The Connecticut Environmental Public Health Tracking Program (EPHT) focuses on collecting data in order to protect our communities from health issues related to environmental factors. Our program manages a Data Explorer which is part of a national network created in cooperation with the Centers for Disease Control and Prevention (CDC) to provide health, exposure and environmental hazard data and information that communities can use to improve their health.
Data include topics such as: air quality, asthma, carbon monoxide poisoning, heart attack, Lyme disease, and water quality.
