Up to 70% of pollution in streams,
rivers and lakes comes from storm water runoff.
urban runoff and energy
crop and forest lands,
and eroding stream banks
Salt from irrigation practices and acid drainage from abandoned mines
faulty septic systems
Impervious surfaces (ones that do not allow water to percolate or drain through soil such as buildings, parking lots, etc) contribute runoff water and increase the amount of pollutants in runoff.
A garden designed specifically to improve water quality.
Near the house to catch only roof run off or out on the lawn to catch water from the lawn and roof
55-60% of the drain area
Dylan’s house is 50 feet by 40 feet so the roof area is 2000 sq ft. (50 x 40 = 2000)
He has two downspouts and will plant a rain garden in the back yard which will collect water from approximately half of the roof area or 1000 sq ft.
His soil is mostly clay so the size of the rain garden should be approximately 550 sq ft. (1000 x .55 = 550)
Financial and other support for this project is provided by the Pennsylvania Association of Conservation Districts, Inc. through a grant with the U.S. Environmental Protection Agency’s Section 319 Program.
