About this trial
Groundwater in Martinsville, IN, is contaminated by volatile organic compounds (VOCs), tetrachloroethylene (PCE) and trichloroethylene (TCE). Indoor air in some residential and commercial buildings is also contaminated with PCE and TCE. This study is being conducted to better understand the impact of low-level exposures to these compounds on community members' health. Data collected in this study will be used to help the community identify a course of action.
