According to James Petersen, the senior writer on the website, there are three categories of water that can enter a home either during or after a flood. The first category is water that does not pose a major threat to humans. The second category is water which contains biological, physical or chemical contaminants and may cause sickness if it is consumed or used on the body. The third category is Black water. It is the most dangerous for both humans and household pets and it should be avoided.
Mr. Petersen said, “Back water is extremely unsanitary because it contains harmful fungi and bacteria.” Black water may originate from sewer lines, rivers and streams. The last two categories mentioned above have the potential to change into black water if the water is not removed from a home in a timely fashion.
There are four classes of water damage all of which are explained on the Water Extraction Services (http://waterdamagerestorationatlanta.org/
The first class of water damage covers those objects in a room with hard surfaces. The second class covers items that have a fast rate of evaporation and the third class is the fastest rate of evaporation. Class four requires special drying situations and includes hardwood floors, concrete basement floors or garage floors, plaster and crawl spaces.
