After nearly a decade of funding cuts under the Bush Administration, this bill appropriates a much needed 15% increase in funding over the previous fiscal year for the Department of Interior, the Environmental Protection Agency, the Forest Service and other related agencies.  The bill provides $10.3 billion in funding for the EPA alone, $2.7 billion more than in 2009. 

Some water related funding highlights:

A total of $3.6 billion to help communities improve their drinking water and wastewater systems:
 - $2.1 billion for the Clean Water State Revolving Fund
- $1.38 billion for the Drinking Water State Revolving Fund
- $157 million for direct grants to communities for water infrastructure
- A substantial portion of the SRF will be available as grants and subsidized loans to communities that cannot afford to pay back conventional loans.
- As was required in the American Recovery and Reinvestment Act of 2009, 20% of all projects funded through the Clean Water and Drink Water State Revolving Funds must incorporate green infrastructure or water efficiency techniques. 

A total of $641 million to clean up and protect the nation's great water bodies including:
- $475 million for the Great Lakes Restoration Initiative
- $50 million for the Puget Sound
- $50 million for the Chesapeake Bay
- $7 million for the San Francisco Bay

In addition, the 2010 Interior Appropriations Bill includes $1.5 billion for hazardous waste/toxic site clean-up and $385 million for programs that address climate change.
