The Agency for Toxic Substances and Disease Registry (ATSDR) and Texas Department of State Health Services (DSHS) are conducting an extensive review of environmental health concerns raised by the community members in Midlothian, Texas to determine if chemical releases from local industries could or have affected the health of persons and animals in the area.

ATSDR is a health agency of the U.S. Department of Health and Human Services. ATSDR serves the public by using the best science, taking responsive public health actions, and providing trusted health information to prevent harmful exposures and diseases related to toxic substances. ATSDR and DSHS will review environmental and health data and prepare a series of health consultations to summarize their health findings.



On November 16, 2012, ATSDR released a health consultation [PDF, 4.83 MB] for public comment that describes the public health implications of exposures to hydrogen sulfide and the National Ambient Air Quality Standard (NAAQS) pollutants. NAAQS pollutants are PM2.5, ozone, sulfur dioxide, nitrogen oxides, carbon monoxide, and lead.

ATSDR is conducting additional health consultations to answer environmental health questions related to air, soil, water, sediment, health effects, and animal issues in Midlothian. ATSDR will release the additional health consultations with the results of its evaluation when the reports are completed.
