Relevant excerpt / notes
The page distinguishes PFAS detected in groundwater at MCAS Yuma above DoW interim action levels from the five private wells sampled in 2023, none of which had detections at or above the interim levels. It says the 2026 area is expanded and 2023 wells are to be resampled because laboratory methods improved. The page lists additional appointment times upon request after the scheduled September 30 to October 7 window.
