Water pollution has been an increasing problem over the last few years. Pollution itself is when a substance or energy is introduced into the soil, air, or water in a concentrate. Pollution comes in many forms; agricultural, urban runoff, industrial, sedimentary, animal wastes, and leeching from landfills/septic systems just to name a few. These pollutants are very detrimental to the environment. Whether they are alone or combined with another form of pollution they are very harmful. Over the last hundred years the problems with pollution have been increasing with time. This is due to both the increase in human population, and the increases in technology we have made as a society. If we plan on having our resources here for many years to come we are going to have to make some drastic changes in the way we treat the earth, and these changes will have to start with our pollutants.
Agricultural pollution is a very big contributor to water pollution. Problems we see with agriculture are applications of fertilizers, insecticides, and pesticides. We have made vast improvements in the types of chemicals we are using, as to how environmentally friendly they are. Yet even today the effects of these chemicals are very harsh, for instance:
“The annual total output of pesticides in the United States is more than 2.5 billion pounds with 1500 active ingredients in some 45,000 products. Each year, approximately one billion pounds of pesticides containing more than 600 active ingredients, are applied to farms and gardens. Of this quantity, an estimated of 3.5 to 21 million pounds reach surface waters before degrading. (Rural Groundwater Contamination)
And not all of those 3.5 to 21 million pounds is removed in runoff, some of it leeches into the ground where it contaminates the groundwater supplies. This fact is very disturbing considering the fact that a large number of people that live in rural America. These p...
