are four different family of product in the bottled water market : * mineral water ; they are spring waters with specific properties such as medical treatment. They cannot be processed. * spring water ; they are naturally pure and from groundwater as mineral water. No treatment shall be given to them. They are on average three times less expensive than natural mineral waters. * Table water ; they designate tap water bottling. The treatments are tolerated here especially for gasification

spilled into a groundwater system? A) Gasoline and kerosene would float on the water table‚ but most pesticides break down chemically when they reach the water table. B) Gasoline and kerosene would float on the water table; ethyl alcohol would dissolve and disperse in the groundwater. C) Sulfuric and nitric acids would sink to the bottom of the aquifer; kerosene would accumulate as a layer just below the water table. D) All of the above toxic wastes would dissolve into the groundwater. Points Earned:

Some argue that even common MSW items such as newspaper pose a significant risk to water quality‚ while others argue that the effect of landfills on groundwater would be negligible if hazardous materials (e.g. motor oil‚ paint‚

There are several types of coal mining used throughout the world in different circumstances. Each has benefits in terms of production of coal‚ but they also have drawbacks in terms of environmental impact and safety risks. Nevertheless‚ coal production remains on the rise in many countries and does not appear to be subsiding any time soon. Mountaintop removal has become an increasingly popular method of coal mining‚ especially in the United States. It is mostly used in the Appalachian Mountains

Automobile Pollution. Automobiles can cause many different kinds of pollution in the environment. Air‚ health and groundwater pollution are of the most common. The reasons for these problems can be contributed to exhaust systems and light switches that are standard equipment on most cars today. Older and newer cars alike are equipped with a catalytic converter system. Which are supposed to convert hydrocarbons‚ carbon monoxide and nitrogen oxides into harmless materials emitted from the automobiles

The water came from outer space to Earth. The water was brought to the planet for the comets. The water has a different structure for each state (gas‚ liquid‚ ice). Liquid water has random molecules. On the other hand‚ the ice has a more stable structure. The different structure between ice and liquid water can explain why the ice has less density than liquid water. Temperature is responsible for increasing the dissolution of components‚ and electrical conductivity. Pure water is not a good conductor

Water Crisis and Water Management in Pakistan 1- Introduction Water plays a vital role in a country’s economy. Water has been critical to the making of human history. The earliest agricultural communities emerged where crops could be cultivated with dependable rainfall and perennial rivers. Simple irrigation canals permitted greater crop production and longer growing seasons in dry areas. Some of the problems faced by the world population are as below. • More than a billion people lack access

and congestion ➢ Soil contamination includes surface runoff‚ leakage into groundwater‚ liquid spills‚ wastewater discharge and littering. If toxins are spilled on the ground or if an underground storage tank leaks‚ soil can become contaminated. Well known contaminants include herbicides and pesticides. ➢ Water pollution is the contamination of water bodies such as lakes‚ rivers‚ oceans‚ and groundwater by human activities. It occurs when pollutants are discharged directly or indirectly

DEFORESTATION INTRODUCTION: Deforestation refers to the cutting‚ clearing‚ and removal of rainforest or related ecosystems into less bio-diverse ecosystems such as pasture‚ cropland‚ or plantations. Examples of deforestation include conversion of forestland to farms‚ ranches‚ or urban use. Thus‚ deforestation is an important issue to be discussed. It has adverse effects on each living beings’ life. Deforestation has become a huge concern in today’s life as there has been a rise in the decline
