3 Types of Contaminated Water
Water damage can be classified by the three types of contaminated water. SERVPRO technicians will inspect your home or business to determine the appropriate plan of action for the type of water encountered.
The three types of contaminated water:
Category 1: "Clean Water"
Category 1 water is from a clean source like a broken water supply line or leaking faucet. If not treated quickly, this water can turn into category 2 or 3, depending on length of time, temperature, and contact with surrounding contaminants.
- Water from a clean source like a broken water line
- If left untreated, can degrade into category 2 or 3
Category 2: "Gray Water"
Category 2 water is contaminated and could cause discomfort or illness. Examples include washing machine overflow; toilet overflow with some urine, but no feces; or dishwasher overflow.
- May contain bacteria and viruses
- Can quickly degrade into category 3 if left untreated
Category 3: "Black Water"
Category 3 water is grossly contaminated and could cause severe illness or death if ingested and any contact should be avoided. Examples include flooding from rivers or streams, water from beyond the toilet trap, water from the toilet bowl with feces, or standing water that has begun to support microbial growth.
- May contain untreated sewage, harsh chemicals, and microbes
- Water from flooding rivers or sewer backup
