Tap Water Safety and Regulations
- Most U.S. tap water is safe, regulated by EPA's Safe Drinking Water Act with enforceable contaminant limits.
- However, newer threats like microplastics and forever chemicals present regulatory gaps and compliance timelines.
EWG's Stricter Water Standards
- The Environmental Working Group uses stricter internal health guidelines than EPA standards to evaluate tap water.
- This causes many water systems to be flagged despite meeting federal safety limits, influencing public perception.
Choose and Maintain Filters Wisely
- Choose water filters certified by NSF or ANSI to ensure they remove contaminants effectively.
- Regularly replace filter cartridges as recommended to maintain water quality and prevent bacteria growth.
