Iron turns Danville creek a suspicious color

Officials investigating possible dumping of oxide substance

by Geoff Gillette

Hazardous waste crews from the San Ramon Valley Fire Protection District were dispatched early last week after a call of a strange discoloration in the waters of the San Ramon Creek, south of Greenbrook Drive along the Iron Horse Trail.

District Information Officer Kim French said a jogger on the trail noticed the water had a strange red-orangish coloring and notified officials. French said that two engines, a hazardous materials truck and three chief officers converged on the scene.

The hazardous waste crew, along with officials from the Contra Costa Environmental Health Department and the California Department of Fish and Wildlife began testing the water to determine what was causing the phenomenon.

French said officials found the agent in the water to be some sort of iron or oxide. It was determined that the levels did not pose a danger to humans or animals.

Both the county environmental health department and the Department of Fish and Wildlife are continuing to investigate how the substance got into the water, saying that possibly someone dumped it into the creek.
