The Massachusetts Environmental Public Health Tracking, or EPHT, program has transitioned its web content to Mass.gov.
The new EPHT pages provide improved navigation, increased accessibility, and a more consistent experience for people looking for environmental health information, data, and visualization tools. These updates are intended to make it easier for residents, communities, public health partners, and other users to find and use EPHT resources that support public health planning, decisions, and action.
Users are encouraged to explore the new EPHT pages and update any saved bookmarks.

We work to protect the public from a variety of environmental exposures. These exposures can occur when we come into contact with pollutants in the air, water, or soil – whether they result from human activities or the natural environment, like radon in soil.
