Water is one of Pennsylvania's most precious and basic resources. Pennsylvanians use 14.3 billion gallons of water every day. Almost all of it -- 13.7 billion gallons -- is returned to the environment. That means that each of us has a special responsibility to use water in ways that do not harm aquatic life and other water users downstream.
But we also must be concerned about water in other ways.What we do to the land, affects the health of our streams, lakes and other bodies of water.The connection between the land and water is made through a watershed.
