Water institutional reforms in Morocco
ABSTRACT Using a teleological perspective and an analytical categorization of the history of water institutions in Morocco, this paper aims to review and evaluate the institutional reforms in the country in the light of the results and hypotheses presented in some recent literature on the subject. The review suggests that considering their overall thrust and direction, the institutional reforms ...

New Spanish regulation on groundwater protection
On 22 October it was issued Royal Decree 1514/2009 regulating the protection of groundwater against pollution and deterioration. The legal framework of this Royal Decree is formed by Directive 2000/60/EC (WFD) in particular Article 17, and Directive 20006/118/EC. The main objectives are to prevent or limit groundwater pollution and to establish criteria and procedures to assess their chemical ...

Unauthorized groundwater use: institutional, social and ethical considerations
In many areas of the world, particularly in arid regions or in areas experiencing population growth, there is increased competition over scarce water resources. This is likely to increase in the future due to continued population growth, urban expansion and the challenge of the impact of climate change on water resource availability. In this context, groundwater is likely to play a pivotal role ...

US groundwater protection regulations `not comprehensive enough`
Groundwater protection is the responsibility of everyone including the chemical industry. An energetic group of state and federal groundwater agencies, industry, environmentalists and other stakeholders, however, has made it a key area of their focus. The Ground Water Protection Council (GWPC) is a nonprofit Section 501(c)(6) organization dedicated to promoting and ensuring the use of best ...

An object-oriented development environment to optimally design cyclic storage systems
Cyclic storage system (CSS) is defined as physically interconnected and operationally integrated surface water and groundwater subsystems with full direct interactions between the subsystems. Mathematical development and implementation of a CSS model is very complex and all previous works are fully case dependent with a minimum possibility of generalization. This article proposes an integrated ...

A new frontier in Texas: managing and regulating brackish groundwater
The challenge of providing access to clean water is visible in Texas, where chronic drought coincides with increasing water demand. The 2012 Texas State Water Plan reports a 2,700 million cubic metres (MCM) gap between freshwater supply and demand in 2010, a number predicted to grow to 3,100 MCM by 2060. Due to the difficulty of reducing water demand, policy makers and water providers are ...

Climate change and biodiversity
On average, global temperatures on land have risen by 0.8 °C compared with pre‑industrial times. European land areas have warmed up more rapidly, however, increasing by more than 1.2 °C so far (IPCC, 2007), with a further increase of1.0–5.5 °C expected by the end of the 21st century (Christensen et al., 2007). Already southern Europe has experienced extremely dry weather conditions, with ...

Dr. Hargis presents at NGWA conference on ground water & environmental law
Dr. David R. Hargis will be presenting a paper titled, 'Wholesale Returns of Conjecture: Defensible Scientific Opinons in Court?' on Wednesday, July 21, 2005. The paper is part of a conference sponsored by the National Ground Water Association on the theme of 'Ground Water and Environmental Law.' The conference is to be held at the Wyndham Inner Harbor Hotel in Baltimore, Maryland, July 21-22, ...

The Federal Interim Groundwater Quality Guidelines
The Federal Interim Groundwater Quality Guidelines was developed by federal authorities to facilitate the assessment, remediation and risk management of federal contaminated sites which are under the funding of the Federal Contaminated Sites Action Plan (FCSAP). The guidelines are applicable in Canada until the time when groundwater guidelines will be developed. FCSAP was established to identify ...

Numerical simulation of drainage scenarios for lowering groundwater rise due to construction of a new barrage on the Nile River
The government of Egypt constructed a New Naga Hammadi Barrage (NNHB) 3.6 km downstream of the Old Naga Hammadi Barrage (ONHB). Upon construction, the water level raised by about 0.5 and 4 m upstream and within the river reach between ONHB and NNHB respectively. In this paper, a two–layer groundwater model was built using MicroFEM to study the groundwater rising problem. The model was used to ...

Oman: Guidelines for groundwater abstraction
Groundwater is a precious resource in Oman, which is designated “National Wealth” by Royal Decree. The concession agreement between Petroleum Development Oman (PDO) and the government gives PDO the right to explore and use groundwater. So far PDO has used groundwater only for maintaining camp operations. As the field is maturing, PDO is moving to enhanced oil recovery techniques, such ...

Regulatory Aspects of Direct Potable Reuse in California
Introduction California's water supplies are derived from a variety of sources, including local and imported surface water, groundwater, desalinated seawater, and recycled water. Water resources are becoming limited due to population increases, droughts, and reductions in imported water allocations. Furthermore, global climate change may exacerbate the problem in the future. Water recycling for ...

Relations between groundwater flow in an unconfined aquifer and seepage patterns in a closed-basin lake in glacial terrain
Groundwater dynamics affect lake water budgets, but its major factors and mechanisms still need clarification. This study evaluates the effects of surrounding groundwater flow on seepage direction and assesses factors that affect seepage flux in a closed-basin lake in northeastern Estonia – Lake Martiska. A piezometric map was used to determine directions of groundwater flow around the ...

Study: Coal-Fired Power Plants Are Polluting Groundwater
Environmental groups are pushing for tighter regulation and enforcement of EPA rules A new study shows that of the 265 coal-burning power plants it studied in the United States, 241 have dangerous levels of toxic metals in the groundwater around them, based on Environmental Protection Agency (EPA) standards. The figure, which comes to 91% of the plants, was derived only from plants that must ...

Fluoride removal from brackish groundwater by direct contact membrane distillation
The direct contact membrane distillation (DCMD) applied for fluoride removal from brackish groundwater is presented. The self-prepared polyvinylidene fluoride membrane exhibited high rejection of inorganic salt solutes and a maximum permeate flux 35.6 kgm−2 h−1 was obtained. The feed concentration had no marked impact on the permeate flux and the rejection of fluoride. The precipitation of CaCO3 ...

Statistische Aspekte bei der Auswertung von Grundwasserqualitätsdaten nach den Vorgaben der EU-Wasserrahmenrichtlinie (WRRL)
Abstract On 22. December 2000, directive 2000/60/EC, the Water Framework Directive, entered into force by being published in the official journal of the European Communities. Apart from comprehensive regulations in the field of water policy, this directive inlcudes provisions for the evaluation of groundwater quality data. The directive stipulates that data should be aggregated so that the ...

Groundwater governance: explaining regulatory non-compliance
This paper explores the non-compliance of water users through a case study of groundwater resources in the Gulf Islands (British Columbia (BC)) and the San Juan Islands (Washington). The research challenges two assumptions: that local regulations can easily incorporate scientific research, which in turn leads to sound on-the-ground management; that sound on-the-ground management translates into ...

Using solver to determine vertical groundwater velocities by temperature variations, Purdue University, Indiana, USA
Vertical groundwater velocities can be estimated based on directions of groundwater thermal gradients. Temperature-depth profiles were obtained from 12 monitoring wells at 3 different times of the year (Fall, Winter, and Spring) in West Lafayette, Indiana (USA) mainly on the Purdue University campus. Microsoft Excel Solver was used to match plots of groundwater temperature distribution in the ...

Common Treatment Train for Inorganics
A treatment train is the combination of different treatment technologies. A system diagram of a common treatment train for inorganics is illustrated below. Metal contaminated soil is treated using the combination of electrokinetics and phytoremediation. Electrokinetics is used to remove metals from deep soil and ground water. A low density direct current is applied to mobilize charged species, ...
