More than 400 tons of debris, 13,950 needles and 5,279 pounds of hazardous waste were discovered in Santa Ana River Trail in California between January 22 and March 3.

The waste was from a more than two-mile stretch of bike trail from around the I-5 in Orange to Ball Road in Anaheim, the OCR reported.

Hazardous waste includes human waste, propane and pesticides.

The Santa Ana River Trail was once populated by homeless people, but the encampments were dismantled in late February.
