"California scientists hope studying 180 black mussels pried from algae-covered rocks in San Francisco Bay will provide clues into how many drugs and chemicals are polluting waters across the nation."

Note "how many," not "if." How many? They're not just talking about oil spills and other standard pollutants, they mean like birth control and hand sanitizers. And it's not just California, it's every coast in America. These chemicals are so pervasive that they have even been found in breast milk, for crying out loud. Unfortunately, I am on city water. I do use a filter, but am not deluded that it does anything other than remove the most common chemicals.
