Haley & Aldrich helps Palm Springs safely and efficiently comply with airport-related PFAS order

3 groundwater monitoring wells

installed in under three weeks

130 soil samples

taken in under three weeks


  • The California State Water Board ordered the city of Palm Springs to conduct a comprehensive audit of aqueous film-forming foam (AFFF) storage, use, and management at its airport. AFFF used at airports contains per- and polyfluoroalkyl substances (PFAS), which some studies have linked to health problems in humans. Because AFFF can potentially impact the environment, the state required the city to determine if any contamination had occurred.  
  • Drawing on our deep experience providing geochemical and environmental services to airports, we designed a practical and timely plan to locate PFAS sources and investigate potential contamination without impacting airport operations. 
  • We sampled soil across the site using two drilling techniques at the same time — one for shallower soil sampling and another for deeper soil sampling — to complete the work on a tight timeline.  
  • We also proactively engaged the California Regional Water Quality Control Board by inviting representatives to a site walk at the start of the field program, discussing sampling locations and objectives with them, and received approval for a phased investigation approach based on initial laboratory results.
