Air Quality Monitoring
The District operates several local air monitoring stations within its tri-county jurisdiction of Humboldt, Del Norte and Trinity counties. Different pollutants may be monitored depending upon the site equipment of the station.
There are currently four monitoring sites in the District where particulate matter samples are collected: Crescent City, Eureka (2), and Weaverville. By analyzing the samples collected, District staff is able to determine the concentration particulate matter sized less than 2.5 microns in size (PM2.5). Sample data is then reported to the federal database which is maintained by the Environmental Protection Agency.
Air monitoring stations are typically small buildings which contain sampling and monitoring equipment. They are usually accompanied by a meteorological station to measure wind speed, direction, temperature, and humidity. Meteorological information is collected to assist in determining the origin of pollution events and is used when preparing healthrisk assessments.
