water pollution causes what problem
Surface water may also be polluted with pathogens and waterborne diseases, which is usually the result of sewage leaks and runoff from animal factories. These viruses and bacteria that pollute the water may cause dangerous human health problems such as giardia, typhoid and hepatitis. Interestingly, one way to monitor for this type of pollution is checking the water for fecal coliform bacteria, which comes from the waste of people and other animals.
Clearing land for agriculture and urban growth often leads to water pollution. When soil is stripped of its protective vegetation it becomes prone to soil erosion. This leads to an increase in the murkiness of the water which can cause the following: 1  it can block the gills of fish; 2  bottom dwelling plants cannot photosynthesize as the sunâs rays cannot reach them; and. 3  there is an increase in disease as bacteria and viruses use the soil particles as a method of transportation.
