Pesticides are used to control pests and weeds in agriculture however, they unfortunately do not stay in the fields, but flow into bodies of water, eventually contaminating groundwater. Atrazine is such a pesticide; it is a herbicide commonly known as a “weedkiller” that decomposes relatively slowly in the environment.  The use of atrazine has been banned in the European Union since 2003, but in North America, it is still one of the most widely used pesticides, especially for corn, potato, and tomato cultivation. Thus, it can be found wherever conventional farming is practiced and has been identified in the drinking water of millions of people. Conventional methods of treating water cannot break down the herbicide without chemicals, which then themselves release toxic by-products.  Read more....
