Campbell County students are doing their part to improve water quality in the James River.
Fifth graders at Tomahawk Elementary spent the afternoon Friday marking storm drains at their school.
They posted signs warning people not to dump trash or waste, because the pipes carry water to the James River. They also spent time picking up trash around the drains.
Friday's event is part of a campaign called "Chose Blue," organized by the James River Association. It's a regional effort to show how polluted storm water can damage local streams and rivers.
"We only want water going into the river; avoiding trash, grass, fertilizers, or oils to protect our watershed and enhance water quality," said Adrienne Kotula, policy coordinator for the James River Association.
Experts say storm water runoff is one of the fastest growing sources of pollution in the James River.
