Summary Introduction

To describe:

The acid rain trends that is evident from the EPA data.

Introduction:

Acid rain is referred to the precipitation having a pH less than 5. These could be rain, snow or even atmospheric particles. The main reason for this is the combining of water with oxides of sulfur and nitrogen to make sulfuric acid and nitric acid, respectively.

Explanation of Solution

The EPA (Environmental protection agency) data graphs the amount of acid rain received in USA from 1980-2015. The graph clearly depicts that the amount of acid rain has decreased gradually over the years as a result of the strict laws against emissions.

Sulfuric acid has been the most commonly found acid in these rains in respect to its quantity as well as time. In 1980, approximately 17 million tons of sulphur dioxides precipitated. The precipitation gradually decimated to 3 million tons in 2015.

On the other hand, oxides of nitrogen became a part of the acid rain around 1995 with almost 6 million tons of precipitation. This came down to about 1.5 million tons in 2015.

Conclusion

The acid rains have reduced in the United States over the years from 1980-2015 according to the EPA data.
