Contact Lens Becomes Latest Pollutant In Wastewater

The latest disposable causing a stir in the wastewater treatment world is the contact lens. Researchers from Arizona State University recently presented their findings at an American Chemical Society event showing that contact lenses flushed down the toilet or washed down the drain can pass through wastewater treatment plants and accumulate in sewage sludge. As sludge is often applied on land for disposal and fertilizing, macro- and microplastics from lenses enter terrestrial ecosystems.
