effort to build or even maintain access to water will increase. And water’s importance to political and social stability will only grow with the crisis. WATER POLLUTION Water pollution is the contamination of water bodies (e.g. lakes‚ rivers‚ oceans‚ aquifers and groundwater). Water pollution occurs when pollutants are directly or indirectly discharged into water bodies without adequate treatment to remove harmful compounds. Water pollution affects plants

multiple weeks without being able to use the toilet‚ take a shower or having running water? There is a drought in California and the water is being fought over by the citizens and the farmers. California should regulate the amount of water taken from aquifers so everybody can take showers‚ use the bathroom and wash their hands. Consequently‚ “Officials say at least 1‚300 people have lost their water in and around East Porterville‚ nearly three hours’ drive north of Los Angeles‚ making the town’s residents

of laterite‚ brick and stone. Since the mid-1970s trial sections ofbituminous-surfaced low-volume roads have used laterite in place of stone as a base course. Thick laterite layers are porous and slightly permeable‚ so the layers can function as aquifers in rural areas. Locally available laterites are used in an acid solution‚ followed by precipitation to remove phosphorus and heavy metals at sewage treatment facilities. Laterites are a source of aluminium ore; the ore exists largely in clay minerals

Most water pollutants are eventually carried by rivers into the oceans. In some areas of the world the influence can be traced hundred miles from the mouth by studies using hydrology transport models. Advanced computer models such as SWMM or the DSSAM Model have been used in many locations worldwide to examine the fate of pollutants in aquatic systems. Indicator filter feeding species such as copepods have also been used to study pollutant fates in the New York Bight‚ for example. The highest toxin

Currently‚ with drought conditions across the nation‚ water is being trucked and piped out from the Ogallala water aquifer‚ which provides 90 percent of the water used for agriculture in the Midwest. Due to this the water is being depleting in many areas of the aquifer‚ increasing the chances of another major water shortage in the near future. The aquifer is being depleted by more than just people needing to shower and cook in California‚ Nevada‚ and Oregon‚ but also the amount of crops

Even though it is not a very reliable source since it hardly ever rains in California we can slowly collect the water to refill our aquifers back up. We can do this by capturing the rainwater and letting it percolate back into the ground. This is not a very fast way to get water but‚ we are not

Managing Water Supply Freshwater * Only 3% of the Earth’s water is fresh water‚ 97% is sea water. * Only 1% of the total amount of water is available for human use. Water as a scarce resource Reasons for scarcity: - Due to increasing demand as annual global use of water has increased 7 fold. -Uneven distribution of precipitation -Climate change leads to disturbances to water cycle - Deforestation leads to higher surface runoff which causes less clean water. - Poor or improper farming practices

The factors used to determine the level of water stress that hampers economic development and human health are population growth‚ increased affluence‚ and expansion of business activity‚ rapid urbanization‚ and climate change‚ depletion of aquifers‚ pollution and water protection. The water cycle itself is important in understanding how this precious natural resource renews itself‚ but as mentioned earlier fresh surface water (or ground water) is what keeps life going.
