CT DPH Evaluation of Exposures to Chemical Contamination in the Environment

The Site Assessments and Chemical Risk Unit evaluates exposure and health risks at locations in Connecticut where real or perceived chemical contamination is a concern. A Cooperative Agreement grant from the Agency for Toxic Substances and Disease Registry (ATSDR) funds this work.

 

This page provides information about locations in Connecticut where documents for the public have been prepared by the CT Department of Public Health or by ATSDR. The documents may include public health assessments, health consultations and fact sheets. The documents on this page evaluate chemical contamination in the environment at a site or location and assess whether the contamination could harm people’s health if they are exposed to the contamination. 

 

Documents are organized by town and can be accessed using the A-Z Town list below.
