Matching oil in water analyses with regulatory methods
While the amount of oil in water is highly regulated, it can also be a challenging measurement. It is complicated by the fact that oil conies in many forms and the measurement is defined by the particular regulatory method. When EPA 1664 is the regulatory method, the "oil" is anything that is extracted into hexane and remains after the hcxanc has been evaporated and appears as weight. In regions ...

Impact of globalisation on biodiversity conservation
Biodiversity is generally described at three levels – diversity of ecosystems, diversity of species, and diversity of genes. Biodiversity is both a scientific and a political concept, embracing a trinity of globally-agreed objectives such as conservation of biodiversity, sustainable use of biological resources, and equitable sharing of the benefits arising from this use. This paper describes ...

Matching Oil in Water Analyses with Regulatory Methods - Case study
When analyzing oil and grease in water while out in the field, it is important to use an EPA approved method and equipment. While the amount of oil in water is highly regulated, it can also be a challenging measurement. It is complicated by the fact that oil conies in many forms and the measurement is defined by the particular regulatory method. When EPA 1664 is the regulatory method, the "oil" ...

Introduction
Different definitions of water governance will be reviewed and the question will be asked: Why is water governance important? Subsequently, some theoretical insights will be reviewed concerning the factors influencing successful water governance. A theoretical framework will be provided. Currently, water governance structures are often not able to deal with these factors, which require reform and ...

Analysis of the net water loss in the main reach of the Yellow River
In this study, several methods were employed to identify water losses in several reaches of the Yellow River. Then, a method for calculating the net water loss was developed. Also, annual, decadal and seasonal net water losses were analysed for the main reach of the Yellow River. Net evaporation, seepage and transmission per unit length of the river were estimated. The results showed that in the ...

Monitoring of waterintake from Panama canal - Case Study
APPLICATION Monitoring of a water intake to detect oil con-tamination. CUSTOMER Panama Canal PROBLEM The constant transit of vessels results in a high risk of collisions with the banks or structures of the canal and produce an accidental spill of oil. This would compromise the supply of potable water for consumption and general uses in the Canal Zone. ...

Different cost-benefit analyses in The Netherlands for the European Water Framework Directive
Since 2005, several cost benefit analyses have been performed for the European Water Framework Directive (WFD) in The Netherlands. These analyses had in common that they were meant to support the decision-making process by informing policy makers and making the trade-offs as transparent as possible. The analyses also anticipate questions from the Dutch Parliament. Nevertheless, each time the ...

Yucca Mountain Project, Nevada -
Wells J-12 and J-13 are located in Area 25 of the Nevada Test Site near Mercury, Nevada. These wells supply potable water for the Yucca Mountain Project. Water-quality analyses revealed that arsenic concentrations exceeded the new maximum contaminant level (MCL). Before choosing a technology, the site manager, Bechtel SAIC, contracted with Dr. Dennis A. Clifford, University of Houston, and a ...

On eco-efficiency and sustainable development in Estonia
The basic idea of sustainable development is a firm understanding that all resources, renewable as well as non-renewable, are limited. Human activities should not exceed the buffering capacity of the earth's ecosystems and the replenishment potential of material cycles. Use of non-renewable, mainly mineral, resources should be kept at the minimum possible level, postponing the depletion of ...

The role of investment arbitration in water services governance
The flux of foreign investment into the water industry that took place over recent decades had a significant impact on the relationship between water companies and states. The creation of a global network of international investment agreements also altered the method of adjudication of possible disputes between the parties. The emergence of global water markets and the advent of ...

Using smart meters to identify social and technological impacts on residential water consumption
Studies have shown that householders' perceptions of their water use are often not well matched with their actual water use. There has been less research, however, investigating whether this bias is related to specific types of end use and/or specific types of socio-demographic and socio-demographic household profiles. A high resolution smart metering study producing a detailed end use event ...

The role of proximity in problem identification: risk of water scarcity in Texas
This project seeks to determine whether proximity to major water sources (e.g. rivers or lakes) is associated with the public's perception of water scarcity. From a theoretical perspective, this project will aid our collective understanding of problem identification. From a practical perspective, this relationship could help inform decision makers about where support or resistance to a water ...

Water consumption in public schools for the city of Bologna, Italy
For most buildings considered to be of a public non-residential type there are insufficient published data to establish and compare the theoretical standards with actual consumption data. Therefore, water consumption per user in non-residential buildings is still a very complicated issue for engineers and designers involved in analysing water demand and water management. This is why linking ...
