Water flows downhill and with it comes pollution that affects life in and along the rivers and the ocean. Scientists analyze mountain fish and coastal blue crabs to learn what's flowing downstream in North Carolina's waterways.

NGSS Performance Expectation: Construct an argument supported by evidence for how increases in human population and per-capita consumption of natural resources impacts Earth’s systems.

NC Essential Science Standard (Earth and Environmental Science): Predict the safety and potential potability of water supplies in North Carolina based on physical and biological factors.
