Environmental health includes the conditions we live in that we cannot individually control, but that can affect our health. These conditions include the air we breathe, the water we drink, and the food we eat. St. Louis County Public health works to provide guidance and education on reducing environmental hazards in our homes and communities. Our staff work with residents to help identify potential areas of concern, such as lead, mold, radon, tickborne diseases, animal bites and rabies risk, and public health nuisances.
