In 1969, a young man employed as a chemist by one of the South’s largest coal mining companies was routinely running lab tests on several substrates, including coal and water. The water samples, which were collected from ponds, streams, lakes, and wells near strip mine operations, were being analyzed for mineral content and pH. The number of water samples increased slowly for several months, from an average of 50 to 100 per week. The chemist and his only lab partner were able to accommodate the additional samples without much trouble. Suddenly, without warning, the number of water samples began increasing rapidly. Within 3 months they had increased to over 500 samples per week.
