Suppose a chemical was to spill onto the ground and get into the soil. The

chemical could contaminate (spoil) the groundwater. How do you think it could be

cleaned up?

To clean groundwater you must:

Explanation:

Eliminate the pollution source: An underground tank must be pumped dry and then dug out from the ground. A factory must be required to stop releasing toxic chemicals. Farms must be more careful about the chemicals they put on their fields.

Monitor the extent of the pollutant: Scientists test water in wells. Sometimes they drill wells to test water. They learn how the groundwater is flowing: how fast and in what direction. They study the contaminants in the groundwater. Then they determine where the contaminant plume is going.
