For many homes and farms, water filters can be a solution to drinking water that may be contaminated by agricultural runoff. This article takes a look at this type of contamination and how water filters can be used to help solve this potential problem. The main issue associated with farm runoff, as it pertains to drinking water, comes from the chemicals that are used on farms: pesticides and fertilizers. These chemicals can find their way into underground aquifers when they seep through the dirt. They can also get into water sources by traveling along the upper soil, such as after a heavy rain, and entering rivers and streams.Those who live in rural areas face this potential type of water contamination more so than those who live in urban areas. The reason for this simple: rural homes and farms often get their water from private wells.Private wells are not required to be monitored for contamination levels as public water supplies are required. This means that some homes and farms may be at risk. It is also important to remember that ag runoff contamination can happen at any time and does not always present itself in the same place. This makes controlling this type of water contamination very difficult.The best way to think of this is to imagine a factory located on a river bank that pours its waste into the river. You can see this factory; you know where it is. Now imagine living in a rural area surrounded by thousands of acres of farm land. Contamination into the ground water can happen anywhere, and you most likely will not know where it is occurring or even
