Rapid Benefit Indicators (RBI) Approach

An easy-to-use process for assessing restoration sites using non-monetary benefit indicators.

Development of saliva-based exposure assays for detecting exposure to waterborne pathogens

Identifying which pathogens we are exposed to can be challenging because many types of pathogens can be found in water and many pathogens have similar symptoms. EPA scientists have developed a simple way to measure human exposure to waterborne pathogens.
