A chemical plant releases untreated wastewater with high levels of mercury into a river. The plant is near the river, and scientists find that the mercury comes directly from the plant's discharge pipe. The mercury levels in the water downstream are higher than safe limits.
What is the best way to find and control this pollution?
A. Using computer models to track water flow
B. Installing sensors to measure pollution in different spots
C. Checking the pollution from above with drones
D. Testing animals for mercury contamination
Installing sensors to measure pollution in different spots
(B)
After a heavy rain, scientists test the water in a river and find high levels of nitrates and phosphorus. The source of the pollutants is traced to runoff from farms, lawns, and cities, but it’s impossible to identify one specific source. This runoff is causing algae growth, lowering oxygen levels, and harming fish and other aquatic animals.
What is the biggest challenge in controlling this type of pollution?
A. The pollution can be traced directly to a single location.
B. The pollutants come from many different sources, making it hard to control.
C. The pollution only happens during dry weather.
D. The pollution naturally disappears over time.
The pollutants come from many different sources, making it hard to control.
