On December 22, 2003, the San Simeon earthquake occurred and resulted in significant damage to public and private facilities. The calamity also released a geothermal hot spring in the Paso Robles City Hall parking lot, resulting in a surface flow of spring water.

In order to develop a sustainable, long-term solution, the City and AECOM performed a thorough evaluation of alternatives for treating, utilizing, or discharging this water. Odor, temperature, TDS, chlorides, and sulfide concentrations were significant challenges in identifying reuse alternatives.

The selected alternative, a system of infiltration galleries and pipelines to convey flow to the Salinas River, minimized odor concerns, power requirements, and water quality impacts by promoting subsurface mixing with groundwater. The project is currently under construction.

Keywords: Sulfur spring; earthquake; infiltration gallery; sulfides
