“Recent water testing had showed that 60 percent of the rivers and streams in that state [California] contained high levels of Prozac, Ritalin, and antibiotics. How could such contamination possibly have happened? Because people had dumped their excess prescription drugs into those bodies of water or had flushed them directly or through bodily waste into sewer and septic systems, where the chemicals then leeched into groundwater. I had to wonder what effects those drugs were having on fish and other wildlife and what levels of toxins might be accumulating in the tissues of people who consume the contaminated fish.”
