This EPA report is based on the 2023 Post-fire Research and Monitoring Symposium that was organized by the Oregon Governor’s Post-fire Science Team and was held February 7-9, 2023 at Oregon State University. The Symposium aimed to increase awareness among those conducting post-fi...

In 2015, U.S. EPA initiated a study to examine the potential impacts to groundwater quality from the use of GI and the results will be presented in this report. This study was conducted under the Safe and Sustainable Water Resources program (SSWR). An overarching objective of the...

The Watershed Management Optimization Support Tool (WMOST) was developed by the United States Environmental Protection Agency (US EPA) to facilitate integrated water resources management. The new Benefits Module for WMOST enables stakeholders to calculate the value of additional ...

Over the last 40 years, Narragansett Bay has experienced significant water quality improvements in response to reductions in nitrogen, heavy metal and organic contaminants, and bacterial pathogen discharge. The sources of these pollutants stem from the long history of population ...

Fish communities in river networks provide significant ecosystem services that will likely decline under future land use, human water demand, and climate variability. Modeling can be used to assess the consequences to multiple populations of one or more fish species from multiple...

The Fertilizer Emission Scenario Tool for CMAQ (FEST-C v1.4) is a Java-based interface system that facilitates the integration of agriculture, atmosphere, and hydrology simulations at large scales through the current release of the Spatial Allocator (SA v4.3.2) Raster Tools syste...

EPA announced the release of the final document,<i> Climate Change and Interacting Stressors: Implications for Coral Reef Management in American Samoa</i>. This report provides a synthesis of information on the interactive effects of climate change and other stressors on the reef...

The United States Environmental Protection Agency's (EPA) Water Modeling Workgroup (WMW) provides support for core surface water quality modeling tools used in Clean Water Act programs. The WMW identified a set of 18 separate surface water modeling applications that are currently...

Green infrastructure (GI) technologies applied to stormwater are developed to mimic natural infiltration and hydrologic processes. GI is a design strategy that enhances runoff storage volume, infiltrates runoff, and contributes to groundwater recharge. Urban development often lea...

Near-coastal (0-200 depth) ecosystems and species are under threat from increasing temperatures, ocean acidification, and sea level rise. However, species vary in their vulnerability to specific climatic changes and climate impacts will vary geographically. For management to resp...

This report was prepared by the Global Change Research Program (GCRP) in the National Center for Environmental Assessment (NCEA) of the Office of Research and Development (ORD) at the U.S. Environmental Protection Agency (EPA). This draft report is a review of decision-making pro...

Aquifer recharge (AR) is a technical method being utilized to enhance groundwater resources through man-made replenishment means, such as infiltration basins and injections wells. Aquifer storage and recovery (ASR) furthers the AR techniques by withdrawal of stored groundwater at...

The Watershed Management Optimization Support Tool (WMOST) is a decision support tool that facilitates integrated water management at the local or small watershed scale. WMOST models the environmental effects and costs of management decisions in a watershed context, accounting fo...

This final report provides an overarching summary of the pilot research project, including the methods used in and the findings of the quantitative and qualitative assessments. It is written to appeal to a wide audience of policy makers, managers, agency staff and the general pub...

EPA announced the availability of the final report, <em>Effects of Climate Change on Aquatic Invasive Species and Implications for Management and Research </em>. This report reviews available literature on climate-change effects on aquatic invasive species (AIS) and examines sta...

Anaerobic digestion is a natural biological process in which microorganisms break down organic materials in the absence of oxygen. When anaerobic microbes metabolize organic waste – i.e., the carbon-based remains of plants, animals and their waste products, e.g. animal manure, se...

EPA announced the availability of the draft report, <em>Updates to the Demographic and Spatial Allocation Models to Produce Integrated Climate and Land Use Scenarios (ICLUS)</em> for a 30-day public comment period. The ICLUS version 2 (v2) modeling tool furthered land change mod...
