The harmful effects of indoor air contaminants, such as perchloroethylene (PERC), are clear. Knowing how to assess our own risk is less clear. We will assemble and distribute air quality test kits to homes in Northeast Denver in order to collect data on two pollutants: PERC and radon. Our goals are simple, help a local community understand if they are at risk, raise awareness of air quality issues, and test a low-cost method for PERC detection that could allow anyone to screen their home.
