In Alameda County Friday, crews removed fertilizers and other harmful chemicals that were left behind by marijuana growers.

3,000 marijuana plants were seized from the site from the property owned by East Bay Regional Parks District last July, but the growers got away.

Officials say the chemicals and pesticides run off into creeks and they are harmful to local wildlife. They affect everything from insects to larger animals such as deer.
