The use of pesticides and herbicides for crop protection is expected to increase as the world population rises. As intensive farming methods continue to rely heavily on chemicals, the levels of persistent herbicides and pesticides prevalent in the environment also remains at dangerous levels.

The harsh reality is that agrochemicals, such as insecticides and germicides, can remain in the environment for many years. They can even enter drinking water sources where they pose a significant threat to human health.

Fortunately, public knowledge of the dangers of these chemicals is increasing pressure on agrochemical companies to remove pesticides and herbicides before the wastewater enters other water bodies.
