So how many people can the aquifer support? In reality,
most people do not depend solely on water from the aquifer.
A combination of surface water and groundwater is used
to support the population. Also, variations throughout
the huge extent of the aquifer make it difficult to
estimate the total volume of water humans could actually
pump from it. Over time, variations in climate, population
growth, water use, and other variables will also alter
the actual length of time that the aquifer can support
people's water needs.
In order to come up with an estimate of the number of people an aquifer could support, some assumptions must be made. Use the assumed values below, or come up with your own to calculate an estimate that answers the investigation question.
10. Calculate an estimate of the number
of people who could get all the water they would need
all their lives from the Denver Basin aquifer system.
The aquifer contains 15 trillion gallons of water.
People use 150 gallons of water per person per day.
Humans live eighty years.
