Alkaline Batteries

In years past alkaline batteries (such as regular  AA, and 9-volt) contained significant levels of mercury, a hazardous heavy metal.  Today, most alkaline batteries contain far less mercury, resulting in less potential for soil and water contamination.  Virginia law permits residents to dispose of small quantities of alkaline batteries in the trash.  

You can also choose to purchase rechargeable batteries, and use AC adapters when possible.
