Automobiles, power plants, industry, etc., all contribute to today's
air pollution problem. The principal pollutants from these activities,
including carbon monoxide, lead, nitrogen dioxide, ozone,
particulate matter, and sulfur dioxide, can be particularly detrimental
to the health of "sensitive" populations such as asthmatics,
children, and the elderly. Pennsylvania and the federal government
have set concentration standards for these principal
pollutants to protect the public's health and to prevent environmental
damage. To ensure that areas of Pennsylvania attain
these standards, the DEP monitors these principal pollutants.
Monitoring Data and Results
Air Quality Index
The AQI reports on levels of five major air
pollutants in your area: ozone, particulate matter, sulfur dioxide,
carbon monoxide and nitrogen dioxide. Reports are updated hourly
at half-past the hour.
and Historical Pollution Levels and Weather
Check out the current and past pollution levels in your area including weather parameters. The most current data is updated hourly at half-past the hour. The Daily Site Detail report shows all parameters at a single site for any given day. The Monthly Parameter Detail report shows all data for a month at a time for a single site and parameter. The Parameter Comparison report displays all 1-hour data for a parameter at all sites by day. The Ranked Averages report allows you to show the maximum values for a parameter (including 8-hour and 24-hour averages for certain pollutants) at a site over a user defined time period.
Allegheny County Pollution Levels
The Allegheny County Health Department is now posting hourly data to the web, updated approximately 30 minutes past the hour.
Final Report - Special Carlisle Area Fine Particulate Air Monitoring Study
As a result of concerns raised by local residents due to the increased emissions from truck traffic, Carlisle area residents, the Clean Air Board of Central Pennsylvania (CAB), and the Department of Environmental Protection (PA DEP) conducted an ambient air quality study focusing on fine particulate matter (PM2.5) in the Carlisle area. The Department collected PM2.5 data from May 10, 2007 to September 30, 2008. Results of the study and the entire report can be viewed by clicking on the link above.

Ambient Annual Air Quality Report
This report contains summaries of the air quality data collected
by the DEP's Bureau of Air Quality.
EPA, state, and local agencies work together
to report current and forecast conditions for ozone and particle
pollution. AIRNow forecasts next-day air quality.

Air Quality: Status and Trends
National air quality levels measured at thousands
of monitoring stations across the country have shown improvements
over the past 20 years.

Air Quality Partnership
The Air Quality Partnership is a public/private
coalition dedicated to improving air quality. This web site contains
information on two of the most important pollutants found in Pennsylvania's
air: ground-level ozone and fine particulate matter. Forecasts
are made daily on the predicted levels of each pollutant.

Quality Learning and Demonstration Center
As part of the Arboretum at Penn State, this
center offers a balanced and research-based approach to educating
the general public, school children, and University classes about
air quality and its effects on native plants and trees.
