‘Smoke School’ Teaches DNREC Air Quality Engineers to Identify Smoke

Not all smoke is created equal. Smoke can vary greatly in color, smell, wetness, velocity and thickness. And with special training, individuals can use some of those traits to assess an emission source’s compliance status. For years, engineers in the Delaware Department of Natural Resources and Environmental Control’s Division of Air Quality have gone to “smoke school” twice a year to learn how to read smoke based on the opacity, or how much light is visible through it.
