f the surface stream water in Sample Site 2 is contaminated by the entrance of groundwater, what is a likely source of the contamination

Hi. Unfortunately your question is incomplete and more information would be needed before it can be answered. However, I will try to help you as best I can.

To answer this question, you need to look at a map, or text that shows where this water is flowing. The components of the environment where this water is fluid will be the source of contamination. For example, if water is flowing through a pasture region, that pasture will be the source of contamination. If that water flows through a compost area, that compost will be the source of contamination.

the first phase of the government’s plan for settlement was building the transcontinental railroad. the railroad provided a way to bring settlers and manufactured goods west and ship their agricultural and mining produce east. the transcontinental railroad was an essential artery for rapid development of the frontier.

the second phase of the government’s plan was a liberal land distribution policy that made it possible for many people to homestead. with these two key elements—transportation and cheap land—the government rapidly achieved its goal of persuading people to move west, settle on farms, and push back the frontier.
