We’re having fun drinking from "Anything But a Cup" today, but protecting the water inside that quirky container? That’s the serious part.

Our drinking water begins at local streams that lead to the Potomac River and Occoquan Reservoir. Pollution that enters those sources raises treatment costs and affects water quality.
