Environmentally Friendly Mold Remediation Techniques That Significantly Reduce Childhood Asthma• “Moderate” Problem should be applied to:o areas larger than 10 sqft of contiguous contaminationbut less than 100 sqft.• “Major” Problem should be applied to:ovisibly mold-contaminated surfaces that are larger in areathan 100 sqft.For all problems, the possibility of extensive hiddencontamination should be explored during the investigation phasein order to adequately plan remediation efforts.2. Density of Contamination In addition to the surface area of moldgrowth, the density of mold growth should be considered inrelation to the contaminated material and the potential for hiddengrowth. Heavily contaminated materials may contain many moremold particulates than surfaces with very light and superficialgrowth over a larger area. Always keep in mind that when hiddengrowth is possible or porous materials are contaminated, a higherproblem category should be considered.• “Minimal” Problem should be applied to situations in whichvisible growth is mainly limited to scattered small colonieswhere evidence suggests that these are only present on easilyaccessible non-porous surfaces.• “Moderate” Problem should be applied to:oolight and spotty visible growth on porous or semi-porousmaterials, orwhen other evidence (for example, a significant moistureproblem or mold odors) suggests that additional hiddencontamination may be present;• “Major” Problem should be applied to:o a heavy distribution of many large colonies on any typeof material, or58
