Designing a citywide groundwater treatment program to safeguard public health
PFAS contamination threatened Anaheim’s drinking water, putting millions at risk. The city and CDM Smith acted quickly to design and implement the largest interconnected multiple-well PFAS treatment program in the U.S. This multi-phase effort ensures regulatory compliance, restores groundwater reliability and delivers safe drinking water efficiently and cost-effectively.
Optimized operational flexibility
A robust facility design allows for future adjustments while maintaining system reliability.
Accelerated construction schedule
A design-build approach enabled rapid deployment despite supply chain challenges and an ambitious timeline.
Engaging stakeholders for a safe water future
Collaboration with city agencies and the county's water district safeguarded groundwater and delivered long-term access.
Anaheim has begun reaping the benefits of the nation’s largest interconnected multi-facility PFAS treatment program. The program treats 73.2 mgd of drinking water through facilities at nine locations, providing safe drinking water to customers. It sets a benchmark for scale, speed, and innovation in PFAS mitigation. “We need to give credit to these cities and agencies for going through this tremendous effort to bring safe, clean water to their communities,” says Roshan Aflaki, CDM Smith vice president and PFAS expert.
