					How is Mankind Contaminating Ground Water?
There are a number of amenities that man uses to better their lives. Chemicals and fuels are often
harvested, sold, and cast carelessly aside, setting the scene for ground water contamination.

Many of these chemicals should never be ingested. And yet, they are put in situations to silently poison
mankind every day.

Pesticides
Pesticides are sprayed across thousands of acres of food every year. Farmers use them to ensure a good
crop grows in that year.

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

Percolation is the slow passage of liquid through a filter. It drives the pesticides deep into the earth,
until it reaches water passages.

                                         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.

                                         These negative effects often don’t travel farther than the
                                         immediate farm area. It makes you wonder though, as pesticides
                                         are improved upon, and the soil grows more and more dense
                                         with these chemicals, how many of them will harm or mutate
                                         the crops that are shipped around the country?

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.

Fracking
Fracking is another problem that crops up from time to time. Fracking was created to make mining
natural gases safer and easier than ever before.

Machines drill holes thousands of feet into the ground, reaching deep enough to find pockets of fossils.
Once there, the gas is trapped within the fossils, making it difficult to mine.

Pressurized water and gas is shot down into the hole, creating fissures in the rocks and fossils so that the
natural gas can escape and be excavated. The water creates the fissures.
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.

Even with a groundwater map, it can be difficult to miss all of
the little off-shoots. Groundwater maps are accurate, but
they can’t capture everything, nor is it always easy to place
yourself in the exact right place to avoid drilling into it.

When chemicals are carelessly cast away, they are given the
chance to contaminate the ground water. A groundwater
map will show you that there is water everywhere
underneath the earth.

Pay careful attention to the chemicals your tossing out. When you carefully dispose of the chemicals
correctly, you go a long way to keep contaminants out.

Also be careful with the water you drink. Make sure you are receiving it from reliable cleansing plants.
