Environmental Health Investigations branch


The Environmental Health Investigations Branch (EHIB) studies and explains how the health of our environment affects our health. We provide information that can help reduce human exposure to harmful environmental risks. Our mission is to protect the health of all Californians by identifying environmental hazards, partnering with communities to build their capacity, and promoting healthy environments.
