Understanding Ground Water Contamination

By Darrel Jefferson


Within one of the long finger like intermountain valleys that stretches down the epicenter of south central Idaho lies the lost rivers. The Big Lost and the Little Lost rivers of the Lost River Range of central Idaho are true to their names.

When most people think of the water that they need to drink every day, they will immediately picture falling rain, or perhaps the runoff from meted glaciers in the mountains. It is just a simple relive way of thinking about the issue that most have.

The problem is that some pesticides miss the plants. Those pesticides penetrate the soil over time, through a process known as percolation.

Groundwater, or subsurface water, is formed by natural processes of water seeping below the earth's surface. This water typically will come from rain water or water from rivers and lakes that soak through the soil to join the collective water supplies that are found underground.

Although the pesticides can be washed off of the crops so that they are safe for eating, getting them out of the water isn't as easy of a process. The problem is amplified when the pesticides are accidentally spilled or carelessly tossed aside.

This poses a danger to those who ingest it, as well as to the environment itself. No matter that the cause of the contamination or its chemical makeup, the fact of the matter is that such an event is going to have a heavy impact on the area where it occurs at.

Pesticides are only one kind of chemical. Mankind has mastered the creation and utilization of countless chemicals that improve quality of life. Many of these are either unnatural or not meant for the soil. So many of these end up in landfills and spilled over soil, contaminating the world.

Water is a very efficient carrier of these elements, and it distributes them quite quickly. The same kinds of problems occur from pesticide usage, power plants not being as careful as they should be, and more.

The last method of pollution has the potential to be the worst as hazardous liquids can pool on bedrock and create a sustained source of ground water pollutant as the water comes into contact with the reservoir of contaminant.

The sand keeps the fissures open to allow gas to continue to escape. Although the process is extremely helpful, it also assumes the risk of contaminating the ground water. Drilling the hole and continually working in it has the inherent danger of breaking into a natural stream underground. Exposing that stream to these gases contaminates it.

But because it only takes a small amount of pollutant to contaminate large amounts of drinkable ground water, this process is less effective as it requires pumping massive amounts of groundwater in order to remove small amounts of contaminant. The best way to prevent contaminating ground water then becomes containing and regulating the amount of pollution that is man-made and subsequently introduced into the ground water.

By demanding better stands and working with companies to clean up areas which have been hit hard by these issues, a better future can hopefully be achieved for all who are involved. Fresh water is the most valuable thing on earth, for without it, there cannot be any way to sustain life.
