The Three Different Categories of Water
When a water event occurs in your property, damage to the structure and contents can occur. The type of water that affects a building includes:
Category 1 water originates from a sanitary water source and does not pose substantial risk from dermal, ingestion, or inhalation exposure. In most cases drying procedures are recommended.
Category 2 water contains significant contamination and has the potential to cause discomfort or sickness if contacted by people. For this category, environmental interpretation is critical as drying for some materials is acceptable while removal of others must occur
Category 3 water is grossly contaminated and can contain pathogenic, toxigenic or other harmful agents. In most cases removal is necessary and environmental remediation is necessary.
When a water event occurs a water extraction contractor is generally hired to remove the water. However, the ability of the contractor to identify the water category, deal with the issues of health and safety properly as well as remove or dry out the affected building materials and contents can vary greatly.
Assessment for water damage independently of the water removal contractor ensures that the project is dealt with relative to the category of water, health and safety concerns are identified and controlled and their work product is validated.
