As many know, drinking water is a nonrenewable resource, and as such, we must care for and it is a necessary good for our lives, as well as for all living things, despite the increasing water Pollution is increased by neglect, and the little care that we have about it.

Doing our bit for the issue, we have prepared a brief overview of what the issue is to gain an understanding of the various forms of pollution problems and which are now detected, and to better understand why they take certain preventive measures. Read the rest of this entry »

The 7 percent of all deaths and illnesses in the world is caused by the water supply, inadequate sanitation and hygiene (UNDP, UNEP, World Bank and WRI 1998). About 5 percent can be attributed to air pollution (Holdren and Smith 2000). Each year, environmental hazards kill 3 million children under five (WHO 2002). According to current estimates, between 40 and 60 percent of these deaths are due to acute respiratory infections caused by environmental factors, especially particulate emissions from solid fuel use (Smith, Corvalan and Kjellström 1999).

There are a number of water contaminants that can be classified in many different ways. One possibility is to group largely utilized in the following eight groups:

#Pathogen.

Are the different types of bacteria, viruses, protozoa and other organisms that transmit diseases such as cholera, typhoid, gastroenteritis different, hepatitis, etc. In developing countries diseases caused by these pathogens are one of the main reasons for premature death, especially of children.

Normally these bacteria get into the water in the feces and other organic debris produced by infected people. For this, a good index to measure the health of the waters in regard to these microorganisms, is the number of coliform bacteria in water. Read the rest of this entry »

No doubt one of the biggest problems facing many people today (whether developed or underdeveloped, although it is true that I have never liked this term) is water pollution.

Mainly because as we know, water is virtually essential for life, and so the contamination can be very negative for both economic and social development of the people or communities living close to the polluted site.

It is true, as argued by many experts, the water pollution caused by human activities is an important environmental phenomenon, which begins to produce since the first attempts of industrialization, to transform it into a problem as common as widespread.

For the start of the one called industrial revolution in the early nineteenth century, the production processes of this period required the use of a large amount of water for processing raw materials, while effluent production processes such discharges were then in natural water channels, with their waste pollutants concerned.

Freshwater pollution problem known since antiquity. One of the first historical evidence is the story of Scripture on one of the ten plagues of Egypt, which describes the transformation in “blood” from the Nile river water, a biological phenomenon because of contamination caused by microorganisms.

With increasing population and the emergence of industrial water pollution of rivers, lakes and even ground water continues to rise. Pollution caused by domestic and industrial waste, deforestation and land-use practices, significantly reduce the availability of water that can be used.
