7.1 Introduction
Maintaining and improving the quality of soil, water, and air resources rep-
resent some of the greatest challenges standing before our society today.
Pollution from a variety of sources, such as oil and chemical spills, pesti-
cide and fertilizer runoff, abandoned industrial and mining sites, as well
