Water Pollution
Water pollution is a major global problem that requires ongoing evaluation and revision of water resource policy at all levels (from international down to individual aquifers and wells). It has been suggested that it is the leading worldwide cause of deaths and diseases, and that it accounts for the deaths of more than 14,000 people daily. In addition to the acute problems of water pollution in ...

Water pollution
Water pollution is a major problem in the global context. It has been suggested that it is the leading worldwide cause of deaths and diseases,1,2 and that it accounts for the deaths of more than 14,000 people daily.2 An estimated 700 million Indians have no access to a proper toilet, and 1,000 Indian children die of diarrheal sickness every day.3 Some 90% of China's cities suffer from ...

Abatement vs. treatment for efficient diffuse source water pollution management in terrestrial-marine systems
Marine ecosystems are affected by water pollution originating from coastal catchments. The delivery of water pollutants can be reduced through water pollution abatement as well as water pollution treatment. Hence, sustainable economic development of coastal regions requires balancing of the marginal costs from water pollution abatement and/or treatment and the associated marginal benefits from ...

Hazardous water pollution in China
The people of the Sahecun village in China are currently suffering severe health problems due to dangerously hazardous water. The water pollution has been caused by heavy metal, which is a result of a lead mine that closed down more than ten years ago. Villagers of Sahecun are experiencing dreadfully painful swellings all over their bodies. The heavily polluted water is also causing all kinds of ...

Application of water pollution detector
Background:The (nitrate) link between agriculture and water quality is nutrient abundance - I've always thought the main issue was with fertilizers. Excessive nutrient loss often leads to eutrophication of surface waters. This condition can lead to harmful algal blooms (HAB), which produce dangerous toxins and cause a drop in dissolved oxygen, killing fish in both marine and freshwater ...

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 ...

Projection pursuit cluster model based on genetic algorithm and its application in Karstic water pollution evaluation
A projection pursuit cluster model is used to resolve the problem of Karstic water pollution evaluation. First, the projection pursuit cluster model is stated. Then, a genetic algorithm is applied to optimise the projection direction of the projection pursuit cluster model, and the steps of the genetic algorithm are introduced in detail. Finally, a case study of Karstic water pollution evaluation ...

Water pollution control and strategies in Finnish pulp and paper industries in the 20th century
This paper discusses and analyses the evolution of the Finnish pulp and paper industries and their water pollution control strategies. The Finnish pulp and paper mills are mainly located along water courses in inland areas. The earliest documents on water pollution date back to the early 1900s. In spite of the remarkably good record during recent decades in water pollution control, it can be ...

Clean Water Act
The Clean Water Act (CWA) is the primary federal law in the United States governing water pollution. Passed in 1972, the act established the goals of eliminating releases of high amounts of toxic substances into water, eliminating additional water pollution by 1985, and ensuring that surface waters would meet standards necessary for human sports and recreation by 1983. The principal body of law ...

A study on synthetic regional environmental policies for utilising biomass resources
Due to the principles of mass balance, there is a trade-off between regional water pollution and global warming. However, local governments in charge of water pollution control usually try to reduce water pollution loads without thinking of the influences on global warming. This study aims to formulate a simulation/evaluation model that reflects material balance and evaluates the regional ...

Review and recommendations on a water pollution control framework for the pulp and paper sector in China
The pulp and paper sector has been a significant source of water pollution in China for many years. The Chinese government has made great efforts on water pollution control for the pulp and paper sector. While actively participating in various international treaties and conventions related to environmental management and pollution control in this sector, China has created a comprehensive ...

Storm Water Pollution Prevention Plans
Why Your Railroad Facility Needs One and What to do About It Did you know that that railroad facilities are subject to the Clean Water Act? This includes requirements to have a Storm Water Pollution Prevention Plan (SWPPP) in place to clarify how you will control pollutants in storm water runoff from your facility. A SWPPP will identify the potential sources of pollution and describe the ...

Water Pollutants Feminizing Male Fish
Hormones from birth control pills and other ’emerging contaminants’ can remain in wastewater effluent even after treatment A wide range of pollutants can contaminate freshwater systems, including physical contaminants such as plastics and microplastics, as well as chemicals, heavy metals, and other toxins. One class of pollutants, so-called “emerging contaminants,” ...

What are the biggest sources of water pollution?
Water pollutants can come in many different forms and can have dramatic impacts on fragile ecosystems and aquatic life. There are a huge number of different sources of pollutants and each can have very different levels of harmfulness and environmental impact. In order to explain this further this article explains why water pollution is such an issue,as well as some of its main ...

SNAP – Misconnected plumbing and water pollution
In the UK, approximately 300,000 homes have misconnected plumbing, sending grey and foul water directly into streams and rivers instead of sewage treatment works, polluting the waterways and damaging aquatic ecosystems. “The water industry estimates that misconnections cause a daily sewage discharge to streams and rivers equivalent to all the foul waste produced by a town the size of ...

Development and application of some renovated technologies for municipal wastewater treatment in China
China has been experiencing fast economic development in recent decades at the cost of serious environmental deterioration. Wastewater discharge, especially municipal wastewater discharge, and non-point pollution sources are becoming the major water pollution source and research focus. Great efforts have been made on water pollution control and a number of renovated technologies and processes for ...

Characterization of water pollution in drainage networks using continuous monitoring data in the Citadel area of Hue City, Vietnam
In the Citadel area of Hue City, drainage systems that include canals and ponds are considerable sources of fecal contaminants to inundated water during the rainy season because canals and ponds receive untreated wastewater. It is important to investigate the characteristics of hydraulics and water pollution in canals and ponds. At the canals and ponds, water sampling was conducted during dry ...

The effects of industrialisation on water quality and livelihoods in Lesotho
In Lesotho, some of the industrial wastewater discharges are being released untreated into the environment causing water pollution. This study investigates the extent and impacts of industrial water pollution in Lesotho and the associated effects on human livelihoods in the region. A combination of desk studies, in-field water sampling and socio-economic survey showed that industrial effluents ...
