Is it safe to drink water from a supply system that runs near industrial facilities?

What's actually in it

Water utilities that source from rivers or groundwater near industrial facilities face an uphill battle on contamination. Plastic manufacturing, recycling, textile mills, and packaging plants release microplastic into nearby water. Treatment facilities can remove some but not all. The result is that communities on these systems get more microplastic per glass than similar communities farther from industrial sources.

This isn't something most people check. Annual Consumer Confidence Reports focus on regulated contaminants; microplastic isn't on that list yet.

What the research says

A 2026 study in J Hazard Mater tracked microplastics in a drinking water supply system near industrial facilities. The occurrence, source identification, and risk assessment all pointed to industrial runoff as the dominant contributor. Concentrations were several-fold higher than systems sourced from protected watersheds.

For households on industrial-proximity water, a home reverse osmosis system with a carbon prefilter removes most microplastic. Gravity filters (Berkey, Propur) also perform well. The filter lasts for months and handles the daily drinking water question. Use filtered water for cooking and ice too; not just drinking. For babies and pregnancy, this upgrade is one of the higher-impact kitchen changes.
