Environmental Factors

Many things in the environment can affect our health. Environmental public health is the branch of public health that focuses on the relationship between the environment and human health. Our department's environmental public health professionals work to help reduce health risks from exposure to potentially harmful substances in air, water, soil and food. Health officials also provide information to communities about exposure to hazardous substances and sites while discussing ways to reduce exposure until the risk is eliminated.

Overall, environmental public health plays an important role in protecting the well-being of communities by making sure the places we live, work and play are safe.

Lead

Lead poisoning is one of the most common and preventable environmental health problems in Missouri. Childhood lead exposure can cause learning and behavioral problems, lower IQ, kidney damage, and interfere with growth and hearing. The only way to know if your child has lead poisoning is to have their blood tested. 

Indoor Air

Clean indoor air is necessary for good health. Indoor air pollutants can contribute to asthma and allergic reactions, chemical poisoning and some types of cancer. The quality of indoor air is a significant health concern throughout the state because Missourians spend an average of 90% of their time inside. Research shows that air pollution levels are higher indoors than outside.

Radon

Radon is a colorless, odorless and tasteless gas that poses a health risk to humans when it is found inside homes and other buildings. Exposure to radon is the second leading cause of lung cancer. You can test your home for radon and take steps to reduce the level of radon in indoor air.

Septic Systems

Onsite wastewater treatment systems are used by about 25% of all homes in Missouri. Sewage systems that are not operating correctly can create a health risk. In most areas of Missouri, you must get a permit to construct an onsite sewage system from our department (DHSS) or a local public health agency.

Wastewater Surveillance

Wastewater from communities is monitored for genetic indicators of viruses and other diseases. This surveillance approach helps to track the prevalence of many diseases in communities across the state.

Water Wells

Thousands of Missourians get their water from a private water supply, usually a well. Our department works to make sure that drinking water is safe. We provide technical assistance to homeowners and local public health agencies regarding water testing and treatment. The program also regulates private water supplies of hotels, motels and restaurants to make sure the water meets safe drinking water standards.
