Title: Human Impacts on the Sustainability of Groundwater

Instructions: You will need to write a 1-page lab report using the scientific method to answer the following question:

Part I: Using the time progression of industrialization and human development, fill in the data table below to help you write up your lab report.

Part II: Write a 1-page lab report using the following scientific method sections: 

Provide references in APA format. This includes a reference list and in-text citations for references used in the Introduction section. 

Give your paper a title and number, and identify each section as specified above. Although the hypothesis will be a 1-sentence answer, the other sections will need to be paragraphs to adequately explain your experiment.

Background Information

Planet Earth’s surface is over 70% water, but less than 1% of the water on Earth is considered accessible, usable freshwater for sustaining humans’ and other organisms’ lives. Of the accessible freshwater, approximately 99% is located in aquifers, natural underground water chambers, and other groundwater sources. Unfortunately, humans are depleting the aquifers faster than they can be recharged by the hydrological cycle. Therefore, three quarters of groundwater is considered nonrenewable.

Conditions

The main reason we using groundwater resources mainly for drinking and irrigation. As a result, this not only decreases an important source of freshwater—it also can cause pollution of that groundwater by saltwater intrusion. The recharge rate of groundwater is further hindered by land clearing and deforestation caused by human development. When land is cleared for human development, more flooding occurs, the transpiration rate (the amount of water that evaporates into the atmosphere from plants) is reduced, and rainwater is inhibited from adequately percolating (penetrating the soil) into the ground to allow for aquifers and groundwater to be recharged.

Impacts

Forty percent of the world’s food is produced via irrigation. As a result, if the current rate of groundwater usage continues, food production could be drastically reduced worldwide. This reduction in food supply would be detrimental in sustaining the projected worldwide human population of over 10 billion within the next 50 years.
