PRIVATE WELLS ARE THE DRINKING WATER SOURCE FOR OVER 43 MILLION U.S. HOUSEHOLDS AND ARE VULNERABLE TO CONTAMINATION FROM ENVIRONMENTAL HAZARDS DURING SEVERE WEATHER, ESPECIALLY THOSE HOUSEHOLDS NEAR CONTAMINATED SITES. THIS PROJECT WILL ASSESS THE IMPACTS OF EXPOSURE TO CONTAMINATED GROUNDWATER ON BIRTH OUTCOMES. RESEARCHERS WILL SYNTHESIZE SOIL, HYDROLOGICAL, METEOROLOGICAL AND BUILT INFRASTRUCTURE DATA ALONGSIDE A STATEWIDE DATABASE OF PRIVATE WELL TESTING TO PREDICT CONTAMINATION EVENTS USING ECONOMETRIC AND MACHINE LEARNING TECHNIQUES.
