Lead in soil can be a hazard when children play in bare soil or when people bring soil into the house on their shoes. The following two federal standards have been set for lead hazards in residential soil: 400 parts per million (ppm) and higher in play areas of bare soil; 1,200 ppm (average) and higher in bare soil in the remainder of the yard. The only way to find out if soil lead hazards exist is to test.
Water damage can quickly lead to biological pollutants in your home. Follow these guidelines for correcting water damage: Throw out mattresses, wicker furniture, straw baskets and the like that have been water damaged or contain mold. Discard any water-damaged furnishings such as carpets, drapes, stuffed toys, upholstered furniture and ceiling tiles, unless they can be recovered by steam cleaning or hot water washing and thorough drying. Remove and replace wet insulation to prevent conditions where biological pollutants can grow.
