Stuck in an Abandoned School

When you begin to drink, at first the water tastes sweet. Then, a weird taste fills your mouth. Your instincts tell you to stop drinking, but you can't stop. You're just too thirsty. Your nose sniffs the air, and it smells like dirt mixed with chemicals. Suddenly, there is a searing pain in your stomach. You double over in a fit of coughs. As everything goes dark, you realize that since this school is abandoned, the water has probably been contaminated with soil, lead,and chemicals from the nearby sewers.
