Quizplus · Accepted Answer

By determining which wells show the toxic substance and which do not, we can track the flow of water to identify potential sources of contamination. This can be done by analyzing the geological and hydrological data of the area, including the direction and speed of the water movement, and the location of potential sources such as landfills, factories, or agricultural fields. By doing this, we can narrow down the potential sources and work towards removing or reducing the contamination. Options A and D are either impractical or insufficiently precise, while option B assumes that chemical factories are the only possible source of contamination.
