Flood water falls into three categories. Determining which category your problem falls into is important in determining the best course of action to take. However, it is critical to seek assistance immediately, because category 1 waters can worsen into category 2 or 3 very quickly.
Category 1—clear water
This type of flooding usually entails clean water that originates from a source--such as a broken pipe or water heater--that does not present an immediate danger to humans or animals.
Category 2- grey water
If the flood water appears to be grey, filmy, or murky it may contain a significant level of contamination, which could cause discomfort or sickness to humans exposed to it. Clear water may become murky or fall into category 2 within 24-72 hours.
Category 3- black water
Black water, which may occur in situations involving mass flooding or sewage, is extremely dangers. It contains significant microbial and pathogenic agents and is unsanitary. You should make every effort to prevent your family members or pets from being exposed to this category of flood waters.
