Dispute over cause of dead fish

HENRICO, VA (WWBT) - Hundreds of dead fish were removed from two Henrico ponds today, but the question remains -- just what killed them?

On Friday, state officials said the cause appeared to be traced to a broken water main that dumped chlorinated water into the Winchester Green ponds.

The director of Henrico's Department of Public Utilities disputes the claim.

Henrico DPU says they're still investigating.
