Emerging Contaminant Monitoring
Unregulated microorganisms and synthetic or naturally-occurring chemicals that are not commonly monitored by water utilities are termed contaminants of emerging concern (CECs). More than 100,000 chemicals are registered in the US, and new chemicals and microorganisms continue to be identified. Some of these contaminants can be detected at extremely low levels in the environment by ever-improving laboratory methods. The health significance of these trace contaminants is typically unknown. We are proactively addressing CECs through participation in national research projects and conducting independent monitoring of our source and treated waters.
