One priority identified by GOMA is the need to improve detection methods for water quality indicators, pathogens and microbial source tracking. The United States Environmental Protection Agency (USEPA) is tasked with revising water quality criteria by 2012; however, the locations traditionally studied ...
1. Review current designated uses and criteria for a set of waterbodies. 2. Describe SABS effects on the waterbodies’ designated uses. 3. Select specific SABS criteria and biological response indicators. 4. Define potential ranges in values of the SABS and biological response indicators. 5. Id...
improved air quality, improved freshwater water quality and reductions in persistent toxic chemicals in the aquatic food web. The indicators representing populations of wild species, including marine species at risk and Chinook salmon abundance, need more attention. Two habitat indicators sensitive to ...

'Viral' Criteria]]>Wastewater groups are urging EPA to better justify the need for developing water quality criteria based on indicators of viral pathogens, saying current scientific knowledge appears insufficient to support such criteria and that an agency literature review failed to demonstrate the ...
The index of biotic integrity (IBI), first developed by James Karr in 1981 to assess the health of small warmwater streams, uses fish sampling data to give a quantitative measure of pollution. Twelve indicators of stream health, appropriate to the geographical area, including the total number ...
Approximately 30 studies are now underway across the United States as part of the Nationwide Urban Runoff program (NURP) to evaluate the water quality significance of stormwater drainage from urban areas. This program is under the guidance and control of the U. S. EPA 208 program offices in ...
EPA’s 2003 Draft Report on the Environment (RoE) provides a snapshot of the state of the environment across air, water, and land systems.8 Indicators were defined in relation to clearly stated questions, such as “what are the trends and conditions of surface waters?” The Draft RoE ...
Among other topics, the EPA solicits comment on 1) key metrics and indicators that the agency should use to measure progress in reducing plastic and 2) other waste in waterways and oceans and whether the agency should expand the scope of the strategy to include sea-based sources. Comments ...
