Monitoring and Assessment Programs

EPA Region 9 provides technical assistance to State and Territorial monitoring and assessment programs and grant funding to support the operation of these programs. Region 9 also conducts special monitoring studies to improve our understanding of water quality in the Region. For example, the Western Environmental Monitoring and Assessment Program currently implements several monitoring studies designed to generate state and regional scale assessments of the condition of ecological resources in the western United States.
