Released by the National Research Council this 2011 report examines a wide range of reuse applications, including potable water, non-potable urban and industrial uses, irrigation, groundwater recharge, and ecological enhancement. With recent advances in technology and design, treating municipal wastewater and reusing it for drinking water, irrigation, industry, and other applications could significantly increase the nation's total available water resources, particularly in coastal areas facing water shortages, says a new report from the National Research Council. It adds that the reuse of treated wastewater, also known as reclaimed water, to augment drinking water supplies has significant potential for helping meet future needs. Moreover, new analyses suggest that the possible health risks of exposure to chemical contaminants and disease-causing microbes from wastewater reuse do not exceed, and in some cases may be significantly lower than, the risks of existing water supplies.

Water Utility COVID-19 Financial Impact Tool can help drinking water, wastewater, and stormwater ("water") utilities assess the financial impact of the COVID-19 pandemic on the utility's cashflow. This tool leads water utilities through questions that can determine how their revenues, expenses, and cashflow have been affected by the COVID-19 pandemic. The spreadsheet automatically calculates the changes for a utility's revenues and expenses by looking at current 2020 monthly financials versus the average monthly financials of the utility's 2019 audited financial statement. Water utilities can use the tool each month to keep a running total of their cashflow.

This September 2014 handbook is intended to advance the use of a "watershed approach" in the selection, design, and siting of wetland and stream restoration and protection projects. Using a watershed approach can help ensure that these projects also contribute to goals of improved water quality, increased flood mitigation, improved quality and quantity of habitat, and increases in other services and benefits that result from ecologically successful and sustainable restoration and protection projects. This report was prepared by the Environmental Law Institute (ELI) and The Nature Conservancy (TNC) with funding from the U.S. Environmental Protection Agency (EPA).

An integrated information system for the nation's surface waters. The EPA Office of Water manages numerous programs in support of the Agency's water quality efforts. Many of these programs collect and store water quality related data in databases. Under WATERS, the Water Program databases are connected to a larger framework which is a digital network of surface water features, known as the National Hydrography Dataset (NHD) By linking to the NHD, one Water Program database can reach another, and information can be shared across programs.

This Web site offers a variety of self-paced training modules that represent a basic and broad introduction to the watershed management field. The modules are organized by the following six themes:

• Introductory/Overview Modules
• Watershed Ecology Modules
• Watershed Change Modules
• Analysis and Planning Modules
• Management Practices Modules
• Community/Social/Water Law Modules

Modules vary in the time they to complete, from ½ hour to 2 hours. Fifteen of them are the core modules for the Watershed Academy Certificate Program.

WMOST is a decision support tool that facilitates integrated water management at the local or small watershed scale. Integrated water management involves coordination across multiple programs for land, water, and related resources (stormwater, wastewater, drinking water, land conservation) to find sustainable and cost-effective solutions. WMOSTv3 has an associated theoretical documentation report as well as a detailed user guide. While version 2 only included management options related to water quantity, version 3 of WMOST also includes water quality management. Users can identify least-cost solutions to meet water quality criteria for lakes or streams/rivers, pollutant loading targets, and/or minimization of combined sewer overflows. Version 3 also includes riparian buffer zone restoration or conservation, a few agricultural BMPs, and additional stormwater best management practices, both structural, such as rain gardens and nonstructural, such as street sweeping. The Hydroprocessor, a program which formats output from watershed models such as SWAT and HSPF for input to WMOST, is also included.

These decision trees were developed by EPA and the Department of Energy s National Renewable Energy Lab (NREL), to screen potentially contaminated and underutilized sites for solar and wind potential. While the decision tree focuses on potentially contaminated sites, this tool also provides information on rooftop and other applications in order to support complimentary evaluations. These decision trees can be used to screen individual sites for their solar or wind potential or for a community-scale evaluation of multiple sites.

Interior Secretary Gale Norton has signed a record of decision (ROD) that establishes guidelines for wind energy development and expedites approval of proposed projects in Western states. The programmatic environmental impact statement (EIS) for wind energy development establishes mitigation measures, best management practices, and other guidelines for wind energy development on Bureau of Land Management lands. The document, completed as a requirement of NEPA, will serve as the basis for environmental reviews of individual projects. By "tiering" off the programmatic EIS, individual projects would require less lengthy environmental assessments, and as a result, proposed wind projects could be approved in less than 1 yr, as opposed to 2 yr or longer.
