Description: A growing body of research has shown that microplastics are present in marine environments, within marine organisms, and in drinking water. In a survey that compared 150 tap water samples from both large cities and small towns on five continents, microscopic plastic fibers were found in nearly every sample. 94% of the water samples from the United States contained plastic microfibers. Microfiber pollution isn’t unique to just tap water, two recent studies have shown that microplastics are present in bottled water as well. One study found that 19 out of 20 bottled water brands analyzed were contaminated with microplastics. Consumers have a right to know what they are ingesting and SB 1422 will provide useful data on the presence of microplastics in drinking water. This bill will provide the public with information on the sources and ultimate destinations of plastic pollution.
