6 types of water pollution

posted in: Article, Blog, Web | 0

Water pollution is the contamination of water bodies like lakes, rivers, oceans, aquifers and groundwater. Water pollution occurs when pollutants are directly or indirectly discharged into water bodies without adequate treatment remove harmful compounds.

Surface water pollution

Hazardous substances coming into contact with surface water, like rivers, lakes, lagoons and oceans, and dissolving or mixing physically with the water is called surface water pollution.

Oil Pollution

An oil spill is the release of a liquid petroleum hydrocarbon into the environment, especially marine areas, due to human activity. Oil spills usually have only a localized affect but can spread.

Chemical Water Pollution

Many industries and farmers work with chemicals that end up in water. These include chemicals that are used to control weeds, insects and pests. Metals and solvents from industries can pollute water bodies.

Ground Water Pollution

When humans apply pesticides and chemicals to soils, they are washed deep into the ground by rain water. This gets to underground water, causing pollution underground.

Thermal pollution

Thermal pollution is the rise or fall in the temperature of a natural body of water caused by human influence. Thermal pollution, unlike chemical pollution, results in a change in the physical properties of water.

Agricultural Pollution

Sediment soil washed off fields is the largest source of agricultural pollution in the United States. Farmers may utilize to reduce runoff flows and retain soil on their fields.


Securewaters designed a early warning monitoring solution that detects the effect that these 6 types of pollution have on the algae that are present in surface water: the AquaSentinel™. This sensor sends alerts whenever it detects a threat in the surface water which enables governments or industry to take the required action. All in real-time. Read all about how it works
