As I am
sure you all have discovered through our blog, soil contamination is
a global and complex epidemic. However in order to be aware and cause
a change, one must understand and be able to discuss the terminology
in regards to soil contamination. Below is some basic and common
terminology derived from the Environmental Protection Agency (EPA)
with their definition that is associated with soil contamination:
1. Contamination:
“Introduction
into water, air, and soil of microorganisms, chemicals, toxic
substances, wastes, or wastewater in a concentration that makes the
medium unfit for its next intended use” (www.epa.gov)
Contamination
can have many definitions and can be used in variety of ways and
contexts. However for this topic it is important that we define
contamination in regards to make the 'medium unfit for its next
intended use'. This distinction is important because this is what
makes soil contamination so adverse and harmful.
2. Conventional
Pesticides:
“Any
man-made chemical, which can be used to kill pests” (www.epa.gov).
Pesticides
are used to reduce pest, but they can be a pest themselves. When
these chemicals are used to treat farmlands they often get absorbed
into the ground or soil causing contamination.
3. Ground
Water:
“The
supply of fresh water found beneath the earth's surface, usually in
aquifers, which supply wells and springs” (www.epa.gov).
Ground
water is found between the cracks and crevasses of the ground or
soil. It is also source of drinking water. If our ground water is
contaminated so are the chances the soil or ground will be where that
water was located.
4. Herbicides:
“A
chemical pesticide designed to control or destroy plants, weeds, or
grasses” (www.epa.gov).
These
chemical are commonly used on farms while growing food. These
chemicals are also a n notorious contributor to soil contamination.
When farmers spray the chemicals on to the vegetables and fruits in
order to treat them, they are often absorbed into the soil.
