EPA Science Matters: March 27, 2018

If you live in a city with a Village Green station, monitoring air quality can be as easy as a walk in the park. EPA’s Village Green stations are park benches with innovative air quality measurement systems built right into them. Anyone interested in establishing their own Village Green-like station can learn how by viewing the new instructional manual and video.

EPA awarded $800,000 to the University of North Carolina at Chapel Hill to examine lead in well water and its potential impact on children’s developmental health. Working with the State of North Carolina and using healthcare, education, and water infrastructure data for their research, the UNC team will assess the association between lead in private well water and children’s blood lead levels.

Low-cost air sensor technologies continue to become more readily available. But the need to accurately characterize the air quality data remains a challenge. EPA researchers are working with Aeroqual, a New Zealand-based company specializing in the development of air quality monitoring equipment, to evaluate and advance these new technologies.

The next generation of scientists and engineers are ready to change the world. EPA awarded a total of $463,000 to 31 student teams to develop their ideas to solve real environmental problems. The awards are Phase 1 of EPA's P3 program, a two phase competition where college students design environmental solutions that benefit people, promote prosperity, and protect the planet. 

Over the course of a day, we may encounter different levels of air pollutants. Tracking these exposures is important to understanding their impacts on our health. EPA researchers developed the MicroTrac model to enhance exposure assessments by correctly identifying where people are when they are exposed to air pollution.
