Scientists Scramble to Assess Depth of Ocean Damage Sparked by LA Wildfires

Toxic Ash from LA Wildfires Raises Concerns of Ocean Contamination

- 

LOS ANGELES: On a recent Sunday, Tracy Quinn drove down the Pacific Coast Highway to assess damage wrought upon the coastline by the Palisades Fire.

The water line was darkened by ash. Burnt remnants of washing machines and dryers and metal appliances were strewn about the shoreline. Sludge carpeted the water's edge. Waves during high tide lapped onto charred homes, pulling debris and potentially toxic ash into the ocean as they receded.

"It was just heartbreaking," said Quinn, president and CEO of the environmental group Heal the Bay, whose team has reported ash and debris some 25 miles (40 kilometers) south of the Palisades burn area west of Los Angeles. As crews work to remove potentially hundreds of thousands of tons of hazardous materials from the Los Angeles wildfires, researchers and officials are trying to understand how the fires on land have impacted the sea.
