The Challenge
Complex Waste Disposal Issues Across California
California is home to thousands of legacy waste disposal sites—some poorly documented, others entirely abandoned. Many of these sites pose significant risks to public health, safety, and the environment. Identifying, assessing, and mitigating these risks requires not only technical expertise but a deep understanding of evolving regulatory landscapes and environmental complexities.
Over the past two decades, CalRecycle has turned to Ninyo & Moore, a SOCOTEC company, to support its Closed, Illegal, and Abandoned Sites (CIA) Program. These projects are not confined to a single region or landfill; they span diverse terrains and community settings statewide, each presenting unique challenges—from incomplete historical data and unknown contaminants to budgetary and regulatory constraints.

The Solution
A Collaborative, On-Call Approach to Environmental Investigation

For ten consecutive contract periods over 20 years, Ninyo & Moore has delivered responsive, expert support for the CIA Sites Program. As part of this enduring relationship, our team has conducted over 100 waste disposal site investigations across California.
Key elements of our approach include:
- Thorough Site Characterization: Our teams performed comprehensive historical assessments to identify potential waste activities, combined with geophysical surveys to map subsurface anomalies.
- Field Investigations: We deployed teams to ensure accurate data collection under strict health and safety protocols.
- Landfill Gas Monitoring Systems: Installation and monitoring of systems that detect methane and other gases helped determine site safety and inform mitigation strategies.
- Regulatory Navigation: Our specialists worked closely with CalRecycle and oversight agencies to ensure full compliance with environmental regulations, streamlining approvals and action plans.
- Data Integration and Reporting: By integrating analytical testing results and historical data, we provided CalRecycle with clear, actionable insights into each site's status and risk.
What sets this project apart is not just its technical scope but the level of collaboration between Ninyo & Moore, a SOCOTEC Company, and CalRecycle. Project managers at CalRecycle have come to see our team as an extension of their own staff—a testament to our trusted partnership and consistent delivery.
