A spokesman for the water company said they were investigating whether the roadkill ended up on their land and had tainted the water supply. SARATOGA – State workers have dumped thousands of dead animals killed on roadways into a ravine over the past decade, and many of the carcasses rolled into a creek leading to a popular picnic area, officials said. Dead deer, raccoons and other animals were tossed over a steep cliff off a highway that runs near land owned by San Jose Water Co. near Saratoga. The California Department of Transportation acknowledged that at least two of its workers have used the ravine as a dumping ground in violation of agency regulations. “From what I understand, one person has been doing this for as long as 10 years,” said Lauren Wonder, a Caltrans spokeswoman.
