New water components have been added to the Federal Green Challenge. Now it includes the goal of decreasing stormwater runoff from existing sites by 5% or more annually and a section focusing on reducing the use of federal funds to purchase bottled water. Launched in October 2011, the Challenge is a national effort led by EPA's Sustainable Materials Management Program that challenges federal agencies to lead by example to reduce the federal government's environmental impact. Participating agencies will benefit from the new water components. Effective stormwater management through the use of green infrastructure practices may result in: improved energy, efficiency, and improved site aesthetics. Since green infrastructure techniques may be less expensive than conventional stormwater management approaches, there may also be cost savings.
