When dealing with water damage in your home or business, there are three different types or classifications of water that we use: Clean, Gray, and Black water.

Clean Water: This is water that does not contain contaminants. It includes broken water lines, malfunctioning appliances, toilets holding tanks, snow melt and rainwater. Overtime however, clean water can progress and become gray water within 48 hours, if left untreated.

Gray Water: Gray water does contain slight chemical or biological contaminants, and may pose a health risk. Gray water can discharge from dishwashers, washing machines, sinks, showers, aquariums and waterbeds, or come from a clean water source that leaked through a ceiling. It can also be clean water that was left untreated (and became gray water). Gray water can also progress to the next stage (Black Water) if left untreated within 48 hours.

Black Water: This water is a positive health risk as it is highly contaminated. Black water is presumed to contain multiple potentially harmful contaminants including fungi, bacteria, chemicals, viruses, and more. Black Water is typically caused by sewage damage, flooding, or any type of natural disaster. Black water should always be treated by a trained and certified professional.

For any type of water damage, it is always best to treat it quickly so as to avoid further contamination and risk mold growth. Call SERVPRO of Tustin if you need services in your home! Available 24/7 (714)480-1340
