Automobiles, power plants, industry, etc., all contribute to today's air pollution problem. The principal pollutants from these activities, including
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.
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.
Monitoring Ground-Level Ozone
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.
Current 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 fifteen minutes 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. The Bureau of Air Quality uses "discrete" or manual method monitoring for three Criteria pollutants - Lead, PM2.5, and PM10. A discrete method is generally a "manual" method of sampling, most commonly using an air filter to trap air pollutants from ambient air for a defined, or "discrete" period of time.
2018 Ambient Air Monitoring Network Plan
EPA, state, and local agencies work together to report current and forecast conditions for ozone and particle pollution. AIRNow forecasts next-day air quality.
Pennsylvania Environmental Public Health Tracking Program
Provides information from state and national networks of health and environmental data that improves the public health of Pennsylvania communities. This includes:
- Air quality
- Drinking water quality
- Hospitalization for asthma, heart attacks, heat stress and carbon monoxide poisoning
- Carbon monoxide mortality
- Housing age
- Reproductive health outcomes
- Cancer incidence
Air 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.
