Particulate Alerts


 What are these and how can I help?


The Evansville Environmental Protection Agency and the Vanderburgh County Health Department Ozone Office review data from ambient air quality monitors and weather forecasts provided by the National Weather Service to predict particulate levels. 


Whenever it seems likely that fine particulate (PM2.5) levels in Southwest Indiana, averaged over a twenty-four hour period may reach U.S.EPA's National Ambient Air Quality Standard (NAAQS) of 35 micrograms per cubic meter, the Evansville Environmental Protection Agency, in cooperation with the Vanderburgh County Health Department Ozone Office will declare a PARTICULATE ALERT.


Active adults, children, people with heart or respiratory problems and people who have diabetes, should protect their health by limiting the length and intensity of exertion until air quality improves.  It's important to know that particulate levels can be much higher indoors than outdoors.  Using an indoor air filter may be helpful.


Remember NO OUTDOOR BURNING is allowed during Particulate Alerts.  Use of charcoal and gas grills is permitted, but if you can postpone outdoor grilling, please do, because even gas and charcoal add to air pollution.


To help reduce pollution levels:

            CONSERVE ENERGY - limit use of electricity, natural gas, gasoline and diesel fuel.

            Limit your driving.

            Postpone fueling your vehicle if possible until air quality improves. 

            Park and go inside instead of using drive-through windows.

            Avoid unnecessary vehicle idling..

            Postpone mowing your grass or using gas-powered lawn equipment.

            Postpone painting and limit solvent use.
