"Scientists are taking samples of the Hudson River this month to measure how much pharmaceutical pollution gets washed into the waterway during heavy rains and to pinpoint its source."

"Anti-depressants, blood pressure medicine, decongestants and other medicines have already been detected in the Hudson in preliminary samples. The latest round of testing is a larger sweep of the river at a time of the year when pollution overall is washing into the Hudson at a greater rate due to runoff and sewage overflows."
