Water pollution is major cause of concern. There are several reasons for water pollution. Some of them include dump of wastes into water from factories and nuclear plants, nonpoint sources, fertilizers and pesticides used, mining, and air pollution.

1. Top 5 Reasons for Water Pollution
Water pollution is the contamination or adulteration of the water bodies, such as rivers,
lakes, seas, oceans, and ground water by number of human activities. Since water is
essential for all our basic needs, water pollution is a threat to us. Many communicable
diseases spread through unclean water, which even results in death. Although there are
different factors that contribute to water pollution, listed below are the most dangerous
causes of water pollution.
• Factories and nuclear plants play a major role in polluting the water. Wastes from
factories include toxins, such as lead, mercury, and other contaminants. These
chemicals are very harmful and can lead to serious health hazards.
• Nonpoint sources are one of the major causes of water pollution. Oil spills from cars,
trucks, and other vehicles on land get mixed with rainwater and runoff into streams
and lakes polluting them. These nonpoint sources are very difficult to monitor and
control, so it falls on each individual to make sure that their vehicles used does not
in any way contribute to further pollution. Proper maintenance of vehicles and oil
spill cleanup using eco-friendly products, such as Oil Gone Easy S-200 will help to a
great extent.
• Fertilizers and pesticides used in agricultural farms, homeowners lawns, and
roadsides are a threat to the natural water source. When runoff into local streams or
rivers or when drained down into groundwater, they contaminate the water
completely.
• Mining is another major reason for water pollution. Heavy metals and sulfur
components which are buried in the earth are exposed during mining and during
rainfall these toxic chemicals are exposed, which ultimately result in “acid rain
drainage”
• Surprising though it may seem, air pollution is also a cause of water pollution.
Pollutants, such as sulfur dioxide, nitric acid, and mercury, when deposited out of air
results in nutrient pollution and acidification of lakes.
