Residential Wood Burning Survey

The Environmental Services Division of the health department monitors year-round the fine-particulate air pollution in the Air Pollution Control District (see map at right).

It also enforces local outdoor air-quality regulations that were adopted to protect the health of area residents by controlling emissions of fine particulate pollution, also known as PM2.5

Fine-particulate air pollution includes soot, combustion byproducts, and liquid pollutants in the air.

Exposure to fine particulates can harm human health, especially among individuals with existing lung diseases. Studies have linked fine-particulate pollution to an increase in hospital admissions and emergency room visits.
