Introduction Water is one of our most important natural resources. Water is used in different purpose such as domestic‚ industrial supply‚ transportation‚ recreation. However‚ nowadays‚ humans are continuously deteriorating rivers‚ lakes‚ and oceans through different agricultural‚ industrial activities. Abel (1996) states that water pollution defines as “the addition of undesirable materials into aquatic bodies” (p.1). This may cause physical‚ chemical or biological change in water‚ leading to different

(PEM‚ 2003). As stated in the EMB report‚ domestic wastewater discharges contribute highest to the BOD load as the lack of sewage treatment system allows more than 90 percent of inadequately treated domestic sewage to be discharged into surface waters‚ which contain bacteria and viruses that threaten human life. Geographically‚ data show that one-third (30 percent) of BOD generation comes from Metro Manila and Region IV alone‚ at 18 and 15 percent‚ respectively (PEM‚ 2003). Industrial wastewater

Effects of Water Pollution Image source: NASA Water covers 70% of the Earth’s surface and makes up over 60% of the human body. Water pollution affects marine ecosystems‚ wildlife health‚ and human well-being. The answer to solving pollution is to make changes in our daily habits and pay more attention to the types of products we consume. The following lists display causes of water pollution and the effects it has on human health and the natural environment. Causes of Water Pollution Sewage

fresh water is also becoming a scarcity. The limited availability of fresh water and its unequal distribution make water pollution a matter of great concern. Water pollution is generally localized and confined‚ making it more severe. The pollutants undergo many reactions and can become hazardous. 70 % of India’s fresh water is polluted‚ including several high altitude lakes. While water pollution is easier to study and manage‚ its control is highly complex and very costly. Water pollution
