Water Contamination, Conservation, and Prevention Methods
Kristopher Parra
What I covered last time.
Agricultural Pollution
Excessive pesticide and fertilizer use results in residue in the soil.
Animal excrement also poses problems when disposed improperly.
Accidental runoff in our water sources can end up in our drinking water.
Pesticides prevent pests from destroying crops.
Agricultural pollution is not something to be proud of but is necessary to increase yields of crops to feed our world as human population continues to grow.
Many GM crops exist and are engineered to be more sustainable and efficient in growth.
Efforts are being made to reduce pollution wastes being released.
Water Depletion
Why agricultural pollution may never be completely eliminated...
Companies need to make enough income to be financially successful. Some do try to be economically friendly. But to avoid financial failure income may be more important than it should be.
They do try to use better fertilizers and compost and better techniques but some are very costly.
Our lifestyle of living will be affected if we limit contaminants to an extreme.
Humans are a destructive force and new contaminants will appear as we make advances and create new pesticides/herbicides etc.


Recent rapid growth in population and vast improvements in technology and the growth has resulted in increases of contaminants polluting the soil and waterways from various sources.
Chemical contaminants are a rising concern and threat to our drinking water.
Water depletion is increasing dramatically and efforts need to be taken to slow down the rates.
Stopping production is not possible but setting limits may help.
How much contaminants can be released before it is too much? How much water can be conserved to prevent or slow water depletion rates?
Groundwater supplies nearly half of the populations drinking water.
Over 50 billion gallons are used daily for agricultural use.
Very good example of water depletion is the Ogallala Aquifer.
Provides freshwater for roughly 1/5 of the wheat, corn, cattle, and cotton production in the U.S.
Drought is a main concern.
Water depletion deteriorates water quality.
Water conservation is important. But crops need water and we need crops.
Rapidly growing population numbers results in more crops being needed.
Genetically develop drought resistant crops may help but are difficult to engineer.
We can slow the use of groundwater but as population continues to increase we are eventually going to overuse our resources.
If we were to stop the use of these nearly depleted aquifers and sources of groundwater, think how it may affect our livelihood in this point in time.
Companies and Water
Conservation
Possibility of Chemical Contamination Reduction
From a company point of view further research when using new chemicals is possible but the costs may not prove efficient. And some items may see an increase in price.
Not all contaminants are known until they react with the environment. In order to make improvements to our well-being some risks have to be taken.

Against
Our drinking water supply is as clean as ever. Especially after the Milwaukee incident in the 90's . Drinking water is definitely safe now.
Even if we discover all contaminants today, more will be developed in the future. We are always making advancements and some may have repercussions.
Key Points To Think About
Even if we found all of today's harmful contaminants, what would happen when we make future advancements and create new harmful compounds? Advancement in technology comes with a price.
Our current lifestyle uses more modern technology than you may realize. Think how that may be affected if we were to stop or limit the use of groundwater as a resource dramatically or other water sources.
Water conservation is important but we need crops as a food source and crops need water. So where do we draw the line and start to conserve water in the agriculture field?
The human population has continued to grow at alarming rates. Whats going to happen when we need even more water than we do now?
