Which objects allow humans to access groundwater? Check all that apply.
Masja [62]
<h2>Answer:</h2>

<u>The objects that allow humans to access ground water are:</u>

  • <u>A spring</u>
  • <u>a well drilled into an aquifer </u>
  • <u>a well drilled below the water table</u>
<h2>Explanation:</h2>

Access to ground water can be gained if we dig a well or use any source that can provide us an access below the water table. A water table is the level below which the ground is saturated with water. So above the saturation level we cannot gain access to water therefore we must go below it. A spring springs from ground below water table and the same thing occurs for well or an aquifer if it is below the water table..
