An LAist story on contaminated debris from a massive fire at a World War II-era hangar in Tustin cited Gregory Pierce, co-executive director of the UCLA Luskin Center for Innovation. Lead, arsenic and asbestos have been detected in some ash and debris tested in the air and on the ground. While some groundwater has been contaminated, toxins are unlikely to make their way into drinking water systems, the story noted. Pierce, who directs the Human Right to Water Solutions Lab, said he has confidence in local water suppliers and official monitoring bodies to manage any potentially toxic effects from the fire on the water system. He added that the volume of toxic sediment that could reach waterways is likely small and diffuse and therefore unlikely to have a big impact on surface water quality.
