Answer to Question 1
Answer: Acid precipitation reaching the surface eventually feeds into the hydrologic system. Though some water falls directly onto lakes and rivers, the majority gets into them indirectly as soil or groundwater. Despite the indirect input into the surface waters, however, the water retains its acidity as it flows beneath the surface and eventually enters lakes and rivers. Through time, the surface water system becomes so acidic that it is inhospitable to life. At its worst, acidification can render lakes and rivers completely devoid of fish and aquatic birds.
Answer to Question 2
Answer: The AQI was created by the Environmental Protection Agency (EPA) to estimate the amount of certain pollutants present in the air for a particular location and time. High values over 150 reflect unhealthy levels and values less than 150 are consistent with healthier air quality.
