNA gene sequence similarity between strain 1RaM5-12T and its closest phylogenetic neighbour, N. pyridinolyticus OS4T, a novel species, Nocardioides hungaricus sp. nov., is proposed. The type strain is 1RaM5-12T (=DSM 21673T =NCAIM 02330T).
