The Iowa Tracking Network includes data in the following areas:

Air Quality

Air pollution is associated with health problems that include increased emergency department visits and hospitals stays for breathing and heart problems, asthma, and increases in illnesses such as pneumonia and bronchitis.


Asthma is a chronic disease that affects the airways that carry oxygen in and out of the lungs. If a person has asthma, the inside of these airways is irritated and swollen. Asthma can cause shortness of breath, wheezing, coughing, and tightness in the chest.

Birth Defects

Birth defects can have many causes including genetic mutations, chromosomal abnormalities, environmental exposures, nutrition, and/or random events in the prenatal period. Many defects are thought to be a combination of these factors.


Cancer is not just one disease but many different diseases, with more than 100 different types. Cancer is one of the most common chronic diseases in the United States and is on the verge of becoming the number one cause of death in Iowa.

Carbon Monoxide Poisoning

Carbon monoxide (CO) fumes can build up in places that do not have a good flow of fresh air, such as a garage or a house with closed windows and doors. Breathing high levels of CO can cause severe illness or death in a matter of minutes.

Climate and Health

The climate is a principle aspect of the environment we live in, affecting the air we breathe, the water we drink, and the food we eat.  In recent years, concerns about the influence of human activities on climate change have increased.


Chronic Obstructive Pulmonary Disease (COPD) plays a large role in death and disability in the United States. It is the third leading cause of death and approximately 15 million Americans are diagnosed with COPD.

Heart Attacks

Several factors can be involved in the increased risk for heart attacks. These factors can include health, lifestyle, and environment. Increases in air pollution have been linked to decreases in lung function and increases in heart attacks.

Heat Related Illness

Heat Illness includes a range of health impacts caused by heat stress from milder conditions like heat rash and heat cramps, to the most common type, heat exhaustion. The most serious heat-related illness is heat stroke.

Lead Poisoning

Lead poisoning can cause learning disabilities, behavioral problems, and, at very high levels, seizures, coma, and even death. This is why routine blood lead testing is required for Iowa Children and for workers in some industries.

Private Well Water

The groundwater that supplies your water well can become contaminated through natural processes and human related activities. It is important to periodically sample and test private well water to assess the health related safety of the water source.

Public Drinking Water

The U.S. Environmental Protection Agency (EPA) sets regulations for treating and monitoring drinking water delivered by community water systems. Water quality standards and monitoring requirements are in place for more than 90 contaminants.

Reproductive Health and Birth Outcomes

Adverse reproductive and birth outcomes may include infertility, low birth weight, prematurity, and fetal and infant death. Research on reproductive and birth outcomes have improved understanding of the risks of several substances found in the environment.
