A community gets its drinking water from a nearby lake. After many years, the company responsible for emptying the septic tanks in the community has shut down and a new company from out of town now empties the septic tanks. It would cost the company more money to haul the waste to their plant so the company has been dumping their trucks in a pit near the lake.
As the ball tournament begins to wind down, people begin to get sick. At first, three kids get sick and are taken to hospital. Then more and more people become ill. Over the next week, the number of sick people rises and includes almost everyone who was at the ball tournament and most of the community. There are no deaths but the final count of people who became sick is over 1000.
