When most people hear asbestos, they probably think of the toxic, fibrous mineral once commonly found in construction, insulation and fireproofing materials.
When Fairfax County builders hear asbestos, they may think deeper — as in two to three feet beneath their feet.
Roughly 10.5 square miles of the county, 2.5 percent of its total size, contain “problem soils” that may include naturally occurring asbestos, specifically actinolite and tremolite minerals. It is found along the Piney Branch Complex, a vein of bedrock locally known as greenstone for its green or blue-green hue.
And the area of problem soils is getting larger.
The Fairfax County Board of Supervisors has scheduled an Oct. 15 public hearing to consider an amendment to the 2011 county soils map that will increase the potential area of naturally occurring asbestos from 10.53 to 10.67 miles. It is a slight increase, based on field work by the Northern Virginia Soil and Water Conservation District, but it is one that all developers must be aware of, as it will affect how they proceed with construction projects.

Work crews unknowingly loosened the dangerous fibers when they began replacing windows at the Carmel Park Apartments several weeks ago.
State health officials say the asbestos was in a texture compound on existing drywall, and that some of the drywall had been cut away to remove the old windows and install the new.
They say just a small amount of material was loosened in the affected apartments.
The contamination wasn’t discovered until a repairman, who knew there was asbestos in the popcorn ceiling, told the window installers there “might” be asbestos in the drywall texture.
“They tested it and found asbestos,” said Christopher Dann of the Air Pollution Control Division of the Colorado Department of Public Health and Environment.
Apartment management then sent a note to affected tenants asking them to move out temporarily while licensed crews clean up the contamination. Read More
