The Challenge
The Geysers known geothermal resource area (KGRA) is the world’s largest complex of geothermal power plants, located about 8 miles northeast of Geyserville, California. The Geothermal wells that were drilled to provide generators with steam are known to emit hydrogen sulfide that can impact the surrounding communities. The Geysers Air Monitoring Program (GAMP) was established in 1976 to provide the community with meteorology and hydrogen sulfide concentrations data related to the Geysers KGRA.
Our Solution
In 2022, the GAMP committee chose Spheros Environmental to conduct the operations of all monitoring equipment and the data reporting. Since then, the Northern California measurements team has successfully transitioned into the project and maintained high data quality and completeness. The Spheros team has modernized the data acquisition and telemetry hardware to ensure efficient serviceability into the future. Field technicians conduct weekly calibrations of the instrumentation and address any technical problems that arise.

Results +What makes this unique
Spheros has ensured high data quality by conducting routine and expert maintenance and performing frequent internal audits. Third-party audits by the California Air Resources Board verified the excellent results. Our rigorous quality assurance program subjects the data to multiple stages of review before it is finalized and uploaded into the U.S. Environmental Protection Agency’s central database. Every quarter, Sphero’s subject matter expert/project manager meets with the GAMP committee to communicate key aspects of the collected data and the overall status of the project.
