Pollution and depth of water
A water sample taken from deeper waters will contain less pollutant.
Rivers, lakes and oceans become polluted when foreign substances are released into these bodies of water before treatment to remove these contaminants has taken place. Our rivers and lakes are an important source of drinking water. They are also an important source of water for animals living in these habitats. When water is polluted, the entire ecosystem is affected. Polluted water is also unfit for agricultural and industrial use.
During heavy rainfall, pollutants in the surrounding catchment area are washed into lakes and rivers. These pollutants are a result of agricultural and industrial waste including fertilizers, insecticides, loose soil, organic material, chemicals and much more. When land is cleared for farming or development, the top layer of the soil is washed into the rivers and lakes. This causes a higher level of sedimentation in the water and affects the turbidity of the water.
In areas that are populated, water pollution arises in the form of domestic sewage, namely waste water discharged as a result ofhousehold activities such as washing clothes, showering or washing dishes. This waste water contains detergents, fat, grease and other household waste. The waste is discharged into the rivers through a network of drains and they eventually end up in the lakes or the ocean.
