Microplastics are small plastic particles that can be found in drinking water sources, including surface water, groundwater, and bottled water. While the health impacts of microplastics in drinking water are not yet fully understood, there is growing concern about their potential effects on human health.

Microplastics can enter drinking water sources through a variety of pathways, including wastewater discharge, stormwater runoff, and atmospheric deposition. Once in the water, they can persist for long periods of time and be transported over long distances.

While there is currently no international standard for microplastics in drinking water, the World Health Organization is working to develop guidelines for assessing and managing the risks associated with microplastics in drinking water. In the meantime, there are a number of steps that can be taken to reduce the release of microplastics into the environment and to minimize exposure to microplastics in drinking water.
