Answer 1

The geologists working for the Environmental Protection Agency would most likely track pH levels in surface waters to determine the effects of acid rain on aquatic ecosystems. To track pH levels, they would use a device called a pH meter or pH indicator strips. They would collect water samples from different sites across the country and measure the acidity or alkalinity of the water by measuring the concentration of hydrogen ions. By monitoring pH levels over time, geologists can assess the impact of acid rain on aquatic ecosystems and identify areas that may require further investigation or remediation. Therefore, the correct answer is "pH levels."
