Challenge of ensuring sustainable and clean groundwater

Author: Sharma, Dinesh C.

Keywords: Groundwater
Groundwater recharge

Issue Date: 2015-07

Publisher: National Council of Science Museums, Kolkata

Description: Water being drawn from a well was once precipitation that fell onto the Earth's surface. It seeped into the ground and, over time, occupied the porous cracks, spaces, and pores of the underground rock. People drill wells into rock formations that are permeable and porous enough to hold significant amounts of water and pump water to the surface for use. Naturally, big particles that can be found in streams, such as leaf chunks, bugs, and bubble-gum wrappers, will not be seen in groundwater. So, yes, big particles are filtered out. But groundwater can contain other items that you can't see. Some are naturally occurring and some are human-made substances. Groundwater can contain hydrogen sulphide (makes the water smell like rotten eggs) or other naturally occurring chemicals. Groundwater also may contain petroleum, organic compounds, or other chemicals introduced by human activities.

Description: Includes bibliographical references.
