Someone could test this: - Measure bottle water microplastic contents. - Measure tap water microplastic contents. - Put tap water in bottles and graph amount

Someone could test this: - Measure bottle water microplastic contents. - Measure tap water microplastic contents. - Put tap water in bottles and graph amount of microplastics vs days. If you want to measure e.g. 10 days, fill and leave 10 * N bottles resting, then open and measure N bottles everyday. - If it can be demonstrated that the plastics come from the bottle, repeat with other batches where every day the bottles are shaken vs still, or under the sun vs shadow, etc. to see what affects them the most.
