Taking Action
Solutions & Filtration
Practical approaches to reducing microplastic contamination in our drinking water.
Advanced Filtration Technologies
Reverse Osmosis & Nanofiltration
Reverse osmosis (RO) systems are the most effective consumer-available technology for removing microplastics from drinking water. Nanofiltration membranes can also remove particles down to 0.001 micrometers. These systems force water through semi-permeable membranes that trap contaminants including microplastics, heavy metals, and many chemical pollutants.
- Removes particles >0.001 μm
- Also reduces heavy metals and chemicals
- Point-of-use or whole-home systems
- Requires filter replacement every 6-12 months
Municipal Water Treatment
Infrastructure Improvements
Municipal water treatment plants can remove a significant proportion of microplastics through existing processes including coagulation, flocculation, sedimentation, and sand filtration. However, effectiveness varies widely between facilities. Upgrades to include membrane filtration and advanced oxidation processes can significantly improve microplastic removal rates.
- Coagulation removes larger particles
- Sand filtration captures fibers
- Membrane upgrades improve removal
- Monitoring and standardization needed
Household Filtration Options
Consumer Protection
Several household filtration options can reduce microplastic content in drinking water. Activated carbon filters (including pitcher filters and faucet-mounted systems) can capture larger microplastic particles. For more thorough removal, under-sink reverse osmosis systems or countertop gravity filters with fine ceramic elements are recommended.
- Carbon block filters for basic protection
- Ceramic filters for improved removal
- Under-sink RO for comprehensive filtration
- Regular maintenance essential for effectiveness
Reducing Pollution at the Source
Prevention & Policy
The most effective long-term solution is reducing plastic pollution at its source. This includes policies banning microbeads in personal care products, improving waste management infrastructure, developing biodegradable alternatives to conventional plastics, and implementing extended producer responsibility programs.
- Microbead bans in cosmetics
- Improved waste management systems
- Biodegradable plastic alternatives
- Extended producer responsibility
