Human Impacts on the Sustainability of Groundwater
Part I:
Time Period | Impact to Forest | Groundwater Levels | Saltwater Intrusion | Farming | Industrial development | Population |
1800s | Had very large forest areas | Plenty amounts of groundwater | Actually no incidences of salt water intrusion | Only had small scale farm land | Cities hadn’t formed yet and no industrial development | Was more people than the housing sector could accommodate |
1900s | Forest areas had decreased by half | Groundwater levels also decreased by half | By this time Oceans had traveled to the ground water | Had less farms but the ones they had was very large | Cities had exceptional growth and industrial development had begun | Large increase in people and housing |
2000s | Forest areas had decreased to a whopping 90% | Groundwater levels has been decreasing by 90% | The level of salt water intrusion into the underground water has increased a whole lot | Farm amounts remained the same but size decreased a little bit | The industrial development in the cities slightly increased | Housing sector has also been developing over a period of time |
Part II:
- Purpose
To find out if current human development does not change, will groundwater sustainability be affected by using an on-line laboratory chatroom? At CTU 0n-line they have many on-line labs where we can learn all about scientific experiments.
- Introduction
- Ground water is a critical component of the nation’s water resources. 25% of the earth’s total fresh water supply is stored as ground water, while less than 1% is stored in other water resources; such as: lakes, ponds, rivers and soil moisture. The other 74% of the fresh water supply is locked away in polar ice and also glaciers. (Alley 1999a)
- Hypothesis/Predicted Outcome
- If current human development does not change, I do believe that the groundwater sustainability will be affected by the actions of humans and they activities like; not disposing waste properly, agriculture threats, urbanization threats, oil leaks in the oceans and other natural contamination, as well as, surface threats in the water.
- Methods
I decided to use the following scientific methods to carry out this experiment:
- Observation
- Interview
- Case study and
- My Environment Science Course Material
- Results/Outcome
- Our groundwater has faced and will continue to face a decrease in the water levels because of human activities. Agricultural activities also will pose a great fear on water sustainability in our future.
- Discussion/Analysis
- If we don’t change the way we waste water and if human development activities don’t change we can run out of water. The results I found were what I excepting, because of all the oil spills, droughts, water boil alerts, and Low River and sea levels.
