Mathematical modeling for solute transport in aquifer
Groundwater pollution may occur due to human activities, industrial effluents, cemeteries, mine spoils, etc. This paper deals with one-dimensional mathematical modeling of solute transport in finite aquifers. The governing equation for solute transport by unsteady groundwater flow is solved analytically by the Laplace transform technique. Initially, the aquifer is subjected to the spatially ...

Managing the invisible : understanding and improving groundwater governance
Groundwater is playing an increasingly important role in domestic, industrial and agricultural water supply. With the advent of the tube well and driven by the rapid growth of demand for agricultural and municipal water, annual global groundwater extraction has increased in recent decades from 100 km3 a year in 1950 to a current estimated use of about 800 km3 a year (Wada et al., 2010; Margat, ...

Simulation study of the sustainable utilization of urban water resources based on system dynamics: a case study of Jiamusi
To achieve sustainable utilization of urban water resources and sustainable social and economic development and to relieve the supply–demand pressure related to water resources in Jiamusi, a simulation model based on system dynamics theory is established to identify the feedback mechanism and the causal relationship among the factors affecting the sustainable utilization of water resources. ...

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 ...

Ensuring Water Quality in Africa
Water is essential for life, and “access to safe water is a fundamental human and, therefore, a basic human right.” With this statement and his address on World Water Day in 2001, United Nations Secretary-General Kofi Annan put a spotlight on what continues to be a global problem: clean water. This year completes the UN “Water for Life” international decade for action, ...

What is the textile effluent treatment?
Water is the most wonderful gift of nature. Water is most useful and abundant compound in the earth. Water is not only essential for human lives, animals, plant lives but also has a unique importance in industries. The textile industry uses water very intensively. Water is the main principle medium in the textile industry to apply dyes and various finishes. Thus the textile wastewater ...
