Sources Of Water Pollution

Water is regarded as polluted if certain substances or conditions are present to such a point that water cannot be used for specific purposes. Water is defined as the presence of excessive amounts of pollutants in water in such a way that water is no longer suitable for drinking, bathing, cooking and any other uses. Pollution is said to be the introduction of contamination into the environment. Pollution is created by industrial waste, commercial waste, agricultural activities and human activities such as transportation (Owa, 2013).

Sources of water pollution

According to (Owa, 2013), water pollution arises from various activities such as sewage, leakages, high population density, oil spilled, industrial waste dumped into waters, flooding

Bacteria and virus that carry diseases are carried into surface and ground water. Drinking water is affected by such viruses and bacteria and as a result life is threatened. The direct damage to plants and animals due to pollution also affect human health. Plants nutrients such as nitrogen and phosphorus that supports the growth of aquatic plant life could be in excess causing algal gloom and excessive weed growth. This makes water to have an unpleasant smell, taste and undesired color. According to (Ajibade, 2004) the consumption of water from lakes, streams and rivers may cause waterborne diseases such as bacillary, dysentery, guinea worn, hookworm, typhoid, cholera and epidemic which constitute the root cause of acute morbidity and mortality especially in children. The research further indicated that many sicknesses and death occur due to infectious diseases which are related to open water supplies in tropical developing

These chemicals enter into the environment through pesticides applications, as byproducts of industrial process and as household waste such as cleansers and pharmaceuticals. Chemicals in water are a health hazard to living organisms. Chemicals in water can be naturally occurring or introduced by human activities. Water contains chemicals such as fluoride, arsenic, lead, chlorine, petrochemicals and chemicals from recreation use. Fluoride in water is important for protecting teeth and strengthening bones, but at higher levels fluoride can cause negative effects on the health of humans. Arsenic occurs naturally, high concentrations of arsenic in water can cause sicknesses in human beings. Many people who drink water contaminated from arsenic suffered arsenic skin lesions. Chlorinate solvents are also considered to be a problem in surface water. Chlorinated substances enter into water through discharge from contaminated sewage, factories and pesticides from industries and fertilizers form agricultural
