Air Quality Information
There are currently no air quality advisories for Rock County.
The DNR uses the Air Quality Index (AQI) that was developed to make it easier to understand the health significance of air pollution levels. Each AQI category has a specific color assigned to make it easier to quickly determine the air quality in communities. For up-to-date information, visit Department of Natural Resources.
What is an Air Quality Watch?
An Air Quality Watch is issued when conditions are favorable for air pollutants to reach unhealthy levels based on the Air Quality Index (AQI).
What is an Advisory?
An Air Quality Advisory is issued when air pollutants have reached unhealthy levels based on the AQI.

Keeping Food Safe During an Emergency
Did you know a flood, fire, national disaster, or the loss of power from high winds, snow, or ice could jeopardize the safety of your food? Knowing how to determine if food is safe and how to keep food safe will help minimize the potential loss of food and reduce the risk of foodborne illness.
Q: Some of the food in my freezer started to thaw or had thawed when the power came back on. Is the food safe? How long will the food in the refrigerator be safe with the power off?
- Never taste food to determine its safety! You will have to evaluate each item separately. If the appliance thermometer stored in the freezer reads 40 degrees or below, the food is safe and may be refrozen. If a thermometer has not been kept in the freezer, check each package of food to determine safety. Remember you can't rely on appearance or color. If the food contains ice crystals or is 40 degrees or below, it is safe to refreeze. Refrigerated foods should be safe as long as power is out no more than 4 hours. Keep the door closed as much as possible. Discard any perishable food (such as meat, poultry, fish, eggs and leftovers) that have been above 40 degrees for 2 hours.
