Pakistan Facing Deadly Water Contamination
Drought, overdraft of aquifers, and water contamination all contribute to an ever-increasing water crisis in Pakistan. 40% of deaths in country are attributed to critical pollution problem An estimated 40% of all deaths in Pakistan are caused by ingesting contaminated water — water filled with industrial waste, arsenic, diseases, and sewage. As recently as the late 1990s, ...

Water contamination - Types, sources, effects, solutions
Access to clean and safe water is a basic human right, but many communities face the challenge of lacking water, resulting in serious health risks, environmental impacts, and economic consequences. According to the United Nations, up to 1 in 4 people does not have access to safe drinking water. Out of those, a significant percent resort to using unsafe water. When water is considered unsafe to ...

Common Treatment Technologies for Explosives in Ground Water, Surface Water, and Leachate
Explosives-contaminated process waste waters can be subdivided into two categories: red water, which comes strictly from the manufacture of TNT, and pink water, which includes any washwater associated with load, assemble, and pack (LAP) operations or with the demilitarization of munitions involving contact with finished explosive. Despite their names, red and pink water cannot be identified by ...

Effects of a 20 year rain event: a quantitative microbial risk assessment of a case of contaminated bathing water in Copenhagen, Denmark
Quantitative microbial risk assessments (QMRAs) often lack data on water quality leading to great uncertainty in the QMRA because of the many assumptions. The quantity of waste water contamination was estimated and included in a QMRA on an extreme rain event leading to combined sewer overflow (CSO) to bathing water where an ironman competition later took place. Two dynamic models, (1) a ...

A comprehensive study on adsorption behavior of some azo dyes from aqueous solution onto different adsorbents
One of the major environmental problems is the existence of dye materials in water sources. This pollutant must be removed from water by appropriate methods. Although most of these methods are efficient for the treatment of waters contaminated with dye pollutants, they are very costly and commercially unattractive. Adsorption is one of the most popular methods for the removal of dye ...

Technology development for environmental problems of the Southeastern United States
The southeast has extensive natural resources, and limited population and industrial development. However it is one of the most rapidly growing regions of the USA, which leads to urban sprawl, development of wetlands and readily eroded beaches. Environmental regulations are generally at the minimum federal standard. Non-point source pollution from urban and agricultural areas and sedimentation ...

Treatment wetlands in decentralised approaches for linking sanitation to energy and food security
Treatment wetlands (TWs) are engineered systems that mimic the processes in natural wetlands with the purpose of treating contaminated water. Being a simple and robust technology, TWs are applied worldwide to treat various types of water. Besides treated water for reuse, TWs can be used in resources-oriented sanitation systems for recovering nutrients and carbon, as well as for growing ...

Distillation Process Can Yield Zero Liquid Discharge System
Many industrial applications produce liquid waste as a by-product of their process. As environmental regulations governing the disposal of industrial wastewater become more stringent, it's imperative that innovative wastewater treatment solutions are used to treat this waste and minimize the environmental impact of disposal. While numerous technologies exist to treat industrial wastewater, Zero ...

Industrial wastewater treatment
Industrial wastewater treatment covers the mechanisms and processes used to treat waters that have been contaminated in some way by anthropogenic industrial or commercial activities prior to its release into the environment or its re-use. Most industries produce some wet waste although recent trends in the developed world have been to minimise such production or recycle such waste within the ...

The mathematical modelling of total nitrogen contamination transport via groundwater from a sugar factory in Eskisehir, Turkey
In this study, mathematical modelling of the total nitrogen contamination transport in a porous medium was evaluated in order to determine the potential groundwater pollution caused by a sugar factory in the Eskisehir region of Turkey. Analytical solutions of mathematical modelling were performed to show graphically the distributions of contaminant concentrations. Multiflow computer programming ...

The impact of an open waste disposal site on soil and groundwater pollution
A study has been carried out of a waste disposal site, located in the valley of a small creek, 3 km south of Canakkale city centre. The surface area of the site was around 101000 square metres, and the total amount of waste deposited at the site since 1990 was approximately 1001000 tons. The major risks of the dump are its closeness to the university campus area to the south, the airport to the ...

Making MGP Wastes Beneficial
More than 11 billion gallons of coal tar were generated at MGP sites in the United States from 1816 to 1947. The types and quantities of waste discharged to surface waters from MGPs vary from site to site, and the disposition of several billion gallons is unknown and remains unaccounted for. Numerous locations in the United States have sediments and soils contaminated with wastes generated from ...

Proof That Bacteria Degrade Oil
There has been a lot of publicity and ‘noise’ around the ability of bacteria to degrade oil, especially following BP’s Gulf of Mexico incident. However little has been shown to prove that biological remediation is an effective means of treating oil contamination. Over many years CBIO have worked to develop a range of a microbial products that have proven to be able to ...

The Invisible Water Pollution Crisis
Around the world, water contaminants are damaging human health and local economies The World Bank, in its new report “Quality Unknown: The Invisible Water Crisis,” asserts that water contamination is already a problem. But it is one that will only worsen in the future with global warming. The report foregrounds the fact that not all dangerously contaminated bodies of water will ...

Benefits to groundwater quality by diverting construction and demolition wastes from landfills
The objective of this report is to evaluate the effects to groundwater by diversion of solid wastes from landfills. The focus is directed to the diversion of solid wastes from construction and demolition landfills associated with deconstruction and demolition projects. The environmental benefits of this diversion are discussed including groundwater contamination issues. Additionally, diversion ...

Fighting soil contamination with XRF
Soil contamination Complying with new environmental regulations is a fast growing concern for companies and local officials tasked with ensuring that industries reduce pollution and clean up after themselves. It’s a particularly challenging issue when it comes to soil contamination It’s not always easy to detect as it silently contaminates crops and the ground water supply. XRF ...

Contamination of groundwater and the risk to human health
Groundwater is a major source of drinking water in many parts of the world. In industrialised countries, there is increasing concern that groundwater reserves are being contaminated by industrial effluents and the chemical pesticides and fertilizers used in intensive farming. This paper compares some of the existing guidelines for acceptable concentrations of certain common contaminants in ...

What classifies as water pollution and why is it an issue?
The UN declared 2005-2015 as the International Decade for Action ‘Water for Life’. Yet each day thousands of people still die as a result of contaminated water. This does not even take into account the millions of organisms that perish every year thank to polluted water sources. Water pollution is a huge issue that is made more so by the fact that unfortunately, water is easily ...
