Question

In 2004, tests were performed on the San Carlos Reservoir in Arizona to determine levels and distributions of some toxic metals. Cores of sediment were sampled and tested, and the scientists found that there were two time periods represented in the sediment by larger levels of copper than is recommended in sediment quality guidelines. What scientific investigation might these results lead the scientists to next?

Answer 1

a study on how copper affects aquatic life in a reservoir

Step-by-step explanation:

Answer 2

an investigation on how copper affects aquatic life in the reservoir

Step-by-step explanation:

It was observed that there were two time periods represented in the sediment by larger levels of copper than is recommended in sediment quality guidelines at the San Carlos Reservoir in Arizona

The next things that will be on their mind is to investigate on how copper affects aquatic life in the reservoir
