Stream Monitoring Network

EPA researchers are working with EPA regions, states (including Georgia), Tribes, river basin commissions and other entities to establish Regional Monitoring Networks for freshwater wadeable streams. The objectives are to collect long-term biological, thermal, hydrologic, physical habitat and water chemistry data to document baseline conditions across sites and detect long-term changes. This data can be used for many purposes, including informing water quality and biological criteria development and setting protection planning priorities, refining lists of biological, thermal and hydrologic indicators, and detecting trends in commonly used water quality and biological indicators.

Performance Evaluation of Popular Air Sensors

There is wide interest from air monitoring agencies, researchers, and community groups in deploying smaller, more portable air sensor technologies for community-scale air monitoring projects. First, air sensors need to be thoroughly evaluated in order to understand their limitations and data quality. EPA partnered with six air monitoring agencies, including the Georgia Environmental Protection Division, to operate five air sensor types alongside standard regulatory monitors so that data could be compared.

Reducing Harmful Air Pollutants

For more than 25 years, EPA and states have been using EPA's Community Multiscale Air Quality (CMAQ) Modeling System, a powerful computational tool for air quality management. CMAQ simultaneously models multiple air pollutants, including ozone, particulate matter, and a variety of air toxics to help air quality managers determine the best air quality management scenarios for their states and communities. The Georgia Environmental Protection Division uses CMAQ to develop and assess implementation actions needed to attain National Ambient Air Quality Standards mandated by the Clean Air Act.
